 BOSTOCK v. CLAYTON COUNTY, GEORGIA

CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
 THE ELEVENTH CIRCUIT

 No. 17–1618. Argued October 8, 2019—Decided June 15, 2020*
In each of these cases, an employer allegedly fired a long-time employee
 simply for being homosexual or transgender. Clayton County, Geor-
 gia, fired Gerald Bostock for conduct “unbecoming” a county employee
 shortly after he began participating in a gay recreational softball
 league. Altitude Express fired Donald Zarda days after he mentioned
 being gay. And R. G. & G. R. Harris Funeral Homes fired Aimee Ste-
 phens, who presented as a male when she was hired, after she in-
 formed her employer that she planned to “live and work full-time as a
 woman.” Each employee sued, alleging sex discrimination under Title
 VII of the Civil Rights Act of 1964. The Eleventh Circuit held that
 Title VII does not prohibit employers from firing employees for being
 gay and so Mr. Bostock’s suit could be dismissed as a matter of law.
 The Second and Sixth Circuits, however, allowed the claims of Mr.
 Zarda and Ms. Stephens, respectively, to proceed.
Held: An employer who fires an individual merely for being gay or
 transgender violates Title VII. Pp. 4–33.
 (a) Title VII makes it “unlawful . . . for an employer to fail or refuse
 to hire or to discharge any individual, or otherwise to discriminate
 against any individual . . . because of such individual’s race, color, re-
 ligion, sex, or national origin.” 42 U. S. C. §2000e–2(a)(1). The
 straightforward application of Title VII’s terms interpreted in accord

 with their ordinary public meaning at the time of their enactment re-
 solves these cases. Pp. 4–12.
 (1) The parties concede that the term “sex” in 1964 referred to the
 biological distinctions between male and female. And “the ordinary
 meaning of ‘because of’ is ‘by reason of’ or ‘on account of,’ ” University
 of Tex. Southwestern Medical Center v. Nassar, 570 U. S. 338, 350 .
 That term incorporates the but-for causation standard, id., at 346, 360 ,
 which, for Title VII, means that a defendant cannot avoid liability just
 by citing some other factor that contributed to its challenged employ-
 ment action. The term “discriminate” meant “[t]o make a difference in
 treatment or favor (of one as compared with others).” Webster’s New
 International Dictionary 745. In so-called “disparate treatment”
 cases, this Court has held that the difference in treatment based on
 sex must be intentional. See, e.g., Watson v. Fort Worth Bank & Trust,
 487 U. S. 977, 986 . And the statute’s repeated use of the term “indi-
 vidual” means that the focus is on “[a] particular being as distin-
 guished from a class.” Webster’s New International Dictionary, at
 1267. Pp. 4–9.
 (2) These terms generate the following rule: An employer violates
 Title VII when it intentionally fires an individual employee based in
 part on sex. It makes no difference if other factors besides the plain-
 tiff’s sex contributed to the decision or that the employer treated
 women as a group the same when compared to men as a group. A
 statutory violation occurs if an employer intentionally relies in part on
 an individual employee’s sex when deciding to discharge the employee.
 Because discrimination on the basis of homosexuality or transgender
 status requires an employer to intentionally treat individual employ-
 ees differently because of their sex, an employer who intentionally pe-
 nalizes an employee for being homosexual or transgender also violates
 Title VII. There is no escaping the role intent plays: Just as sex is
 necessarily a but-for cause when an employer discriminates against
 homosexual or transgender employees, an employer who discriminates
 on these grounds inescapably intends to rely on sex in its decisionmak-
 ing. Pp. 9–12.
 (b) Three leading precedents confirm what the statute’s plain terms
 suggest. In Phillips v. Martin Marietta Corp., 400 U. S. 542 , a com-
 pany was held to have violated Title VII by refusing to hire women
 with young children, despite the fact that the discrimination also de-
 pended on being a parent of young children and the fact that the com-
 pany favored hiring women over men. In Los Angeles Dept. of Water
 and Power v. Manhart, 435 U. S. 702 , an employer’s policy of requiring
 women to make larger pension fund contributions than men because
 women tend to live longer was held to violate Title VII, notwithstand-
 ing the policy’s evenhandedness between men and women as groups.

 Syllabus

And in Oncale v. Sundowner Offshore Services, Inc., 523 U. S. 75 , a
male plaintiff alleged a triable Title VII claim for sexual harassment
by co-workers who were members of the same sex.
 The lessons these cases hold are instructive here. First, it is irrele-
vant what an employer might call its discriminatory practice, how oth-
ers might label it, or what else might motivate it. In Manhart, the
employer might have called its rule a “life expectancy” adjustment, and
in Phillips, the employer could have accurately spoken of its policy as
one based on “motherhood.” But such labels and additional intentions
or motivations did not make a difference there, and they cannot make
a difference here. When an employer fires an employee for being ho-
mosexual or transgender, it necessarily intentionally discriminates
against that individual in part because of sex. Second, the plaintiff’s
sex need not be the sole or primary cause of the employer’s adverse
action. In Phillips, Manhart, and Oncale, the employer easily could
have pointed to some other, nonprotected trait and insisted it was the
more important factor in the adverse employment outcome. Here, too,
it is of no significance if another factor, such as the plaintiff’s attrac-
tion to the same sex or presentation as a different sex from the one
assigned at birth, might also be at work, or even play a more important
role in the employer’s decision. Finally, an employer cannot escape
liability by demonstrating that it treats males and females comparably
as groups. Manhart is instructive here. An employer who intention-
ally fires an individual homosexual or transgender employee in part
because of that individual’s sex violates the law even if the employer
is willing to subject all male and female homosexual or transgender
employees to the same rule. Pp. 12–15.
 (c) The employers do not dispute that they fired their employees for
being homosexual or transgender. Rather, they contend that even in-
tentional discrimination against employees based on their homosexual
or transgender status is not a basis for Title VII liability. But their
statutory text arguments have already been rejected by this Court’s
precedents. And none of their other contentions about what they think
the law was meant to do, or should do, allow for ignoring the law as it
is. Pp. 15–33.
 (1) The employers assert that it should make a difference that
plaintiffs would likely respond in conversation that they were fired for
being gay or transgender and not because of sex. But conversational
conventions do not control Title VII’s legal analysis, which asks simply
whether sex is a but-for cause. Nor is it a defense to insist that inten-
tional discrimination based on homosexuality or transgender status is
not intentional discrimination based on sex. An employer who discrim-
inates against homosexual or transgender employees necessarily and
intentionally applies sex-based rules. Nor does it make a difference
4 BOSTOCK v. CLAYTON COUNTY

 Syllabus

 that an employer could refuse to hire a gay or transgender individual
 without learning that person’s sex. By intentionally setting out a rule
 that makes hiring turn on sex, the employer violates the law, whatever
 he might know or not know about individual applicants. The employ-
 ers also stress that homosexuality and transgender status are distinct
 concepts from sex, and that if Congress wanted to address these mat-
 ters in Title VII, it would have referenced them specifically. But when
 Congress chooses not to include any exceptions to a broad rule, this
 Court applies the broad rule. Finally, the employers suggest that be-
 cause the policies at issue have the same adverse consequences for
 men and women, a stricter causation test should apply. That argu-
 ment unavoidably comes down to a suggestion that sex must be the
 sole or primary cause of an adverse employment action under Title VII,
 a suggestion at odds with the statute. Pp. 16–23.
 (2) The employers contend that few in 1964 would have expected
 Title VII to apply to discrimination against homosexual and
 transgender persons. But legislative history has no bearing here,
 where no ambiguity exists about how Title VII’s terms apply to the
 facts. See Milner v. Department of Navy, 562 U. S. 562 , 574. While it
 is possible that a statutory term that means one thing today or in one
 context might have meant something else at the time of its adoption
 or might mean something different in another context, the employers
 do not seek to use historical sources to illustrate that the meaning of
 any of Title VII’s language has changed since 1964 or that the statute’s
 terms ordinarily carried some missed message. Instead, they seem to
 say when a new application is both unexpected and important, even if
 it is clearly commanded by existing law, the Court should merely point
 out the question, refer the subject back to Congress, and decline to en-
 force the law’s plain terms in the meantime. This Court has long re-
 jected that sort of reasoning. And the employers’ new framing may
 only add new problems and leave the Court with more than a little law
 to overturn. Finally, the employers turn to naked policy appeals, sug-
 gesting that the Court proceed without the law’s guidance to do what
 it thinks best. That is an invitation that no court should ever take up.

 JUSTICE GORSUCH delivered the opinion of the Court.
2 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

 Sometimes small gestures can have unexpected conse-
quences. Major initiatives practically guarantee them. In
our time, few pieces of federal legislation rank in signifi-
cance with the Civil Rights Act of 1964. There, in Title VII,
Congress outlawed discrimination in the workplace on the
basis of race, color, religion, sex, or national origin. Today,
we must decide whether an employer can fire someone
simply for being homosexual or transgender. The answer
is clear. An employer who fires an individual for being ho-
mosexual or transgender fires that person for traits or ac-
tions it would not have questioned in members of a different
sex. Sex plays a necessary and undisguisable role in the
decision, exactly what Title VII forbids.
 Those who adopted the Civil Rights Act might not have
anticipated their work would lead to this particular result.
Likely, they weren’t thinking about many of the Act’s con-
sequences that have become apparent over the years, in-
cluding its prohibition against discrimination on the basis
of motherhood or its ban on the sexual harassment of male
employees. But the limits of the drafters’ imagination sup-
ply no reason to ignore the law’s demands. When the ex-
press terms of a statute give us one answer and extratex-
tual considerations suggest another, it’s no contest. Only
the written word is the law, and all persons are entitled to
its benefit.
 I
 Few facts are needed to appreciate the legal question we
face. Each of the three cases before us started the same
way: An employer fired a long-time employee shortly after
the employee revealed that he or she is homosexual or
transgender—and allegedly for no reason other than the
employee’s homosexuality or transgender status.
 Gerald Bostock worked for Clayton County, Georgia, as a
child welfare advocate. Under his leadership, the county
won national awards for its work. After a decade with the
 Cite as: 590 U. S. ____ (2020) 3

 Opinion of the Court

county, Mr. Bostock began participating in a gay recrea-
tional softball league. Not long after that, influential mem-
bers of the community allegedly made disparaging com-
ments about Mr. Bostock’s sexual orientation and
participation in the league. Soon, he was fired for conduct
“unbecoming” a county employee.
 Donald Zarda worked as a skydiving instructor at Alti-
tude Express in New York. After several seasons with the
company, Mr. Zarda mentioned that he was gay and, days
later, was fired.
 Aimee Stephens worked at R. G. & G. R. Harris Funeral
Homes in Garden City, Michigan. When she got the job,
Ms. Stephens presented as a male. But two years into her
service with the company, she began treatment for despair
and loneliness. Ultimately, clinicians diagnosed her with
gender dysphoria and recommended that she begin living
as a woman. In her sixth year with the company, Ms. Ste-
phens wrote a letter to her employer explaining that she
planned to “ live and work full-time as a woman” after she
returned from an upcoming vacation. The funeral home
fired her before she left, telling her “this is not going to work
out.”
 While these cases began the same way, they ended differ-
ently. Each employee brought suit under Title VII alleging
unlawful discrimination on the basis of sex. 78 Stat. 255 ,
42 U. S. C. §2000e–2(a)(1). In Mr. Bostock’s case, the Elev-
enth Circuit held that the law does not prohibit employers
from firing employees for being gay and so his suit could be
dismissed as a matter of law. 723 Fed. Appx. 964 (2018).
Meanwhile, in Mr. Zarda’s case, the Second Circuit con-
cluded that sexual orientation discrimination does violate
Title VII and allowed his case to proceed. 883 F. 3d 100 
(2018). Ms. Stephens’s case has a more complex procedural
history, but in the end the Sixth Circuit reached a decision
along the same lines as the Second Circuit’s, holding that
Title VII bars employers from firing employees because of
4 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

their transgender status. 884 F. 3d 560 (2018). During the
course of the proceedings in these long-running disputes,
both Mr. Zarda and Ms. Stephens have passed away. But
their estates continue to press their causes for the benefit
of their heirs. And we granted certiorari in these matters
to resolve at last the disagreement among the courts of ap-
peals over the scope of Title VII’s protections for homosex-
ual and transgender persons. 587 U. S. ___ (2019).
 II
 This Court normally interprets a statute in accord with
the ordinary public meaning of its terms at the time of its
enactment. After all, only the words on the page constitute
the law adopted by Congress and approved by the Presi-
dent. If judges could add to, remodel, update, or detract
from old statutory terms inspired only by extratextual
sources and our own imaginations, we would risk amending
statutes outside the legislative process reserved for the peo-
ple’s representatives. And we would deny the people the
right to continue relying on the original meaning of the law
they have counted on to settle their rights and obligations.
See New Prime Inc. v. Oliveira, 586 U. S. ___ , ___–___
(2019) (slip op., at 6–7).
 With this in mind, our task is clear. We must determine
the ordinary public meaning of Title VII’s command that it
is “unlawful . . . for an employer to fail or refuse to hire or
to discharge any individual, or otherwise to discriminate
against any individual with respect to his compensation,
terms, conditions, or privileges of employment, because of
such individual’s race, color, religion, sex, or national
origin.” §2000e–2(a)(1). To do so, we orient ourselves to the
time of the statute’s adoption, here 1964, and begin by ex-
amining the key statutory terms in turn before assessing
their impact on the cases at hand and then confirming our
work against this Court’s precedents.

 Opinion of the Court

 A
 The only statutorily protected characteristic at issue in
today’s cases is “sex”—and that is also the primary term in
Title VII whose meaning the parties dispute. Appealing to
roughly contemporaneous dictionaries, the employers say
that, as used here, the term “sex” in 1964 referred to “status
as either male or female [as] determined by reproductive
biology.” The employees counter by submitting that, even
in 1964, the term bore a broader scope, capturing more than
anatomy and reaching at least some norms concerning gen-
der identity and sexual orientation. But because nothing in
our approach to these cases turns on the outcome of the par-
ties’ debate, and because the employees concede the point
for argument’s sake, we proceed on the assumption that
“sex” signified what the employers suggest, referring only
to biological distinctions between male and female.
 Still, that’s just a starting point. The question isn’t just
what “sex” meant, but what Title VII says about it. Most
notably, the statute prohibits employers from taking cer-
tain actions “because of ” sex. And, as this Court has previ-
ously explained, “the ordinary meaning of ‘because of ’ is ‘by
reason of ’ or ‘on account of.’ ” University of Tex. Southwest-
ern Medical Center v. Nassar, 570 U. S. 338, 350 (2013) (cit-
ing Gross v. FBL Financial Services, Inc., 557 U. S. 167, 176 
(2009); quotation altered). In the language of law, this
means that Title VII’s “because of ” test incorporates the
“ ‘simple’ ” and “traditional” standard of but-for causation.
Nassar, 570 U. S., at 346, 360 . That form of causation is
established whenever a particular outcome would not have
happened “but for” the purported cause. See Gross, 557
U. S., at 176 . In other words, a but-for test directs us to
change one thing at a time and see if the outcome changes.
If it does, we have found a but-for cause.
 This can be a sweeping standard. Often, events have
multiple but-for causes. So, for example, if a car accident
6 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

occurred both because the defendant ran a red light and be-
cause the plaintiff failed to signal his turn at the intersec-
tion, we might call each a but-for cause of the collision. Cf.
Burrage v. United States, 571 U. S. 204 , 211–212 (2014).
When it comes to Title VII, the adoption of the traditional
but-for causation standard means a defendant cannot avoid
liability just by citing some other factor that contributed to
its challenged employment decision. So long as the plain-
tiff ’s sex was one but-for cause of that decision, that is
enough to trigger the law. See ibid.; Nassar, 570 U. S., at
350 .
 No doubt, Congress could have taken a more parsimoni-
ous approach. As it has in other statutes, it could have
added “solely” to indicate that actions taken “because of ”
the confluence of multiple factors do not violate the law. Cf.
 11 U. S. C. §525 ; 16 U. S. C. §511 . Or it could have written
“primarily because of ” to indicate that the prohibited factor
had to be the main cause of the defendant’s challenged em-
ployment decision. Cf. 22 U. S. C. §2688 . But none of this
is the law we have. If anything, Congress has moved in the
opposite direction, supplementing Title VII in 1991 to allow
a plaintiff to prevail merely by showing that a protected
trait like sex was a “motivating factor” in a defendant’s
challenged employment practice. Civil Rights Act of 1991,
§107, 105 Stat. 1075 , codified at 42 U. S. C. §2000e–2(m).
Under this more forgiving standard, liability can sometimes
follow even if sex wasn’t a but-for cause of the employer’s
challenged decision. Still, because nothing in our analysis
depends on the motivating factor test, we focus on the more
traditional but-for causation standard that continues to af-
ford a viable, if no longer exclusive, path to relief under Ti-
tle VII. §2000e–2(a)(1).
 As sweeping as even the but-for causation standard can
be, Title VII does not concern itself with everything that
happens “because of ” sex. The statute imposes liability on
 Cite as: 590 U. S. ____ (2020) 7

 Opinion of the Court

employers only when they “fail or refuse to hire,” “dis-
charge,” “or otherwise . . . discriminate against” someone
because of a statutorily protected characteristic like sex.
Ibid. The employers acknowledge that they discharged the
plaintiffs in today’s cases, but assert that the statute’s list
of verbs is qualified by the last item on it: “otherwise . . .
discriminate against.” By virtue of the word otherwise, the
employers suggest, Title VII concerns itself not with every
discharge, only with those discharges that involve discrim-
ination.
 Accepting this point, too, for argument’s sake, the ques-
tion becomes: What did “discriminate” mean in 1964? As
it turns out, it meant then roughly what it means today:
“To make a difference in treatment or favor (of one as com-
pared with others).” Webster’s New International Diction-
ary 745 (2d ed. 1954). To “discriminate against” a person,
then, would seem to mean treating that individual worse
than others who are similarly situated. See Burlington N.
& S. F. R. Co. v. White, 548 U. S. 53, 59 (2006). In so-called
“disparate treatment” cases like today’s, this Court has also
held that the difference in treatment based on sex must be
intentional. See, e.g., Watson v. Fort Worth Bank & Trust,
 487 U. S. 977, 986 (1988). So, taken together, an employer
who intentionally treats a person worse because of sex—
such as by firing the person for actions or attributes it
would tolerate in an individual of another sex—discrimi-
nates against that person in violation of Title VII.
 At first glance, another interpretation might seem possi-
ble. Discrimination sometimes involves “the act, practice,
or an instance of discriminating categorically rather than
individually.” Webster’s New Collegiate Dictionary 326
(1975); see also post, at 27–28, n. 22 (ALITO, J., dissenting).
On that understanding, the statute would require us to con-
sider the employer’s treatment of groups rather than indi-
viduals, to see how a policy affects one sex as a whole versus
the other as a whole. That idea holds some intuitive appeal
8 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

too. Maybe the law concerns itself simply with ensuring
that employers don’t treat women generally less favorably
than they do men. So how can we tell which sense, individ-
ual or group, “discriminate” carries in Title VII?
 The statute answers that question directly. It tells us
three times—including immediately after the words “dis-
criminate against”—that our focus should be on individu-
als, not groups: Employers may not “fail or refuse to hire
or . . . discharge any individual, or otherwise . . . discrimi-
nate against any individual with respect to his compensa-
tion, terms, conditions, or privileges of employment, be-
cause of such individual’s . . . sex.” §2000e–2(a)(1)
(emphasis added). And the meaning of “individual” was as
uncontroversial in 1964 as it is today: “A particular being
as distinguished from a class, species, or collection.” Web-
ster’s New International Dictionary, at 1267. Here, again,
Congress could have written the law differently. It might
have said that “it shall be an unlawful employment practice
to prefer one sex to the other in hiring, firing, or the terms
or conditions of employment.” It might have said that there
should be no “sex discrimination,” perhaps implying a focus
on differential treatment between the two sexes as groups.
More narrowly still, it could have forbidden only “sexist pol-
icies” against women as a class. But, once again, that is not
the law we have.
 The consequences of the law’s focus on individuals rather
than groups are anything but academic. Suppose an em-
ployer fires a woman for refusing his sexual advances. It’s
no defense for the employer to note that, while he treated
that individual woman worse than he would have treated a
man, he gives preferential treatment to female employees
overall. The employer is liable for treating this woman
worse in part because of her sex. Nor is it a defense for an
employer to say it discriminates against both men and
women because of sex. This statute works to protect indi-
viduals of both sexes from discrimination, and does so
 Cite as: 590 U. S. ____ (2020) 9

 Opinion of the Court

equally. So an employer who fires a woman, Hannah, be-
cause she is insufficiently feminine and also fires a man,
Bob, for being insufficiently masculine may treat men and
women as groups more or less equally. But in both cases
the employer fires an individual in part because of sex. In-
stead of avoiding Title VII exposure, this employer doubles
it.
 B
 From the ordinary public meaning of the statute’s lan-
guage at the time of the law’s adoption, a straightforward
rule emerges: An employer violates Title VII when it inten-
tionally fires an individual employee based in part on sex.
It doesn’t matter if other factors besides the plaintiff ’s sex
contributed to the decision. And it doesn’t matter if the em-
ployer treated women as a group the same when compared
to men as a group. If the employer intentionally relies in
part on an individual employee’s sex when deciding to dis-
charge the employee—put differently, if changing the em-
ployee’s sex would have yielded a different choice by the em-
ployer—a statutory violation has occurred. Title VII’s
message is “simple but momentous”: An individual em-
ployee’s sex is “not relevant to the selection, evaluation, or
compensation of employees.” Price Waterhouse v. Hopkins,
 490 U. S. 228, 239 (1989) (plurality opinion).
 The statute’s message for our cases is equally simple and
momentous: An individual’s homosexuality or transgender
status is not relevant to employment decisions. That’s be-
cause it is impossible to discriminate against a person for
being homosexual or transgender without discriminating
against that individual based on sex. Consider, for exam-
ple, an employer with two employees, both of whom are at-
tracted to men. The two individuals are, to the employer’s
mind, materially identical in all respects, except that one is
a man and the other a woman. If the employer fires the
10 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

male employee for no reason other than the fact he is at-
tracted to men, the employer discriminates against him for
traits or actions it tolerates in his female colleague. Put
differently, the employer intentionally singles out an em-
ployee to fire based in part on the employee’s sex, and the
affected employee’s sex is a but-for cause of his discharge.
Or take an employer who fires a transgender person who
was identified as a male at birth but who now identifies as
a female. If the employer retains an otherwise identical
employee who was identified as female at birth, the em-
ployer intentionally penalizes a person identified as male at
birth for traits or actions that it tolerates in an employee
identified as female at birth. Again, the individual em-
ployee’s sex plays an unmistakable and impermissible role
in the discharge decision.
 That distinguishes these cases from countless others
where Title VII has nothing to say. Take an employer who
fires a female employee for tardiness or incompetence or
simply supporting the wrong sports team. Assuming the
employer would not have tolerated the same trait in a man,
Title VII stands silent. But unlike any of these other traits
or actions, homosexuality and transgender status are inex-
tricably bound up with sex. Not because homosexuality or
transgender status are related to sex in some vague sense
or because discrimination on these bases has some dispar-
ate impact on one sex or another, but because to discrimi-
nate on these grounds requires an employer to intentionally
treat individual employees differently because of their sex.
 Nor does it matter that, when an employer treats one em-
ployee worse because of that individual’s sex, other factors
may contribute to the decision. Consider an employer
with a policy of firing any woman he discovers to be a
Yankees fan. Carrying out that rule because an em-
ployee is a woman and a fan of the Yankees is a firing
“because of sex” if the employer would have tolerated the
same allegiance in a male employee. Likewise here.

 Opinion of the Court

When an employer fires an employee because she is homo-
sexual or transgender, two causal factors may be in play—
both the individual’s sex and something else (the sex to
which the individual is attracted or with which the individ-
ual identifies). But Title VII doesn’t care. If an employer
would not have discharged an employee but for that in-
dividual’s sex, the statute’s causation standard is met,
and liability may attach.
 Reframing the additional causes in today’s cases as addi-
tional intentions can do no more to insulate the employers
from liability. Intentionally burning down a neighbor’s
house is arson, even if the perpetrator’s ultimate intention
(or motivation) is only to improve the view. No less, inten-
tional discrimination based on sex violates Title VII, even if
it is intended only as a means to achieving the employer’s
ultimate goal of discriminating against homosexual or
transgender employees. There is simply no escaping the
role intent plays here: Just as sex is necessarily a but-for
cause when an employer discriminates against homosex-
ual or transgender employees, an employer who discrim-
inates on these grounds inescapably intends to rely on
sex in its decisionmaking. Imagine an employer who has
a policy of firing any employee known to be homosexual.
The employer hosts an office holiday party and invites em-
ployees to bring their spouses. A model employee arrives
and introduces a manager to Susan, the employee’s wife.
Will that employee be fired? If the policy works as the em-
ployer intends, the answer depends entirely on whether the
model employee is a man or a woman. To be sure, that em-
ployer’s ultimate goal might be to discriminate on the basis
of sexual orientation. But to achieve that purpose the em-
ployer must, along the way, intentionally treat an employee
worse based in part on that individual’s sex.
 An employer musters no better a defense by responding
that it is equally happy to fire male and female employees
who are homosexual or transgender. Title VII liability is
12 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

not limited to employers who, through the sum of all of their
employment actions, treat the class of men differently than
the class of women. Instead, the law makes each instance
of discriminating against an individual employee because
of that individual’s sex an independent violation of Title
VII. So just as an employer who fires both Hannah and Bob
for failing to fulfill traditional sex stereotypes doubles ra-
ther than eliminates Title VII liability, an employer who
fires both Hannah and Bob for being gay or transgender
does the same.
 At bottom, these cases involve no more than the straight-
forward application of legal terms with plain and settled
meanings. For an employer to discriminate against em-
ployees for being homosexual or transgender, the employer
must intentionally discriminate against individual men
and women in part because of sex. That has always been
prohibited by Title VII’s plain terms—and that “should be
the end of the analysis.” 883 F. 3d, at 135 (Cabranes, J.,
concurring in judgment).
 C
 If more support for our conclusion were required, there’s
no need to look far. All that the statute’s plain terms sug-
gest, this Court’s cases have already confirmed. Consider
three of our leading precedents.
 In Phillips v. Martin Marietta Corp., 400 U. S. 542 (1971)
(per curiam), a company allegedly refused to hire women
with young children, but did hire men with children the
same age. Because its discrimination depended not only on
the employee’s sex as a female but also on the presence of
another criterion—namely, being a parent of young chil-
dren—the company contended it hadn’t engaged in discrim-
ination “because of ” sex. The company maintained, too,
that it hadn’t violated the law because, as a whole, it tended
to favor hiring women over men. Unsurprisingly by now,
 Cite as: 590 U. S. ____ (2020) 13

 Opinion of the Court

these submissions did not sway the Court. That an em-
ployer discriminates intentionally against an individual
only in part because of sex supplies no defense to Title VII.
Nor does the fact an employer may happen to favor women
as a class.
 In Los Angeles Dept. of Water and Power v. Manhart, 435
U. S. 702 (1978), an employer required women to make
larger pension fund contributions than men. The employer
sought to justify its disparate treatment on the ground that
women tend to live longer than men, and thus are likely to
receive more from the pension fund over time. By every-
one’s admission, the employer was not guilty of animosity
against women or a “purely habitual assumptio[n] about a
woman’s inability to perform certain kinds of work”; in-
stead, it relied on what appeared to be a statistically accu-
rate statement about life expectancy. Id., at 707–708. Even
so, the Court recognized, a rule that appears evenhanded at
the group level can prove discriminatory at the level of in-
dividuals. True, women as a class may live longer than men
as a class. But “[t]he statute’s focus on the individual is
unambiguous,” and any individual woman might make the
larger pension contributions and still die as early as a man.
 Id., at 708 . Likewise, the Court dismissed as irrelevant the
employer’s insistence that its actions were motivated by a
wish to achieve classwide equality between the sexes: An
employer’s intentional discrimination on the basis of sex is
no more permissible when it is prompted by some further
intention (or motivation), even one as prosaic as seeking to
account for actuarial tables. Ibid. The employer violated
Title VII because, when its policy worked exactly as
planned, it could not “pass the simple test” asking whether
an individual female employee would have been treated the
same regardless of her sex. Id., at 711 .
 In Oncale v. Sundowner Offshore Services, Inc., 523 U. S.
75 (1998), a male plaintiff alleged that he was singled out
by his male co-workers for sexual harassment. The Court
14 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

held it was immaterial that members of the same sex as the
victim committed the alleged discrimination. Nor did the
Court concern itself with whether men as a group were sub-
ject to discrimination or whether something in addition to
sex contributed to the discrimination, like the plaintiff ’s
conduct or personal attributes. “[A]ssuredly,” the case
didn’t involve “the principal evil Congress was concerned
with when it enacted Title VII.” Id., at 79 . But, the Court
unanimously explained, it is “the provisions of our laws ra-
ther than the principal concerns of our legislators by which
we are governed.” Ibid. Because the plaintiff alleged that
the harassment would not have taken place but for his
sex—that is, the plaintiff would not have suffered similar
treatment if he were female—a triable Title VII claim ex-
isted.
 The lessons these cases hold for ours are by now familiar.
 First, it’s irrelevant what an employer might call its dis-
criminatory practice, how others might label it, or what else
might motivate it. In Manhart, the employer called its rule
requiring women to pay more into the pension fund a “life
expectancy” adjustment necessary to achieve sex equality.
In Phillips, the employer could have accurately spoken of
its policy as one based on “motherhood.” In much the same
way, today’s employers might describe their actions as mo-
tivated by their employees’ homosexuality or transgender
status. But just as labels and additional intentions or mo-
tivations didn’t make a difference in Manhart or Phillips,
they cannot make a difference here. When an employer
fires an employee for being homosexual or transgender, it
necessarily and intentionally discriminates against that in-
dividual in part because of sex. And that is all Title VII has
ever demanded to establish liability.
 Second, the plaintiff ’s sex need not be the sole or primary
cause of the employer’s adverse action. In Phillips, Man-
hart, and Oncale, the defendant easily could have pointed
to some other, nonprotected trait and insisted it was the
 Cite as: 590 U. S. ____ (2020) 15

 Opinion of the Court

more important factor in the adverse employment outcome.
So, too, it has no significance here if another factor—such
as the sex the plaintiff is attracted to or presents as—might
also be at work, or even play a more important role in the
employer’s decision.
 Finally, an employer cannot escape liability by demon-
strating that it treats males and females comparably as
groups. As Manhart teaches, an employer is liable for in-
tentionally requiring an individual female employee to pay
more into a pension plan than a male counterpart even if
the scheme promotes equality at the group level. Likewise,
an employer who intentionally fires an individual homosex-
ual or transgender employee in part because of that indi-
vidual’s sex violates the law even if the employer is willing
to subject all male and female homosexual or transgender
employees to the same rule.
 III
 What do the employers have to say in reply? For present
purposes, they do not dispute that they fired the plaintiffs
for being homosexual or transgender. Sorting out the true
reasons for an adverse employment decision is often a hard
business, but none of that is at issue here. Rather, the em-
ployers submit that even intentional discrimination against
employees based on their homosexuality or transgender
status supplies no basis for liability under Title VII.
 The employers’ argument proceeds in two stages. Seek-
ing footing in the statutory text, they begin by advancing a
number of reasons why discrimination on the basis of ho-
mosexuality or transgender status doesn’t involve discrim-
ination because of sex. But each of these arguments turns
out only to repackage errors we’ve already seen and this
Court’s precedents have already rejected. In the end, the
employers are left to retreat beyond the statute’s text,
where they fault us for ignoring the legislature’s purposes
16 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

in enacting Title VII or certain expectations about its oper-
ation. They warn, too, about consequences that might fol-
low a ruling for the employees. But none of these conten-
tions about what the employers think the law was meant to
do, or should do, allow us to ignore the law as it is.
 A
 Maybe most intuitively, the employers assert that dis-
crimination on the basis of homosexuality and transgender
status aren’t referred to as sex discrimination in ordinary
conversation. If asked by a friend (rather than a judge) why
they were fired, even today’s plaintiffs would likely respond
that it was because they were gay or transgender, not be-
cause of sex. According to the employers, that conversa-
tional answer, not the statute’s strict terms, should guide
our thinking and suffice to defeat any suggestion that the
employees now before us were fired because of sex. Cf. post,
at 3 (ALITO, J., dissenting); post, at 8–13 (KAVANAUGH, J.,
dissenting).
 But this submission rests on a mistaken understanding
of what kind of cause the law is looking for in a Title VII
case. In conversation, a speaker is likely to focus on what
seems most relevant or informative to the listener. So an
employee who has just been fired is likely to identify the
primary or most direct cause rather than list literally every
but-for cause. To do otherwise would be tiring at best. But
these conversational conventions do not control Title VII’s
legal analysis, which asks simply whether sex was a but-for
cause. In Phillips, for example, a woman who was not hired
under the employer’s policy might have told her friends that
her application was rejected because she was a mother, or
because she had young children. Given that many women
could be hired under the policy, it’s unlikely she would say
she was not hired because she was a woman. But the Court
did not hesitate to recognize that the employer in Phillips
discriminated against the plaintiff because of her sex. Sex
 Cite as: 590 U. S. ____ (2020) 17

 Opinion of the Court

wasn’t the only factor, or maybe even the main factor, but
it was one but-for cause—and that was enough. You can
call the statute’s but-for causation test what you will—ex-
pansive, legalistic, the dissents even dismiss it as wooden
or literal. But it is the law.
 Trying another angle, the defendants before us suggest
that an employer who discriminates based on homosexual-
ity or transgender status doesn’t intentionally discriminate
based on sex, as a disparate treatment claim requires. See
post, at 9–12 (ALITO, J., dissenting); post, at 12–13
(KAVANAUGH, J., dissenting). But, as we’ve seen, an em-
ployer who discriminates against homosexual or
transgender employees necessarily and intentionally ap-
plies sex-based rules. An employer that announces it will
not employ anyone who is homosexual, for example, intends
to penalize male employees for being attracted to men and
female employees for being attracted to women.
 What, then, do the employers mean when they insist in-
tentional discrimination based on homosexuality or
transgender status isn’t intentional discrimination based
on sex? Maybe the employers mean they don’t intend to
harm one sex or the other as a class. But as should be clear
by now, the statute focuses on discrimination against indi-
viduals, not groups. Alternatively, the employers may
mean that they don’t perceive themselves as motivated by
a desire to discriminate based on sex. But nothing in Title
VII turns on the employer’s labels or any further intentions
(or motivations) for its conduct beyond sex discrimination.
In Manhart, the employer intentionally required women to
make higher pension contributions only to fulfill the further
purpose of making things more equitable between men and
women as groups. In Phillips, the employer may have per-
ceived itself as discriminating based on motherhood, not
sex, given that its hiring policies as a whole favored women.
But in both cases, the Court set all this aside as irrelevant.
The employers’ policies involved intentional discrimination
18 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

because of sex, and Title VII liability necessarily followed.
 Aren’t these cases different, the employers ask, given
that an employer could refuse to hire a gay or transgender
individual without ever learning the applicant’s sex? Sup-
pose an employer asked homosexual or transgender appli-
cants to tick a box on its application form. The employer
then had someone else redact any information that could be
used to discern sex. The resulting applications would dis-
close which individuals are homosexual or transgender
without revealing whether they also happen to be men or
women. Doesn’t that possibility indicate that the em-
ployer’s discrimination against homosexual or transgender
persons cannot be sex discrimination?
 No, it doesn’t. Even in this example, the individual ap-
plicant’s sex still weighs as a factor in the employer’s deci-
sion. Change the hypothetical ever so slightly and its flaws
become apparent. Suppose an employer’s application form
offered a single box to check if the applicant is either black
or Catholic. If the employer refuses to hire anyone who
checks that box, would we conclude the employer has com-
plied with Title VII, so long as it studiously avoids learning
any particular applicant’s race or religion? Of course not:
By intentionally setting out a rule that makes hiring turn
on race or religion, the employer violates the law, whatever
he might know or not know about individual applicants.
 The same holds here. There is no way for an applicant to
decide whether to check the homosexual or transgender box
without considering sex. To see why, imagine an applicant
doesn’t know what the words homosexual or transgender
mean. Then try writing out instructions for who should
check the box without using the words man, woman, or sex
(or some synonym). It can’t be done. Likewise, there is no
way an employer can discriminate against those who check
the homosexual or transgender box without discriminating
in part because of an applicant’s sex. By discriminating
against homosexuals, the employer intentionally penalizes
 Cite as: 590 U. S. ____ (2020) 19

 Opinion of the Court

men for being attracted to men and women for being at-
tracted to women. By discriminating against transgender
persons, the employer unavoidably discriminates against
persons with one sex identified at birth and another today.
Any way you slice it, the employer intentionally refuses to
hire applicants in part because of the affected individuals’
sex, even if it never learns any applicant’s sex.
 Next, the employers turn to Title VII’s list of protected
characteristics—race, color, religion, sex, and national
origin. Because homosexuality and transgender status
can’t be found on that list and because they are conceptu-
ally distinct from sex, the employers reason, they are im-
plicitly excluded from Title VII’s reach. Put another way, if
Congress had wanted to address these matters in Title VII,
it would have referenced them specifically. Cf. post, at 7–8
(ALITO, J., dissenting); post, at 13–15 (KAVANAUGH, J., dis-
senting).
 But that much does not follow. We agree that homosex-
uality and transgender status are distinct concepts from
sex. But, as we’ve seen, discrimination based on homosex-
uality or transgender status necessarily entails discrimina-
tion based on sex; the first cannot happen without the sec-
ond. Nor is there any such thing as a “canon of donut holes,”
in which Congress’s failure to speak directly to a specific
case that falls within a more general statutory rule creates
a tacit exception. Instead, when Congress chooses not to
include any exceptions to a broad rule, courts apply the
broad rule. And that is exactly how this Court has always
approached Title VII. “Sexual harassment” is conceptually
distinct from sex discrimination, but it can fall within Title
VII’s sweep. Oncale, 523 U. S., at 79–80. Same with “moth-
erhood discrimination.” See Phillips, 400 U. S., at 544 .
Would the employers have us reverse those cases on the
theory that Congress could have spoken to those problems
more specifically? Of course not. As enacted, Title VII pro-
hibits all forms of discrimination because of sex, however
20 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

they may manifest themselves or whatever other labels
might attach to them.
 The employers try the same point another way. Since
1964, they observe, Congress has considered several pro-
posals to add sexual orientation to Title VII’s list of pro-
tected characteristics, but no such amendment has become
law. Meanwhile, Congress has enacted other statutes ad-
dressing other topics that do discuss sexual orientation.
This postenactment legislative history, they urge, should
tell us something. Cf. post, at 2, 42–43 (ALITO, J., dissent-
ing); post, at 4, 15–16 (KAVANAUGH, J., dissenting).
 But what? There’s no authoritative evidence explaining
why later Congresses adopted other laws referencing sex-
ual orientation but didn’t amend this one. Maybe some in
the later legislatures understood the impact Title VII’s
broad language already promised for cases like ours and
didn’t think a revision needed. Maybe others knew about
its impact but hoped no one else would notice. Maybe still
others, occupied by other concerns, didn’t consider the issue
at all. All we can know for certain is that speculation about
why a later Congress declined to adopt new legislation of-
fers a “particularly dangerous” basis on which to rest an in-
terpretation of an existing law a different and earlier Con-
gress did adopt. Pension Benefit Guaranty Corporation v.
LTV Corp., 496 U. S. 633, 650 (1990); see also United States
v. Wells, 519 U. S. 482, 496 (1997); Sullivan v. Finkelstein,
 496 U. S. 617, 632 (1990) (Scalia, J., concurring) (“Argu-
ments based on subsequent legislative history . . . should
not be taken seriously, not even in a footnote”).
 That leaves the employers to seek a different sort of ex-
ception. Maybe the traditional and simple but-for causa-
tion test should apply in all other Title VII cases, but it just
doesn’t work when it comes to cases involving homosexual
and transgender employees. The test is too blunt to capture
the nuances here. The employers illustrate their concern
with an example. When we apply the simple test to Mr.
 Cite as: 590 U. S. ____ (2020) 21

 Opinion of the Court

Bostock—asking whether Mr. Bostock, a man attracted to
other men, would have been fired had he been a woman—
we don’t just change his sex. Along the way, we change his
sexual orientation too (from homosexual to heterosexual).
If the aim is to isolate whether a plaintiff ’s sex caused the
dismissal, the employers stress, we must hold sexual orien-
tation constant—meaning we need to change both his sex
and the sex to which he is attracted. So for Mr. Bostock,
the question should be whether he would’ve been fired if he
were a woman attracted to women. And because his em-
ployer would have been as quick to fire a lesbian as it was
a gay man, the employers conclude, no Title VII violation
has occurred.
 While the explanation is new, the mistakes are the same.
The employers might be onto something if Title VII only en-
sured equal treatment between groups of men and women
or if the statute applied only when sex is the sole or primary
reason for an employer’s challenged adverse employment
action. But both of these premises are mistaken. Title VII’s
plain terms and our precedents don’t care if an employer
treats men and women comparably as groups; an employer
who fires both lesbians and gay men equally doesn’t dimin-
ish but doubles its liability. Just cast a glance back to Man-
hart, where it was no defense that the employer sought to
equalize pension contributions based on life expectancy.
Nor does the statute care if other factors besides sex con-
tribute to an employer’s discharge decision. Mr. Bostock’s
employer might have decided to fire him only because of the
confluence of two factors, his sex and the sex to which he is
attracted. But exactly the same might have been said in
Phillips, where motherhood was the added variable.
 Still, the employers insist, something seems different
here. Unlike certain other employment policies this Court
has addressed that harmed only women or only men, the
employers’ policies in the cases before us have the same ad-
verse consequences for men and women. How could sex be
22 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

necessary to the result if a member of the opposite sex
might face the same outcome from the same policy?
 What the employers see as unique isn’t even unusual. Of-
ten in life and law two but-for factors combine to yield a
result that could have also occurred in some other way. Im-
agine that it’s a nice day outside and your house is too
warm, so you decide to open the window. Both the cool tem-
perature outside and the heat inside are but-for causes of
your choice to open the window. That doesn’t change just
because you also would have opened the window had it been
warm outside and cold inside. In either case, no one would
deny that the window is open “because of ” the outside tem-
perature. Our cases are much the same. So, for example,
when it comes to homosexual employees, male sex and at-
traction to men are but-for factors that can combine to get
them fired. The fact that female sex and attraction to
women can also get an employee fired does no more than
show the same outcome can be achieved through the com-
bination of different factors. In either case, though, sex
plays an essential but-for role.
 At bottom, the employers’ argument unavoidably comes
down to a suggestion that sex must be the sole or primary
cause of an adverse employment action for Title VII liability
to follow. And, as we’ve seen, that suggestion is at odds
with everything we know about the statute. Consider an
employer eager to revive the workplace gender roles of the
1950s. He enforces a policy that he will hire only men as
mechanics and only women as secretaries. When a quali-
fied woman applies for a mechanic position and is denied,
the “simple test” immediately spots the discrimination: A
qualified man would have been given the job, so sex was a
but-for cause of the employer’s refusal to hire. But like the
employers before us today, this employer would say not so
fast. By comparing the woman who applied to be a me-
chanic to a man who applied to be a mechanic, we’ve quietly
 Cite as: 590 U. S. ____ (2020) 23

 Opinion of the Court

changed two things: the applicant’s sex and her trait of fail-
ing to conform to 1950s gender roles. The “simple test” thus
overlooks that it is really the applicant’s bucking of 1950s
gender roles, not her sex, doing the work. So we need to
hold that second trait constant: Instead of comparing the
disappointed female applicant to a man who applied for the
same position, the employer would say, we should compare
her to a man who applied to be a secretary. And because
that jobseeker would be refused too, this must not be sex
discrimination.
 No one thinks that, so the employers must scramble to
justify deploying a stricter causation test for use only in
cases involving discrimination based on sexual orientation
or transgender status. Such a rule would create a curious
discontinuity in our case law, to put it mildly. Employer
hires based on sexual stereotypes? Simple test. Employer
sets pension contributions based on sex? Simple test. Em-
ployer fires men who do not behave in a sufficiently mascu-
line way around the office? Simple test. But when that
same employer discriminates against women who are at-
tracted to women, or persons identified at birth as women
who later identify as men, we suddenly roll out a new and
more rigorous standard? Why are these reasons for taking
sex into account different from all the rest? Title VII’s text
can offer no answer.
 B
 Ultimately, the employers are forced to abandon the stat-
utory text and precedent altogether and appeal to assump-
tions and policy. Most pointedly, they contend that few in
1964 would have expected Title VII to apply to discrimina-
tion against homosexual and transgender persons. And
whatever the text and our precedent indicate, they say,
shouldn’t this fact cause us to pause before recognizing lia-
bility?
 It might be tempting to reject this argument out of hand.
24 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

This Court has explained many times over many years that,
when the meaning of the statute’s terms is plain, our job is
at an end. The people are entitled to rely on the law as
written, without fearing that courts might disregard its
plain terms based on some extratextual consideration. See,
e.g., Carcieri v. Salazar, 555 U. S. 379, 387 (2009); Connect-
icut Nat. Bank v. Germain, 503 U. S. 249 , 253–254 (1992);
Rubin v. United States, 449 U. S. 424, 430 (1981). Of
course, some Members of this Court have consulted legisla-
tive history when interpreting ambiguous statutory lan-
guage. Cf. post, at 40 (ALITO, J., dissenting). But that has
no bearing here. “Legislative history, for those who take it
into account, is meant to clear up ambiguity, not create it.”
Milner v. Department of Navy, 562 U. S. 562 , 574 (2011).
And as we have seen, no ambiguity exists about how Title
VII’s terms apply to the facts before us. To be sure, the
statute’s application in these cases reaches “beyond the
principal evil” legislators may have intended or expected to
address. Oncale, 523 U. S., at 79 . But “ ‘the fact that [a
statute] has been applied in situations not expressly antic-
ipated by Congress’ ” does not demonstrate ambiguity; in-
stead, it simply “ ‘demonstrates [the] breadth’ ” of a legisla-
tive command. Sedima, S. P. R. L. v. Imrex Co., 473 U. S.
479, 499 (1985). And “it is ultimately the provisions of ”
those legislative commands “rather than the principal con-
cerns of our legislators by which we are governed.” Oncale,
 523 U. S., at 79 ; see also A. Scalia & B. Garner, Reading
Law: The Interpretation of Legal Texts 101 (2012) (noting
that unexpected applications of broad language reflect only
Congress’s “presumed point [to] produce general coverage—
not to leave room for courts to recognize ad hoc exceptions”).
 Still, while legislative history can never defeat unambig-
uous statutory text, historical sources can be useful for a
different purpose: Because the law’s ordinary meaning at
the time of enactment usually governs, we must be sensi-
tive to the possibility a statutory term that means one thing
 Cite as: 590 U. S. ____ (2020) 25

 Opinion of the Court

today or in one context might have meant something else at
the time of its adoption or might mean something different
in another context. And we must be attuned to the possi-
bility that a statutory phrase ordinarily bears a different
meaning than the terms do when viewed individually or lit-
erally. To ferret out such shifts in linguistic usage or subtle
distinctions between literal and ordinary meaning, this
Court has sometimes consulted the understandings of the
law’s drafters as some (not always conclusive) evidence.
For example, in the context of the National Motor Vehicle
Theft Act, this Court admitted that the term “vehicle” in
1931 could literally mean “a conveyance working on land,
water or air.” McBoyle v. United States, 283 U. S. 25, 26 
(1931). But given contextual clues and “everyday speech”
at the time of the Act’s adoption in 1919, this Court con-
cluded that “vehicles” in that statute included only things
“moving on land,” not airplanes too. Ibid. Similarly, in New
Prime, we held that, while the term “contracts of employ-
ment” today might seem to encompass only contracts with
employees, at the time of the statute’s adoption the phrase
was ordinarily understood to cover contracts with inde-
pendent contractors as well. 586 U. S., at ___–___ (slip op.,
at 6–9). Cf. post, at 7–8 (KAVANAUGH, J., dissenting)
(providing additional examples).
 The employers, however, advocate nothing like that here.
They do not seek to use historical sources to illustrate that
the meaning of any of Title VII’s language has changed
since 1964 or that the statute’s terms, whether viewed in-
dividually or as a whole, ordinarily carried some message
we have missed. To the contrary, as we have seen, the em-
ployers agree with our understanding of all the statutory
language—“discriminate against any individual . . . be-
cause of such individual’s . . . sex.” Nor do the competing
dissents offer an alternative account about what these
terms mean either when viewed individually or in the ag-
26 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

gregate. Rather than suggesting that the statutory lan-
guage bears some other meaning, the employers and dis-
sents merely suggest that, because few in 1964 expected to-
day’s result, we should not dare to admit that it follows
ineluctably from the statutory text. When a new applica-
tion emerges that is both unexpected and important, they
would seemingly have us merely point out the question, re-
fer the subject back to Congress, and decline to enforce the
plain terms of the law in the meantime.
 That is exactly the sort of reasoning this Court has long
rejected. Admittedly, the employers take pains to couch
their argument in terms of seeking to honor the statute’s
“expected applications” rather than vindicate its “legisla-
tive intent.” But the concepts are closely related. One could
easily contend that legislators only intended expected ap-
plications or that a statute’s purpose is limited to achieving
applications foreseen at the time of enactment. However
framed, the employer’s logic impermissibly seeks to dis-
place the plain meaning of the law in favor of something
lying beyond it.
 If anything, the employers’ new framing may only add
new problems. The employers assert that “no one” in 1964
or for some time after would have anticipated today’s result.
But is that really true? Not long after the law’s passage,
gay and transgender employees began filing Title VII com-
plaints, so at least some people foresaw this potential appli-
cation. See, e.g., Smith v. Liberty Mut. Ins. Co., 395 F.
Supp. 1098, 1099 (ND Ga. 1975) (addressing claim from
1969); Holloway v. Arthur Andersen & Co., 566 F. 2d 659,
661 (CA9 1977) (addressing claim from 1974). And less
than a decade after Title VII’s passage, during debates over
the Equal Rights Amendment, others counseled that its
language—which was strikingly similar to Title VII’s—
might also protect homosexuals from discrimination. See,
e.g., Note, The Legality of Homosexual Marriage, 82 Yale L.
J. 573, 583–584 (1973).

 Opinion of the Court

 Why isn’t that enough to demonstrate that today’s result
isn’t totally unexpected? How many people have to foresee
the application for it to qualify as “expected”? Do we look
only at the moment the statute was enacted, or do we allow
some time for the implications of a new statute to be worked
out? Should we consider the expectations of those who had
no reason to give a particular application any thought or
only those with reason to think about the question? How
do we account for those who change their minds over time,
after learning new facts or hearing a new argument? How
specifically or generally should we frame the “application”
at issue? None of these questions have obvious answers,
and the employers don’t propose any.
 One could also reasonably fear that objections about un-
expected applications will not be deployed neutrally. Often
lurking just behind such objections resides a cynicism that
Congress could not possibly have meant to protect a disfa-
vored group. Take this Court’s encounter with the Ameri-
cans with Disabilities Act’s directive that no “ ‘public en-
tity’ ” can discriminate against any “ ‘qualified individual
with a disability.’ ” Pennsylvania Dept. of Corrections v.
Yeskey, 524 U. S. 206, 208 (1998). Congress, of course,
didn’t list every public entity the statute would apply to.
And no one batted an eye at its application to, say, post of-
fices. But when the statute was applied to prisons, curi-
ously, some demanded a closer look: Pennsylvania argued
that “Congress did not ‘envisio[n] that the ADA would be
applied to state prisoners.’ ” Id., at 211–212. This Court
emphatically rejected that view, explaining that, “in the
context of an unambiguous statutory text,” whether a spe-
cific application was anticipated by Congress “is irrele-
vant.” Id., at 212 . As Yeskey and today’s cases exemplify,
applying protective laws to groups that were politically un-
popular at the time of the law’s passage—whether prison-
ers in the 1990s or homosexual and transgender employees
28 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

in the 1960s—often may be seen as unexpected. But to re-
fuse enforcement just because of that, because the parties
before us happened to be unpopular at the time of the law’s
passage, would not only require us to abandon our role as
interpreters of statutes; it would tilt the scales of justice in
favor of the strong or popular and neglect the promise that
all persons are entitled to the benefit of the law’s terms. Cf.
post, at 28–35 (ALITO, J., dissenting); post, at 21–22
(KAVANAUGH, J., dissenting).
 The employer’s position also proves too much. If we ap-
plied Title VII’s plain text only to applications some (yet-to-
be-determined) group expected in 1964, we’d have more
than a little law to overturn. Start with Oncale. How many
people in 1964 could have expected that the law would turn
out to protect male employees? Let alone to protect them
from harassment by other male employees? As we acknowl-
edged at the time, “male-on-male sexual harassment in the
workplace was assuredly not the principal evil Congress
was concerned with when it enacted Title VII.” 523 U. S.,
at 79 . Yet the Court did not hesitate to recognize that Title
VII’s plain terms forbade it. Under the employer’s logic, it
would seem this was a mistake.
 That’s just the beginning of the law we would have to un-
ravel. As one Equal Employment Opportunity Commission
(EEOC) Commissioner observed shortly after the law’s pas-
sage, the words of “ ‘the sex provision of Title VII [are] diffi-
cult to . . . control.’ ” Franklin, Inventing the “Traditional
Concept” of Sex Discrimination, 125 Harv. L. Rev. 1307 ,
1338 (2012) (quoting Federal Mediation Service To Play
Role in Implementing Title VII, [1965–1968 Transfer
Binder] CCH Employment Practices ¶8046, p. 6074). The
“difficult[y]” may owe something to the initial proponent of
the sex discrimination rule in Title VII, Representative
Howard Smith. On some accounts, the congressman may
have wanted (or at least was indifferent to the possibility
 Cite as: 590 U. S. ____ (2020) 29

 Opinion of the Court

of ) broad language with wide-ranging effect. Not neces-
sarily because he was interested in rooting out sex discrim-
ination in all its forms, but because he may have hoped to
scuttle the whole Civil Rights Act and thought that adding
language covering sex discrimination would serve as a poi-
son pill. See C. Whalen & B. Whalen, The Longest Debate:
A Legislative History of the 1964 Civil Rights Act 115–118
(1985). Certainly nothing in the meager legislative history
of this provision suggests it was meant to be read narrowly.
 Whatever his reasons, thanks to the broad language
Representative Smith introduced, many, maybe most, ap-
plications of Title VII’s sex provision were “unanticipated”
at the time of the law’s adoption. In fact, many now-obvious
applications met with heated opposition early on, even
among those tasked with enforcing the law. In the years
immediately following Title VII’s passage, the EEOC offi-
cially opined that listing men’s positions and women’s posi-
tions separately in job postings was simply helpful rather
than discriminatory. Franklin, 125 Harv. L. Rev., at 1340
(citing Press Release, EEOC (Sept. 22, 1965)). Some courts
held that Title VII did not prevent an employer from firing
an employee for refusing his sexual advances. See, e.g.,
Barnes v. Train, 1974 WL 10628 , *1 (D DC, Aug. 9, 1974).
And courts held that a policy against hiring mothers but not
fathers of young children wasn’t discrimination because of
sex. See Phillips v. Martin Marietta Corp., 411 F. 2d 1 (CA5
1969), rev’d, 400 U. S. 542 (1971) (per curiam).
 Over time, though, the breadth of the statutory language
proved too difficult to deny. By the end of the 1960s, the
EEOC reversed its stance on sex-segregated job advertis-
ing. See Franklin, 125 Harv. L. Rev., at 1345. In 1971, this
Court held that treating women with children differently
from men with children violated Title VII. Phillips, 400
U. S., at 544 . And by the late 1970s, courts began to recog-
nize that sexual harassment can sometimes amount to sex
discrimination. See, e.g., Barnes v. Costle, 561 F. 2d 983 ,
30 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

990 (CADC 1977). While to the modern eye each of these
examples may seem “plainly [to] constitut[e] discrimination
because of biological sex,” post, at 38 (ALITO, J., dissenting),
all were hotly contested for years following Title VII’s en-
actment. And as with the discrimination we consider today,
many federal judges long accepted interpretations of Title
VII that excluded these situations. Cf. post, at 21–22
(KAVANAUGH, J., dissenting) (highlighting that certain
lower courts have rejected Title VII claims based on homo-
sexuality and transgender status). Would the employers
have us undo every one of these unexpected applications
too?
 The weighty implications of the employers’ argument
from expectations also reveal why they cannot hide behind
the no-elephants-in-mouseholes canon. That canon recog-
nizes that Congress “does not alter the fundamental details
of a regulatory scheme in vague terms or ancillary provi-
sions.” Whitman v. American Trucking Assns., Inc., 531
U. S. 457, 468 (2001). But it has no relevance here. We
can’t deny that today’s holding—that employers are prohib-
ited from firing employees on the basis of homosexuality or
transgender status—is an elephant. But where’s the
mousehole? Title VII’s prohibition of sex discrimination in
employment is a major piece of federal civil rights legisla-
tion. It is written in starkly broad terms. It has repeatedly
produced unexpected applications, at least in the view of
those on the receiving end of them. Congress’s key drafting
choices—to focus on discrimination against individuals and
not merely between groups and to hold employers liable
whenever sex is a but-for cause of the plaintiff ’s injuries—
virtually guaranteed that unexpected applications would
emerge over time. This elephant has never hidden in a
mousehole; it has been standing before us all along.
 With that, the employers are left to abandon their con-
cern for expected applications and fall back to the last line
 Cite as: 590 U. S. ____ (2020) 31

 Opinion of the Court

of defense for all failing statutory interpretation argu-
ments: naked policy appeals. If we were to apply the stat-
ute’s plain language, they complain, any number of unde-
sirable policy consequences would follow. Cf. post, at 44–54
(ALITO, J., dissenting). Gone here is any pretense of statu-
tory interpretation; all that’s left is a suggestion we should
proceed without the law’s guidance to do as we think best.
But that’s an invitation no court should ever take up. The
place to make new legislation, or address unwanted conse-
quences of old legislation, lies in Congress. When it comes
to statutory interpretation, our role is limited to applying
the law’s demands as faithfully as we can in the cases that
come before us. As judges we possess no special expertise
or authority to declare for ourselves what a self-governing
people should consider just or wise. And the same judicial
humility that requires us to refrain from adding to statutes
requires us to refrain from diminishing them.
 What are these consequences anyway? The employers
worry that our decision will sweep beyond Title VII to other
federal or state laws that prohibit sex discrimination. And,
under Title VII itself, they say sex-segregated bathrooms,
locker rooms, and dress codes will prove unsustainable af-
ter our decision today. But none of these other laws are
before us; we have not had the benefit of adversarial testing
about the meaning of their terms, and we do not prejudge
any such question today. Under Title VII, too, we do not
purport to address bathrooms, locker rooms, or anything
else of the kind. The only question before us is whether an
employer who fires someone simply for being homosexual
or transgender has discharged or otherwise discriminated
against that individual “because of such individual’s sex.”
As used in Title VII, the term “ ‘discriminate against’ ” refers
to “distinctions or differences in treatment that injure pro-
tected individuals.” Burlington N. & S. F. R., 548 U. S., at
59 . Firing employees because of a statutorily protected
trait surely counts. Whether other policies and practices
32 BOSTOCK v. CLAYTON COUNTY

 Opinion of the Court

might or might not qualify as unlawful discrimination or
find justifications under other provisions of Title VII are
questions for future cases, not these.
 Separately, the employers fear that complying with Title
VII’s requirement in cases like ours may require some em-
ployers to violate their religious convictions. We are also
deeply concerned with preserving the promise of the free
exercise of religion enshrined in our Constitution; that
guarantee lies at the heart of our pluralistic society. But
worries about how Title VII may intersect with religious lib-
erties are nothing new; they even predate the statute’s pas-
sage. As a result of its deliberations in adopting the law,
Congress included an express statutory exception for reli-
gious organizations. §2000e–1(a). This Court has also rec-
ognized that the First Amendment can bar the application
of employment discrimination laws “to claims concerning
the employment relationship between a religious institu-
tion and its ministers.” Hosanna-Tabor Evangelical Lu-
theran Church and School v. EEOC, 565 U. S. 171, 188 
(2012). And Congress has gone a step further yet in the
Religious Freedom Restoration Act of 1993 (RFRA), 107
Stat. 1488 , codified at 42 U. S. C. §2000bb et seq. That stat-
ute prohibits the federal government from substantially
burdening a person’s exercise of religion unless it demon-
strates that doing so both furthers a compelling governmen-
tal interest and represents the least restrictive means of
furthering that interest. §2000bb–1. Because RFRA oper-
ates as a kind of super statute, displacing the normal oper-
ation of other federal laws, it might supersede Title VII’s
commands in appropriate cases. See §2000bb–3.
 But how these doctrines protecting religious liberty inter-
act with Title VII are questions for future cases too. Harris
Funeral Homes did unsuccessfully pursue a RFRA-based
defense in the proceedings below. In its certiorari petition,
however, the company declined to seek review of that ad-
verse decision, and no other religious liberty claim is now
 Cite as: 590 U. S. ____ (2020) 33

 Opinion of the Court

before us. So while other employers in other cases may
raise free exercise arguments that merit careful considera-
tion, none of the employers before us today represent in this
Court that compliance with Title VII will infringe their own
religious liberties in any way.
 *
 Some of those who supported adding language to Title VII
to ban sex discrimination may have hoped it would derail
the entire Civil Rights Act. Yet, contrary to those inten-
tions, the bill became law. Since then, Title VII’s effects
have unfolded with far-reaching consequences, some likely
beyond what many in Congress or elsewhere expected.
 But none of this helps decide today’s cases. Ours is a so-
ciety of written laws. Judges are not free to overlook plain
statutory commands on the strength of nothing more than
suppositions about intentions or guesswork about expecta-
tions. In Title VII, Congress adopted broad language mak-
ing it illegal for an employer to rely on an employee’s sex
when deciding to fire that employee. We do not hesitate to
recognize today a necessary consequence of that legislative
choice: An employer who fires an individual merely for be-
ing gay or transgender defies the law.

 ALITO, J., dissenting

 Title VII of the Civil Rights Act of 1964 prohibits employ-
ment discrimination on any of five specified grounds: “race,
color, religion, sex, [and] national origin.” 42 U. S. C.
§2000e–2(a)(1). Neither “sexual orientation” nor “gender
identity” appears on that list. For the past 45 years, bills
have been introduced in Congress to add “sexual orienta-
tion” to the list,1 and in recent years, bills have included
“gender identity” as well.2 But to date, none has passed
both Houses.
 Last year, the House of Representatives passed a bill that
would amend Title VII by defining sex discrimination to in-
clude both “sexual orientation” and “gender identity,” H. R.
5, 116th Cong., 1st Sess. (2019), but the bill has stalled in
the Senate. An alternative bill, H. R. 5331, 116th Cong.,
1st Sess. (2019), would add similar prohibitions but con-
tains provisions to protect religious liberty.3 This bill re-
mains before a House Subcommittee.
 Because no such amendment of Title VII has been en-
acted in accordance with the requirements in the Constitu-
tion (passage in both Houses and presentment to the Pres-
ident, Art. I, §7, cl. 2), Title VII’s prohibition of

discrimination because of “sex” still means what it has al-
ways meant. But the Court is not deterred by these consti-
tutional niceties. Usurping the constitutional authority of
the other branches, the Court has essentially taken H. R.
5’s provision on employment discrimination and issued it
under the guise of statutory interpretation.4 A more brazen
abuse of our authority to interpret statutes is hard to recall.
 The Court tries to convince readers that it is merely en-
forcing the terms of the statute, but that is preposterous.
Even as understood today, the concept of discrimination be-
cause of “sex” is different from discrimination because of
“sexual orientation” or “gender identity.” And in any event,
our duty is to interpret statutory terms to “mean what they
conveyed to reasonable people at the time they were writ-
ten.” A. Scalia & B. Garner, Reading Law: The Interpreta-
tion of Legal Texts 16 (2012) (emphasis added). If every
single living American had been surveyed in 1964, it would
have been hard to find any who thought that discrimination
because of sex meant discrimination because of sexual ori-
entation––not to mention gender identity, a concept that
was essentially unknown at the time.
 The Court attempts to pass off its decision as the inevita-
ble product of the textualist school of statutory interpreta-
tion championed by our late colleague Justice Scalia, but no
one should be fooled. The Court’s opinion is like a pirate
ship. It sails under a textualist flag, but what it actually
represents is a theory of statutory interpretation that Jus-
tice Scalia excoriated––the theory that courts should “up-
date” old statutes so that they better reflect the current val-
ues of society. See A. Scalia, A Matter of Interpretation 22

(1997). If the Court finds it appropriate to adopt this the-
ory, it should own up to what it is doing.5
 Many will applaud today’s decision because they agree on
policy grounds with the Court’s updating of Title VII. But
the question in these cases is not whether discrimination
because of sexual orientation or gender identity should be
outlawed. The question is whether Congress did that in
1964.
 It indisputably did not.
 I
 A
 Title VII, as noted, prohibits discrimination “because of
. . . sex,” §2000e–2(a)(1), and in 1964, it was as clear as clear
could be that this meant discrimination because of the ge-
netic and anatomical characteristics that men and women
have at the time of birth. Determined searching has not
found a single dictionary from that time that defined “sex”
to mean sexual orientation, gender identity, or
“transgender status.”6 Ante, at 2. (Appendix A, infra, to

——————
 5 That is what Judge Posner did in the Seventh Circuit case holding

that Title VII prohibits discrimination because of sexual orientation. See
Hively v. Ivy Tech Community College of Ind., 853 F. 3d 339 (2017) (en
banc). Judge Posner agreed with that result but wrote:
 “I would prefer to see us acknowledge openly that today we, who are
judges rather than members of Congress, are imposing on a half-century-
old statute a meaning of ‘sex discrimination’ that the Congress that en-
acted it would not have accepted.” Id., at 357 (concurring opinion) (em-
phasis added).
 6 The Court does not define what it means by “transgender status,” but

the American Psychological Association describes “transgender” as “[a]n
umbrella term encompassing those whose gender identities or gender
roles differ from those typically associated with the sex they were as-
signed at birth.” A Glossary: Defining Transgender Terms, 49 Monitor
on Psychology 32 (Sept. 2018), https://www.apa.org/monitor/2018/09/ce-
corner-glossary. It defines “gender identity” as “[a]n internal sense of
being male, female or something else, which may or may not correspond

 ALITO, J., dissenting

this opinion includes the full definitions of “sex” in the un-
abridged dictionaries in use in the 1960s.)
 In all those dictionaries, the primary definition of “sex”
was essentially the same as that in the then-most recent
edition of Webster’s New International Dictionary 2296
(def. 1) (2d ed. 1953): “[o]ne of the two divisions of organisms
formed on the distinction of male and female.” See also
American Heritage Dictionary 1187 (def. 1(a)) (1969) (“The
property or quality by which organisms are classified ac-
cording to their reproductive functions”); Random House
Dictionary of the English Language 1307 (def. 1) (1966)
(Random House Dictionary) (“the fact or character of being
either male or female”); 9 Oxford English Dictionary 577
(def. 1) (1933) (“Either of the two divisions of organic beings
distinguished as male and female respectively”).
 The Court does not dispute that this is what “sex” means
in Title VII, although it coyly suggests that there is at least
some support for a different and potentially relevant defi-
nition. Ante, at 5. (I address alternative definitions below.
See Part I–B–3, infra.) But the Court declines to stand on
that ground and instead “proceed[s] on the assumption that
‘sex’ . . . refer[s] only to biological distinctions between male
and female.” Ante, at 5.
 If that is so, it should be perfectly clear that Title VII does
not reach discrimination because of sexual orientation or
gender identity. If “sex” in Title VII means biologically
male or female, then discrimination because of sex means
discrimination because the person in question is biologi-
cally male or biologically female, not because that person is
sexually attracted to members of the same sex or identifies
as a member of a particular gender.
 How then does the Court claim to avoid that conclusion?

to an individual’s sex assigned at birth or sex characteristics.” Ibid. Un-
der these definitions, there is no apparent difference between discrimi-
nation because of transgender status and discrimination because of gen-
der identity.
6 BOSTOCK v. CLAYTON COUNTY

 ALITO, J., dissenting

The Court tries to cloud the issue by spending many pages
discussing matters that are beside the point. The Court ob-
serves that a Title VII plaintiff need not show that “sex”
was the sole or primary motive for a challenged employ-
ment decision or its sole or primary cause; that Title VII is
limited to discrimination with respect to a list of specified
actions (such as hiring, firing, etc.); and that Title VII
protects individual rights, not group rights. See ante, at 5–
9, 11.
 All that is true, but so what? In cases like those before
us, a plaintiff must show that sex was a “motivating factor”
in the challenged employment action, 42 U. S. C. §2000e–
2(m), so the question we must decide comes down to this: if
an individual employee or applicant for employment shows
that his or her sexual orientation or gender identity was a
“motivating factor” in a hiring or discharge decision, for ex-
ample, is that enough to establish that the employer dis-
criminated “because of . . . sex”? Or, to put the same ques-
tion in different terms, if an employer takes an employment
action solely because of the sexual orientation or gender
identity of an employee or applicant, has that employer nec-
essarily discriminated because of biological sex?
 The answers to those questions must be no, unless dis-
crimination because of sexual orientation or gender identity
inherently constitutes discrimination because of sex. The
Court attempts to prove that point, and it argues, not
merely that the terms of Title VII can be interpreted that
way but that they cannot reasonably be interpreted any
other way. According to the Court, the text is unambiguous.
See ante, at 24, 27, 30.
 The arrogance of this argument is breathtaking. As I will
show, there is not a shred of evidence that any Member of
Congress interpreted the statutory text that way when Ti-
tle VII was enacted. See Part III–B, infra. But the Court
apparently thinks that this was because the Members were
not “smart enough to realize” what its language means.

ingly has the same opinion about our colleagues on the
Courts of Appeals, because until 2017, every single Court of
Appeals to consider the question interpreted Title VII’s pro-
hibition against sex discrimination to mean discrimination
on the basis of biological sex. See Part III–C, infra. And for
good measure, the Court’s conclusion that Title VII unam-
biguously reaches discrimination on the basis of sexual ori-
entation and gender identity necessarily means that the
EEOC failed to see the obvious for the first 48 years after
Title VII became law.7 Day in and day out, the Commission
enforced Title VII but did not grasp what discrimination
“because of . . . sex” unambiguously means. See Part III–C,
infra.
 The Court’s argument is not only arrogant, it is wrong. It
fails on its own terms. “Sex,” “sexual orientation,” and “gen-
der identity” are different concepts, as the Court concedes.
Ante, at 19 (“homosexuality and transgender status are dis-
tinct concepts from sex”). And neither “sexual orientation”
nor “gender identity” is tied to either of the two biological
sexes. See ante, at 10 (recognizing that “discrimination on
these bases” does not have “some disparate impact on one
sex or another”). Both men and women may be attracted to
members of the opposite sex, members of the same sex, or
members of both sexes.8 And individuals who are born with

vidual because that person is transgender” violates Title VII in 2012 in
Macy v. Holder, 2012 WL 1435995 , *11 (Apr. 20, 2012), though it earlier
advanced that position in an amicus brief in Federal District Court in
2011, ibid., n. 16. It did not hold that discrimination on the basis of sex-
ual orientation violated Title VII until 2015. See Baldwin v. Foxx, 2015
WL 4397641 (July 15, 2015).

the genes and organs of either biological sex may identify
with a different gender.9
 Using slightly different terms, the Court asserts again
and again that discrimination because of sexual orientation
or gender identity inherently or necessarily entails discrim-
ination because of sex. See ante, at 2 (When an employer
“fires an individual for being homosexual or transgender,”
“[s]ex plays a necessary and undisguisable role in the deci-
sion”); ante, at 9 (“[I]t is impossible to discriminate against
a person for being homosexual or transgender without dis-
criminating against that individual based on sex”); ante, at
11 (“[W]hen an employer discriminates against homosexual
or transgender employees, [the] employer . . . inescapably
intends to rely on sex in its decisionmaking”); ante, at 12
(“For an employer to discriminate against employees for be-
ing homosexual or transgender, the employer must inten-
tionally discriminate against individual men and women in
part because of sex”); ante, at 14 (“When an employer fires
an employee for being homosexual or transgender, it neces-
sarily and intentionally discriminates against that individ-
ual in part because of sex”); ante, at 19 (“[D]iscrimination
based on homosexuality or transgender status necessarily
entails discrimination based on sex”). But repetition of an
assertion does not make it so, and the Court’s repeated as-
sertion is demonstrably untrue.

cause of sexual orientation or gender identity does not in

and of itself entail discrimination because of sex. We can
see this because it is quite possible for an employer to dis-
criminate on those grounds without taking the sex of an in-
dividual applicant or employee into account. An employer
can have a policy that says: “We do not hire gays, lesbians,
or transgender individuals.” And an employer can imple-
ment this policy without paying any attention to or even
knowing the biological sex of gay, lesbian, and transgender
applicants. In fact, at the time of the enactment of Title
VII, the United States military had a blanket policy of re-
fusing to enlist gays or lesbians, and under this policy for
years thereafter, applicants for enlistment were required to
complete a form that asked whether they were “homosex-
ual.” Appendix D, infra, at 88, 101.
 At oral argument, the attorney representing the employ-
ees, a prominent professor of constitutional law, was asked
if there would be discrimination because of sex if an em-
ployer with a blanket policy against hiring gays, lesbians,
and transgender individuals implemented that policy with-
out knowing the biological sex of any job applicants. Her
candid answer was that this would “not” be sex discrimina-
tion.10 And she was right.
 The attorney’s concession was necessary, but it is fatal to
the Court’s interpretation, for if an employer discriminates
against individual applicants or employees without even
knowing whether they are male or female, it is impossible
to argue that the employer intentionally discriminated be-
cause of sex. Contra, ante, at 19. An employer cannot in-
tentionally discriminate on the basis of a characteristic of
which the employer has no knowledge. And if an employer
does not violate Title VII by discriminating on the basis of

sexual orientation or gender identity without knowing the
sex of the affected individuals, there is no reason why the
same employer could not lawfully implement the same pol-
icy even if it knows the sex of these individuals. If an em-
ployer takes an adverse employment action for a perfectly
legitimate reason—for example, because an employee stole
company property—that action is not converted into sex
discrimination simply because the employer knows the em-
ployee’s sex. As explained, a disparate treatment case re-
quires proof of intent—i.e., that the employee’s sex moti-
vated the firing. In short, what this example shows is that
discrimination because of sexual orientation or gender iden-
tity does not inherently or necessarily entail discrimination
because of sex, and for that reason, the Court’s chief argu-
ment collapses.
 Trying to escape the consequences of the attorney’s con-
cession, the Court offers its own hypothetical:
 “Suppose an employer’s application form offered a sin-
 gle box to check if the applicant is either black or Cath-
 olic. If the employer refuses to hire anyone who checks
 that box, would we conclude the employer has complied
 with Title VII, so long as it studiously avoids learning
 any particular applicant’s race or religion? Of course
 not.” Ante, at 18.
 How this hypothetical proves the Court’s point is a mys-
tery. A person who checked that box would presumably be
black, Catholic, or both, and refusing to hire an applicant
because of race or religion is prohibited by Title VII. Re-
jecting applicants who checked a box indicating that they
are homosexual is entirely different because it is impossible
to tell from that answer whether an applicant is male or
female.
 The Court follows this strange hypothetical with an even
stranger argument. The Court argues that an applicant
 Cite as: 590 U. S. ____ (2020) 11

 ALITO, J., dissenting

could not answer the question whether he or she is homo-
sexual without knowing something about sex. If the appli-
cant was unfamiliar with the term “homosexual,” the appli-
cant would have to look it up or ask what the term means.
And because this applicant would have to take into account
his or her sex and that of the persons to whom he or she is
sexually attracted to answer the question, it follows, the
Court reasons, that an employer could not reject this appli-
cant without taking the applicant’s sex into account. See
ante, at 18–19.
 This is illogical. Just because an applicant cannot say
whether he or she is homosexual without knowing his or
her own sex and that of the persons to whom the applicant
is attracted, it does not follow that an employer cannot re-
ject an applicant based on homosexuality without knowing
the applicant’s sex.
 While the Court’s imagined application form proves noth-
ing, another hypothetical case offered by the Court is tell-
ing. But what it proves is not what the Court thinks. The
Court posits:
 “Imagine an employer who has a policy of firing any
 employee known to be homosexual. The employer
 hosts an office holiday party and invites employees to
 bring their spouses. A model employee arrives and in-
 troduces a manager to Susan, the employee’s wife. Will
 that employee be fired? If the policy works as the em-
 ployer intends, the answer depends entirely on
 whether the model employee is a man or a woman.”
 Ante, at 11.
 This example disproves the Court’s argument because it
is perfectly clear that the employer’s motivation in firing
the female employee had nothing to do with that employee’s
sex. The employer presumably knew that this employee
was a woman before she was invited to the fateful party.
Yet the employer, far from holding her biological sex
12 BOSTOCK v. CLAYTON COUNTY

 ALITO, J., dissenting

against her, rated her a “model employee.” At the party,
the employer learned something new, her sexual orienta-
tion, and it was this new information that motivated her
discharge. So this is another example showing that dis-
crimination because of sexual orientation does not inher-
ently involve discrimination because of sex.
 In addition to the failed argument just discussed, the
Court makes two other arguments, more or less in passing.
The first of these is essentially that sexual orientation and
gender identity are closely related to sex. The Court argues
that sexual orientation and gender identity are “inextrica-
bly bound up with sex,” ante, at 10, and that discrimination
on the basis of sexual orientation or gender identity in-
volves the application of “sex-based rules,” ante, at 17. This
is a variant of an argument found in many of the briefs filed
in support of the employees and in the lower court decisions
that agreed with the Court’s interpretation. All these vari-
ants stress that sex, sexual orientation, and gender identity
are related concepts. The Seventh Circuit observed that
“[i]t would require considerable calisthenics to remove ‘sex’
from ‘sexual orientation.’ ” Hively, 853 F. 3d, at 350 .11 The
Second Circuit wrote that sex is necessarily “a factor in sex-
ual orientation” and further concluded that “sexual orien-
tation is a function of sex.” 883 F. 3d 100 , 112–113 (CA2
2018) (en banc). Bostock’s brief and those of amici support-
ing his position contend that sexual orientation is “a sex-
based consideration.”12 Other briefs state that sexual ori-
entation is “a function of sex”13 or is “intrinsically related to

sex.”14 Similarly, Stephens argues that sex and gender
identity are necessarily intertwined: “By definition, a
transgender person is someone who lives and identifies
with a sex different than the sex assigned to the person at
birth.”15
 It is curious to see this argument in an opinion that pur-
ports to apply the purest and highest form of textualism be-
cause the argument effectively amends the statutory text.
Title VII prohibits discrimination because of sex itself, not
everything that is related to, based on, or defined with ref-
erence to, “sex.” Many things are related to sex. Think of
all the nouns other than “orientation” that are commonly
modified by the adjective “sexual.” Some examples yielded
by a quick computer search are “sexual harassment,” “sex-
ual assault, “sexual violence,” “sexual intercourse,” and
“sexual content.”
 Does the Court really think that Title VII prohibits dis-
crimination on all these grounds? Is it unlawful for an em-
ployer to refuse to hire an employee with a record of sexual
harassment in prior jobs? Or a record of sexual assault or
violence?
 To be fair, the Court does not claim that Title VII prohib-
its discrimination because of everything that is related to
sex. The Court draws a distinction between things that are
“inextricably” related and those that are related in “some
vague sense.” Ante, at 10. Apparently the Court would
graft onto Title VII some arbitrary line separating the
things that are related closely enough and those that are
not.16 And it would do this in the name of high textualism.

nores. The statute specifies that the terms “because of sex” and “on the
basis of sex” cover certain conditions that are biologically tied to sex,
14 BOSTOCK v. CLAYTON COUNTY

 ALITO, J., dissenting

 An additional argument made in passing also fights the
text of Title VII and the policy it reflects. The Court pro-
claims that “[a]n individual’s homosexuality or transgender
status is not relevant to employment decisions.” Ante, at 9.
That is the policy view of many people in 2020, and perhaps
Congress would have amended Title VII to implement it if
this Court had not intervened. But that is not the policy
embodied in Title VII in its current form. Title VII prohib-
its discrimination based on five specified grounds, and nei-
ther sexual orientation nor gender identity is on the list. As
long as an employer does not discriminate based on one of
the listed grounds, the employer is free to decide for itself
which characteristics are “relevant to [its] employment de-
cisions.” Ibid. By proclaiming that sexual orientation and
gender identity are “not relevant to employment decisions,”
the Court updates Title VII to reflect what it regards as
2020 values.
 The Court’s remaining argument is based on a hypothet-
ical that the Court finds instructive. In this hypothetical,
an employer has two employees who are “attracted to men,”
and “to the employer’s mind” the two employees are “mate-
rially identical” except that one is a man and the other is a
woman. Ante, at 9 (emphasis added). The Court reasons
that if the employer fires the man but not the woman, the
employer is necessarily motivated by the man’s biological
sex. Ante, at 9–10. After all, if two employees are identical
in every respect but sex, and the employer fires only one,
what other reason could there be?
 The problem with this argument is that the Court loads
the dice. That is so because in the mind of an employer who
does not want to employ individuals who are attracted to

namely, “pregnancy, childbirth, [and] related medical conditions.” 42
U. S. C. §2000e(k). This definition should inform the meaning of “be-
cause of sex” in Title VII more generally. Unlike pregnancy, neither sex-
ual orientation nor gender identity is biologically linked to women or
men.
 Cite as: 590 U. S. ____ (2020) 15

 ALITO, J., dissenting

members of the same sex, these two employees are not ma-
terially identical in every respect but sex. On the contrary,
they differ in another way that the employer thinks is quite
material. And until Title VII is amended to add sexual ori-
entation as a prohibited ground, this is a view that an em-
ployer is permitted to implement. As noted, other than pro-
hibiting discrimination on any of five specified grounds,
“race, color, religion, sex, [and] national origin.” 42 U. S. C.
§2000e–2(a)(1), Title VII allows employers to decide
whether two employees are “materially identical.” Even id-
iosyncratic criteria are permitted; if an employer thinks
that Scorpios make bad employees, the employer can refuse
to hire Scorpios. Such a policy would be unfair and foolish,
but under Title VII, it is permitted. And until Title VII is
amended, so is a policy against employing gays, lesbians, or
transgender individuals.
 Once this is recognized, what we have in the Court’s hy-
pothetical case are two employees who differ in two ways––
sex and sexual orientation––and if the employer fires one
and keeps the other, all that can be inferred is that the em-
ployer was motivated either entirely by sexual orientation,
entirely by sex, or in part by both. We cannot infer with
any certainty, as the hypothetical is apparently meant to
suggest, that the employer was motivated even in part by
sex. The Court harps on the fact that under Title VII a pro-
hibited ground need not be the sole motivation for an ad-
verse employment action, see ante, at 10–11, 14–15, 21, but
its example does not show that sex necessarily played any
part in the employer’s thinking.
 The Court tries to avoid this inescapable conclusion by
arguing that sex is really the only difference between the
two employees. This is so, the Court maintains, because
both employees “are attracted to men.” Ante, at 9–10. Of
course, the employer would couch its objection to the man
differently. It would say that its objection was his sexual
orientation. So this may appear to leave us with a battle of
16 BOSTOCK v. CLAYTON COUNTY

 ALITO, J., dissenting

labels. If the employer’s objection to the male employee is
characterized as attraction to men, it seems that he is just
like the woman in all respects except sex and that the em-
ployer’s disparate treatment must be based on that one dif-
ference. On the other hand, if the employer’s objection is
sexual orientation or homosexuality, the two employees dif-
fer in two respects, and it cannot be inferred that the dis-
parate treatment was due even in part to sex.
 The Court insists that its label is the right one, and that
presumably is why it makes such a point of arguing that an
employer cannot escape liability under Title VII by giving
sex discrimination some other name. See ante, at 14, 17.
That is certainly true, but so is the opposite. Something
that is not sex discrimination cannot be converted into sex
discrimination by slapping on that label. So the Court can-
not prove its point simply by labeling the employer’s objec-
tion as “attract[ion] to men.” Ante, at 9–10. Rather, the
Court needs to show that its label is the correct one.
 And a labeling standoff would not help the Court because
that would mean that the bare text of Title VII does not
unambiguously show that its interpretation is right. The
Court would have no justification for its stubborn refusal to
look any further.
 As it turns out, however, there is no standoff. It can eas-
ily be shown that the employer’s real objection is not “at-
tract[ion] to men” but homosexual orientation.
 In an effort to prove its point, the Court carefully includes
in its example just two employees, a homosexual man and
a heterosexual woman, but suppose we add two more indi-
viduals, a woman who is attracted to women and a man who
is attracted to women. (A large employer will likely have
applicants and employees who fall into all four categories,
and a small employer can potentially have all four as well.)
We now have the four exemplars listed below, with the dis-
charged employees crossed out:
 Cite as: 590 U. S. ____ (2020) 17

 ALITO, J., dissenting

 Man attracted to men
 Woman attracted to men
 Woman attracted to women
 Man attracted to women
 The discharged employees have one thing in common. It
is not biological sex, attraction to men, or attraction to
women. It is attraction to members of their own sex—in a
word, sexual orientation. And that, we can infer, is the em-
ployer’s real motive.
 In sum, the Court’s textual arguments fail on their own
terms. The Court tries to prove that “it is impossible to dis-
criminate against a person for being homosexual or
transgender without discriminating against that individual
based on sex,” ante, at 9, but as has been shown, it is en-
tirely possible for an employer to do just that. “[H]omosex-
uality and transgender status are distinct concepts from
sex,” ante, at 19, and discrimination because of sexual ori-
entation or transgender status does not inherently or nec-
essarily constitute discrimination because of sex. The
Court’s arguments are squarely contrary to the statutory
text.
 But even if the words of Title VII did not definitively re-
fute the Court’s interpretation, that would not justify the
Court’s refusal to consider alternative interpretations. The
Court’s excuse for ignoring everything other than the bare
statutory text is that the text is unambiguous and therefore
no one can reasonably interpret the text in any way other
than the Court does. Unless the Court has met that high
standard, it has no justification for its blinkered approach.
And to say that the Court’s interpretation is the only possi-
ble reading is indefensible.

 Although the Court relies solely on the arguments dis-
cussed above, several other arguments figure prominently

 ALITO, J., dissenting

by or in support of the employees. The Court apparently
finds these arguments unpersuasive, and so do I, but for the
sake of completeness, I will address them briefly.
 1
 One argument, which relies on our decision in Price Wa-
terhouse v. Hopkins, 490 U. S. 228 (1989) (plurality opin-
ion), is that discrimination because of sexual orientation or
gender identity violates Title VII because it constitutes pro-
hibited discrimination on the basis of sex stereotypes. See
883 F. 3d, at 119–123; Hively, 853 F. 3d, at 346 ; 884 F. 3d
560 , 576–577 (CA6 2018). The argument goes like this. Ti-
tle VII prohibits discrimination based on stereotypes about
the way men and women should behave; the belief that a
person should be attracted only to persons of the opposite
sex and the belief that a person should identify with his or
her biological sex are examples of such stereotypes; there-
fore, discrimination on either of these grounds is unlawful.
 This argument fails because it is based on a faulty prem-
ise, namely, that Title VII forbids discrimination based on
sex stereotypes. It does not. It prohibits discrimination be-
cause of “sex,” and the two concepts are not the same. See
Price Waterhouse, 490 U. S., at 251 . That does not mean,
however, that an employee or applicant for employment
cannot prevail by showing that a challenged decision was
based on a sex stereotype. Such evidence is relevant to
prove discrimination because of sex, and it may be convinc-
ing where the trait that is inconsistent with the stereotype
is one that would be tolerated and perhaps even valued in
a person of the opposite sex. See ibid. 
 Much of the plaintiff ’s evidence in Price Waterhouse was
of this nature. The plaintiff was a woman who was passed
over for partnership at an accounting firm, and some of the
adverse comments about her work appeared to criticize her
for being forceful and insufficiently “feminin[e].” Id., at
235–236.

 ALITO, J., dissenting

 The main issue in Price Waterhouse––the proper alloca-
tion of the burdens of proof in a so-called mixed motives Ti-
tle VII case—is not relevant here, but the plurality opinion,
endorsed by four Justices, commented on the issue of sex
stereotypes. The plurality observed that “sex stereotypes
do not inevitably prove that gender played a part in a par-
ticular employment decision” but “can certainly be evidence
that gender played a part.” Id., at 251.17 And the plurality
made it clear that “[t]he plaintiff must show that the em-
ployer actually relied on her gender in making its decision.”
Ibid.
 Plaintiffs who allege that they were treated unfavorably
because of their sexual orientation or gender identity are
not in the same position as the plaintiff in Price Water-
house. In cases involving discrimination based on sexual
orientation or gender identity, the grounds for the em-
ployer’s decision—that individuals should be sexually at-
tracted only to persons of the opposite biological sex or
should identify with their biological sex—apply equally to
men and women. “[H]eterosexuality is not a female stereo-
type; it not a male stereotype; it is not a sex-
specific stereotype at all.” Hively, 853 F. 3d, at 370 (Sykes,
J., dissenting).
 To be sure, there may be cases in which a gay, lesbian, or
transgender individual can make a claim like the one in
Price Waterhouse. That is, there may be cases where traits
or behaviors that some people associate with gays, lesbians,
or transgender individuals are tolerated or valued in per-
sons of one biological sex but not the other. But that is a

 17 Two other Justices concurred in the judgment but did not comment

on the issue of stereotypes. See id., at 258–261 (opinion of White, J.); id., 
at 261–279 (opinion of O’Connor, J.). And Justice Kennedy reiterated on
behalf of the three Justices in dissent that “Title VII creates no independ-
ent cause of action for sex stereotyping,” but he added that “[e]vidence of
use by decisionmakers of sex stereotypes is, of course, quite relevant to
the question of discriminatory intent.” Id., at 294.

different matter.
 2
 A second prominent argument made in support of the re-
sult that the Court now reaches analogizes discrimination
against gays and lesbians to discrimination against a per-
son who is married to or has an intimate relationship with
a person of a different race. Several lower court cases have
held that discrimination on this ground violates Title VII.
See, e.g., Holcomb v. Iona College, 521 F. 3d 130 (CA2 2008);
Parr v. Woodmen of World Life Ins. Co., 791 F. 2d 888 (CA11
1986). And the logic of these decisions, it is argued, applies
equally where an employee or applicant is treated unfavor-
ably because he or she is married to, or has an intimate re-
lationship with, a person of the same sex.
 This argument totally ignores the historically rooted rea-
son why discrimination on the basis of an interracial rela-
tionship constitutes race discrimination. And without tak-
ing history into account, it is not easy to see how the
decisions in question fit the terms of Title VII.
 Recall that Title VII makes it unlawful for an employer
to discriminate against an individual “because of such indi-
vidual’s race.” 42 U. S. C. §2000e–2(a) (emphasis added).
So if an employer is happy to employ whites and blacks but
will not employ any employee in an interracial relationship,
how can it be said that the employer is discriminating
against either whites or blacks “because of such individual’s
race”? This employer would be applying the same rule to
all its employees regardless of their race.
 The answer is that this employer is discriminating on a
ground that history tells us is a core form of race discrimi-
nation.18 “It would require absolute blindness to the history

of racial discrimination in this country not to understand
what is at stake in such cases . . . . A prohibition on ‘race-
mixing’ was . . . grounded in bigotry against a particular
race and was an integral part of preserving the rigid hier-
archical distinction that denominated members of the black
race as inferior to whites.” 883 F. 3d, at 158–159 (Lynch,
J., dissenting).
 Discrimination because of sexual orientation is different.
It cannot be regarded as a form of sex discrimination on the
ground that applies in race cases since discrimination be-
cause of sexual orientation is not historically tied to a pro-
ject that aims to subjugate either men or women. An em-
ployer who discriminates on this ground might be called
“homophobic” or “transphobic,” but not sexist. See Wittmer
v. Phillips 66 Co., 915 F. 3d 328, 338 (CA5 2019) (Ho, J.,
concurring).

 The opinion of the Court intimates that the term “sex”
was not universally understood in 1964 to refer just to the
categories of male and female, see ante, at 5, and while the
Court does not take up any alternative definition as a
ground for its decision, I will say a word on this subject.
 As previously noted, the definitions of “sex” in the una-
bridged dictionaries in use in the 1960s are reproduced in
Appendix A, infra. Anyone who examines those definitions
can see that the primary definition in every one of them re-
fers to the division of living things into two groups, male
and female, based on biology, and most of the definitions
further down the list are the same or very similar. In addi-

 Aside from these, what is there? One definition, “to neck
passionately,” Random House Dictionary 1307 (def. 8), re-
fers to sexual conduct that is not necessarily heterosexual.
But can it be seriously argued that one of the aims of Title
VII is to outlaw employment discrimination against em-
ployees, whether heterosexual or homosexual, who engage
in necking? And even if Title VII had that effect, that is not
what is at issue in cases like those before us.
 That brings us to the two remaining subsidiary defini-
tions, both of which refer to sexual urges or instincts and
their manifestations. See the fourth definition in the Amer-
ican Heritage Dictionary, at 1187 (“the sexual urge or in-
stinct as it manifests itself in behavior”), and the fourth def-
inition in both Webster’s Second and Third (“[p]henomena
of sexual instincts and their manifestations,” Webster’s
New International Dictionary, at 2296 (2d ed.); Webster’s
Third New International Dictionary 2081 (1966)). Since
both of these come after three prior definitions that refer to
men and women, they are most naturally read to have the
same association, and in any event, is it plausible that Title
VII prohibits discrimination based on any sexual urge or
instinct and its manifestations? The urge to rape?
 Viewing all these definitions, the overwhelming impact is
that discrimination because of “sex” was understood during
the era when Title VII was enacted to refer to men and
women. (The same is true of current definitions, which are
reproduced in Appendix B, infra.) This no doubt explains
why neither this Court nor any of the lower courts have
tried to make much of the dictionary definitions of sex just

 II
 A
 So far, I have not looked beyond dictionary definitions of
“sex,” but textualists like Justice Scalia do not confine their
inquiry to the scrutiny of dictionaries. See Manning, Tex-
tualism and the Equity of the Statute, 101 Colum. L. Rev.
1 , 109 (2001). Dictionary definitions are valuable because
they are evidence of what people at the time of a statute’s
enactment would have understood its words to mean. Ibid.
But they are not the only source of relevant evidence, and
what matters in the end is the answer to the question that
the evidence is gathered to resolve: How would the terms of
a statute have been understood by ordinary people at the
time of enactment?
 Justice Scalia was perfectly clear on this point. The
words of a law, he insisted, “mean what they conveyed to
reasonable people at the time.” Reading Law, at 16 (empha-
sis added).20
 Leading proponents of Justice Scalia’s school of textual-
ism have expounded on this principle and explained that it
is grounded on an understanding of the way language
works. As Dean John F. Manning explains, “the meaning
of language depends on the way a linguistic community
uses words and phrases in context.” What Divides Textu-
alists From Purposivists? 106 Colum. L. Rev. 70 , 78 (2006).
“[O]ne can make sense of others’ communications only by
placing them in their appropriate social and linguistic con-
text,” id., at 79–80, and this is no less true of statutes than
any other verbal communications. “[S]tatutes convey
meaning only because members of a relevant linguistic

so determined”).

community apply shared background conventions for un-
derstanding how particular words are used in particular
contexts.” Manning, The Absurdity Doctrine, 116 Harv. L.
Rev. 2387 , 2457 (2003). Therefore, judges should ascribe to
the words of a statute “what a reasonable person conver-
sant with applicable social conventions would have under-
stood them to be adopting.” Manning, 106 Colum. L. Rev.,
at 77. Or, to put the point in slightly different terms, a
judge interpreting a statute should ask “ ‘what one would
ordinarily be understood as saying, given the circumstances
in which one said it.’ ” Manning, 116 Harv. L. Rev., at 2397–
2398.
 Judge Frank Easterbrook has made the same points:
 “Words are arbitrary signs, having meaning only to the
 extent writers and readers share an understanding. . . .
 Language in general, and legislation in particular, is a
 social enterprise to which both speakers and listeners
 contribute, drawing on background understandings
 and the structure and circumstances of the utterance.”
 Herrmann v. Cencom Cable Assocs., Inc., 978 F. 2d 978,
 982 (CA7 1992).
 Consequently, “[s]licing a statute into phrases while ig-
noring . . . the setting of the enactment . . . is a formula for
disaster.” Ibid.; see also Continental Can Co. v. Chicago
Truck Drivers, Helpers and Warehouse Workers Union (In-
dependent) Pension Fund, 916 F. 2d 1154, 1157 (CA7 1990)
(“You don’t have to be Ludwig Wittgenstein or Hans-Georg
Gadamer to know that successful communication depends
on meanings shared by interpretive communities”).
 Thus, when textualism is properly understood, it calls for
an examination of the social context in which a statute was
enacted because this may have an important bearing on
what its words were understood to mean at the time of en-
actment. Textualists do not read statutes as if they were
messages picked up by a powerful radio telescope from a

distant and utterly unknown civilization. Statutes consist
of communications between members of a particular lin-
guistic community, one that existed in a particular place
and at a particular time, and these communications must
therefore be interpreted as they were understood by that
community at that time.
 For this reason, it is imperative to consider how Ameri-
cans in 1964 would have understood Title VII’s prohibition
of discrimination because of sex. To get a picture of this, we
may imagine this scene. Suppose that, while Title VII was
under consideration in Congress, a group of average Amer-
icans decided to read the text of the bill with the aim of
writing or calling their representatives in Congress and
conveying their approval or disapproval. What would these
ordinary citizens have taken “discrimination because of
sex” to mean? Would they have thought that this language
prohibited discrimination because of sexual orientation or
gender identity?
 B
 The answer could not be clearer. In 1964, ordinary Amer-
icans reading the text of Title VII would not have dreamed
that discrimination because of sex meant discrimination be-
cause of sexual orientation, much less gender identity. The
ordinary meaning of discrimination because of “sex” was
discrimination because of a person’s biological sex, not sex-
ual orientation or gender identity. The possibility that dis-
crimination on either of these grounds might fit within
some exotic understanding of sex discrimination would not
have crossed their minds.
 1
 In 1964, the concept of prohibiting discrimination “be-
cause of sex” was no novelty. It was a familiar and well-
understood concept, and what it meant was equal treat-
ment for men and women.

 ALITO, J., dissenting

 Long before Title VII was adopted, many pioneering state
and federal laws had used language substantively indistin-
guishable from Title VII’s critical phrase, “discrimination
because of sex.” For example, the California Constitution
of 1879 stipulated that no one, “on account of sex, [could] be
disqualified from entering upon or pursuing any lawful
business, vocation, or profession.” Art. XX, §18 (emphasis
added). It also prohibited a student’s exclusion from any
state university department “on account of sex.” Art. IX,
§9; accord, Mont. Const., Art. XI, §9 (1889).
 Wyoming’s first Constitution proclaimed broadly that
“[b]oth male and female citizens of this state shall equally
enjoy all civil, political and religious rights and privileges,”
Art. VI, §1 (1890), and then provided specifically that “[i]n
none of the public schools . . . shall distinction or discrimi-
nation be made on account of sex,” Art. VII, §10 (emphasis
added); see also §16 (the “university shall be equally open
to students of both sexes”). Washington’s Constitution like-
wise required “ample provision for the education of all chil-
dren . . . without distinction or preference on account of . . .
sex.” Art. IX, §1 (1889) (emphasis added).
 The Constitution of Utah, adopted in 1895, provided that
the right to vote and hold public office “shall not be denied
or abridged on account of sex.” Art. IV, §1 (emphasis added).
And in the next sentence it made clear what “on account of
sex” meant, stating that “[b]oth male and female citizens
. . . shall enjoy equally all civil, political and religious rights
and privileges.” Ibid.
 The most prominent example of a provision using this
language was the Nineteenth Amendment, ratified in 1920,
which bans the denial or abridgment of the right to vote “on
account of sex.” U. S. Const., Amdt. 19. Similar language
appeared in the proposal of the National Woman’s Party for
an Equal Rights Amendment. As framed in 1921, this pro-
posal forbade all “political, civil or legal disabilities or ine-
qualities on account of sex, [o]r on account of marriage.”

 In 1952, the new Constitution for Puerto Rico, which was

in naturalization “because of . . . sex.” 8 U. S. C. §1422 (em-

added).
 In short, the concept of discrimination “because of,” “on
account of,” or “on the basis of ” sex was well understood. It
was part of the campaign for equality that had been waged
by women’s rights advocates for more than a century, and
what it meant was equal treatment for men and women.22
 2
 Discrimination “because of sex” was not understood as
having anything to do with discrimination because of sex-
ual orientation or transgender status. Any such notion
would have clashed in spectacular fashion with the societal
norms of the day.
 For most 21st-century Americans, it is painful to be re-
minded of the way our society once treated gays and lesbi-
ans, but any honest effort to understand what the terms of
Title VII were understood to mean when enacted must take
into account the societal norms of that time. And the plain
truth is that in 1964 homosexuality was thought to be a
mental disorder, and homosexual conduct was regarded as
morally culpable and worthy of punishment.


——————
 22 Analysis of the way Title VII’s key language was used in books and

articles during the relevant time period supports this conclusion. A
study searched a vast database of documents from that time to determine
how the phrase “discriminate against . . . because of [some trait]” was
used. Phillips, The Overlooked Evidence in the Title VII Cases: The Lin-
guistic (and Therefore Textualist) Principle of Compositionality (manu-
script, at 3) (May 11, 2020) (brackets in original), https://ssrn.com/
abstract=3585940. The study found that the phrase was used to denote
discrimination against “someone . . . motivated by prejudice, or biased
ideas or attitudes . . . directed at people with that trait in particular.”
Id., at 7 (emphasis deleted). In other words, “discriminate against” was
“associated with negative treatment directed at members of a discrete
group.” Id., at 5. Thus, as used in 1964, “discrimination because of sex”
would have been understood to mean discrimination against a woman or
a man based on “unfair beliefs or attitudes” about members of that par-
ticular sex. Id., at 7.

 In its then-most recent Diagnostic and Statistical Manual
of Mental Disorders (1952) (DSM–I), the American Psychi-
atric Association (APA) classified same-sex attraction as a
“sexual deviation,” a particular type of “sociopathic person-
ality disturbance,” id., at 38–39, and the next edition, is-
sued in 1968, similarly classified homosexuality as a “sex-
ual deviatio[n],” Diagnostic and Statistical Manual of
Mental Disorders 44 (2d ed.) (DSM–II). It was not until the
sixth printing of the DSM–II in 1973 that this was
changed.23
 Society’s treatment of homosexuality and homosexual
conduct was consistent with this understanding. Sodomy
was a crime in every State but Illinois, see W. Eskridge,
Dishonorable Passions 387–407 (2008), and in the District
of Columbia, a law enacted by Congress made sodomy a fel-
ony punishable by imprisonment for up to 10 years and per-
mitted the indefinite civil commitment of “sexual psycho-
path[s],” Act of June 9, 1948, §§104, 201–207, 62 Stat. 347–

 This view of homosexuality was reflected in the rules gov-
erning the federal work force. In 1964, federal “[a]gencies
could deny homosexual men and women employment be-
cause of their sexual orientation,” and this practice contin-
ued until 1975. GAO, D. Heivilin, Security Clearances:
Consideration of Sexual Orientation in the Clearance Pro-
cess 2 (GAO/NSIAD–95–21, 1995). See, e.g., Anonymous v.
Macy, 398 F. 2d 317, 318 (CA5 1968) (affirming dismissal of
postal employee for homosexual acts).
 In 1964, individuals who were known to be homosexual
could not obtain security clearances, and any who possessed
clearances were likely to lose them if their orientation was
discovered. A 1953 Executive Order provided that back-
ground investigations should look for evidence of “sexual
perversion,” as well as “[a]ny criminal, infamous, dishonest,
immoral, or notoriously disgraceful conduct.” Exec. Order
No. 10450, §8(a)(1)(iii), 3 CFR 938 (1949–1953 Comp.).
“Until about 1991, when agencies began to change their se-
curity policies and practices regarding sexual orientation,
there were a number of documented cases where defense
civilian or contractor employees’ security clearances were
denied or revoked because of their sexual orientation.”
GAO, Security Clearances, at 2. See, e.g., Adams v. Laird,
 420 F. 2d 230, 240 (CADC 1969) (upholding denial of secu-
rity clearance to defense contractor employee because he
had “engaged in repeated homosexual acts”); see also Web-
ster v. Doe, 486 U. S. 592, 595, 601 (1988) (concluding that
decision to fire a particular individual because he was ho-
mosexual fell within the “discretion” of the Director of Cen-
tral Intelligence under the National Security Act of 1947
and thus was unreviewable under the APA).
 The picture in state employment was similar. In 1964, it
was common for States to bar homosexuals from serving as
teachers. An article summarizing the situation 15 years af-
ter Title VII became law reported that “[a]ll states have
statutes that permit the revocation of teaching certificates

(or credentials) for immorality, moral turpitude, or unpro-
fessionalism,” and, the survey added, “[h]omosexuality is
considered to fall within all three categories.”25
 The situation in California is illustrative. California laws
prohibited individuals who engaged in “immoral conduct”
(which was construed to include homosexual behavior), as
well as those convicted of “sex offenses” (like sodomy), from
employment as teachers. Cal. Educ. Code Ann. §§13202,
13207, 13209, 13218, 13255 (West 1960). The teaching cer-
tificates of individuals convicted of engaging in homosexual
acts were revoked. See, e.g., Sarac v. State Bd. of Ed., 249
Cal. App. 2d 58 , 62–64, 57 Cal. Rptr. 69 , 72–73 (1967) (up-
holding revocation of secondary teaching credential from
teacher who was convicted of engaging in homosexual con-
duct on public beach), overruled in part, Morrison v. State
Bd. of Ed., 1 Cal. 3d 214 , 461 P. 2d 375 (1969).
 In Florida, the legislature enacted laws authorizing the
revocation of teaching certificates for “misconduct involving
moral turpitude,” Fla. Stat. Ann. §229.08 (16) (1961), and
this law was used to target homosexual conduct. In 1964,
a legislative committee was wrapping up a 6-year campaign
to remove homosexual teachers from public schools and
state universities. As a result of these efforts, the state
board of education apparently revoked at least 71 teachers’
certificates and removed at least 14 university professors.
Eskridge, Dishonorable Passions, at 103.
 Individuals who engaged in homosexual acts also faced
the loss of other occupational licenses, such as those needed
to work as a “lawyer, doctor, mortician, [or] beautician.”26

public bathroom).
 In 1964 and for many years thereafter, homosexuals were
barred from the military. See, e.g., Army Reg. 635–89, §I(2)
(a) (July 15, 1966) (“Personnel who voluntarily engage in
homosexual acts, irrespective of sex, will not be permitted
to serve in the Army in any capacity, and their prompt sep-
aration is mandatory”); Army Reg. 600–443, §I(2) (April 10,
1953) (similar). Prohibitions against homosexual conduct
by members of the military were not eliminated until 2010.
See Don’t Ask, Don’t Tell Repeal Act of 2010, 124 Stat. 3515 
(repealing 10 U. S. C. §654 , which required members of the
Armed Forces to be separated for engaging in homosexual
conduct).
 Homosexuals were also excluded from entry into the
United States. The Immigration and Nationality Act of
1952 (INA) excluded aliens “afflicted with psychopathic per-
sonality.” 8 U. S. C. §1182 (a)(4) (1964 ed.). In Boutilier v.
INS, 387 U. S. 118 , 120–123 (1967), this Court, relying on
the INA’s legislative history, interpreted that term to en-
compass homosexuals and upheld an alien’s deportation on
that ground. Three Justices disagreed with the majority’s
interpretation of the phrase “psychopathic personality.”27
But it apparently did not occur to anyone to argue that the
Court’s interpretation was inconsistent with the INA’s ex-
press prohibition of discrimination “because of sex.” That
was how our society—and this Court—saw things a half
century ago. Discrimination because of sex and discrimina-
tion because of sexual orientation were viewed as two en-
tirely different concepts.
 To its credit, our society has now come to recognize the
injustice of past practices, and this recognition provides the
impetus to “update” Title VII. But that is not our job. Our

duty is to understand what the terms of Title VII were un-
derstood to mean when enacted, and in doing so, we must
take into account the societal norms of that time. We must
therefore ask whether ordinary Americans in 1964 would
have thought that discrimination because of “sex” carried
some exotic meaning under which private-sector employers
would be prohibited from engaging in a practice that repre-
sented the official policy of the Federal Government with
respect to its own employees. We must ask whether Amer-
icans at that time would have thought that Title VII banned
discrimination against an employee for engaging in conduct
that Congress had made a felony and a ground for civil
commitment.
 The questions answer themselves. Even if discrimination
based on sexual orientation or gender identity could be
squeezed into some arcane understanding of sex discrimi-
nation, the context in which Title VII was enacted would
tell us that this is not what the statute’s terms were under-
stood to mean at that time. To paraphrase something Jus-
tice Scalia once wrote, “our job is not to scavenge the world
of English usage to discover whether there is any possible
meaning” of discrimination because of sex that might be
broad enough to encompass discrimination because of sex-
ual orientation or gender identity. Chisom v. Roemer, 501
U. S. 380, 410 (1991) (dissenting opinion). Without strong
evidence to the contrary (and there is none here), our job is
to ascertain and apply the “ordinary meaning” of the stat-
ute. Ibid. And in 1964, ordinary Americans most certainly
would not have understood Title VII to ban discrimination
because of sexual orientation or gender identity.
 The Court makes a tiny effort to suggest that at least
some people in 1964 might have seen what Title VII really
means. Ante, at 26. What evidence does it adduce? One
complaint filed in 1969, another filed in 1974, and argu-
ments made in the mid-1970s about the meaning of the
Equal Rights Amendment. Ibid. To call this evidence

merely feeble would be generous.
 C
 While Americans in 1964 would have been shocked to
learn that Congress had enacted a law prohibiting sexual
orientation discrimination, they would have been bewil-
dered to hear that this law also forbids discrimination on
the basis of “transgender status” or “gender identity,” terms
that would have left people at the time scratching their
heads. The term “transgender” is said to have been coined
“ ‘in the early 1970s,’ ”28 and the term “gender identity,” now
understood to mean “[a]n internal sense of being male, fe-
male or something else,”29 apparently first appeared in an
academic article in 1964.30 Certainly, neither term was in
common parlance; indeed, dictionaries of the time still pri-
marily defined the word “gender” by reference to grammat-
ical classifications. See, e.g., American Heritage Diction-
ary, at 548 (def. 1(a)) (“Any set of two or more categories,
such as masculine, feminine, and neuter, into which words

ence between an individual’s gender identity and the
gender assigned at birth,”31 the current understanding of
the concept postdates the enactment of Title VII. Nothing
resembling what is now called gender dysphoria appeared
in either DSM–I (1952) or DSM–II (1968). It was not until
1980 that the APA, in DSM–III, recognized two main psy-
chiatric diagnoses related to this condition, “Gender Iden-
tity Disorder of Childhood” and “Transsexualism” in adoles-
cents and adults.32 DSM–III, at 261–266.
 The first widely publicized sex reassignment surgeries in
the United States were not performed until 1966,33 and the
great majority of physicians surveyed in 1969 thought that
an individual who sought sex reassignment surgery was ei-
ther “ ‘severely neurotic’ ” or “ ‘psychotic.’ ”34
 It defies belief to suggest that the public meaning of dis-
crimination because of sex in 1964 encompassed discrimi-
nation on the basis of a concept that was essentially un-
known to the public at that time.

clear, and therefore it simply does not matter whether peo-
ple in 1964 were “smart enough to realize” what its lan-
guage means. Hively, 853 F. 3d, at 357 (Posner, J., concur-
ring). According to the Court, an argument that looks to
the societal norms of those times represents an impermis-
sible attempt to displace the statutory language. Ante, at
25–26.
 The Court’s argument rests on a false premise. As al-
ready explained at length, the text of Title VII does not pro-
hibit discrimination because of sexual orientation or gender
identity. And what the public thought about those issues
in 1964 is relevant and important, not because it provides
a ground for departing from the statutory text, but because
it helps to explain what the text was understood to mean
when adopted.
 In arguing that we must put out of our minds what we
know about the time when Title VII was enacted, the Court
relies on Justice Scalia’s opinion for the Court in Oncale v.
Sundowner Offshore Services, Inc., 523 U. S. 75 (1998). But
Oncale is nothing like these cases, and no one should be
taken in by the majority’s effort to enlist Justice Scalia in
its updating project.
 The Court’s unanimous decision in Oncale was thor-
oughly unremarkable. The Court held that a male em-
ployee who alleged that he had been sexually harassed at
work by other men stated a claim under Title VII. Although
the impetus for Title VII’s prohibition of sex discrimination
was to protect women, anybody reading its terms would im-
mediately appreciate that it applies equally to both sexes,
and by the time Oncale reached the Court, our precedent
already established that sexual harassment may constitute
sex discrimination within the meaning of Title VII. See
Meritor Savings Bank, FSB v. Vinson, 477 U. S. 57 (1986).
Given these premises, syllogistic reasoning dictated the
holding.

 ALITO, J., dissenting

 What today’s decision latches onto are Oncale’s com-
ments about whether “ ‘male-on-male sexual harassment’ ”
was on Congress’s mind when it enacted Title VII. Ante, at
28 (quoting 523 U. S., at 79 ). The Court in Oncale observed
that this specific type of behavior “was assuredly not the
principal evil Congress was concerned with when it enacted
Title VII,” but it found that immaterial because “statutory
prohibitions often go beyond the principal evil to cover rea-
sonably comparable evils, and it is ultimately the provisions
of our laws rather than the principal concerns of our legis-
lators by which we are governed.” 523 U. S., at 79 (empha-
sis added).
 It takes considerable audacity to read these comments as
committing the Court to a position on deep philosophical
questions about the meaning of language and their implica-
tions for the interpretation of legal rules. These comments
are better understood as stating mundane and uncontrover-
sial truths. Who would argue that a statute applies only to
the “principal evils” and not lesser evils that fall within the
plain scope of its terms? Would even the most ardent “pur-
posivists” and fans of legislative history contend that
congressional intent is restricted to Congress’s “principal
concerns”?
 Properly understood, Oncale does not provide the slight-
est support for what the Court has done today. For one
thing, it would be a wild understatement to say that dis-
crimination because of sexual orientation and transgender
status was not the “principal evil” on Congress’s mind in
1964. Whether we like to admit it now or not, in the think-
ing of Congress and the public at that time, such discrimi-
nation would not have been evil at all.
 But the more important difference between these cases
and Oncale is that here the interpretation that the Court
adopts does not fall within the ordinary meaning of the stat-
utory text as it would have been understood in 1964. To
38 BOSTOCK v. CLAYTON COUNTY

 ALITO, J., dissenting

decide for the defendants in Oncale, it would have been nec-
essary to carve out an exception to the statutory text. Here,
no such surgery is at issue. Even if we totally disregard the
societal norms of 1964, the text of Title VII does not support
the Court’s holding. And the reasoning of Oncale does not
preclude or counsel against our taking those norms into ac-
count. They are relevant, not for the purpose of creating an
exception to the terms of the statute, but for the purpose of
better appreciating how those terms would have been un-
derstood at the time.

 The Court argues that two other decisions––Phillips v.
Martin Marietta Corp., 400 U. S. 542 (1971) (per curiam),
and Los Angeles Dept. of Water and Power v. Manhart, 435
U. S. 702 (1978)––buttress its decision, but those cases
merely held that Title VII prohibits employer conduct that
plainly constitutes discrimination because of biological sex.
In Philips, the employer treated women with young chil-
dren less favorably than men with young children. In Man-
hart, the employer required women to make larger pension
contributions than men. It is hard to see how these hold-
ings assist the Court.
 The Court extracts three “lessons” from Phillips, Man-
hart, and Oncale, but none sheds any light on the question
before us. The first lesson is that “it’s irrelevant what an
employer might call its discriminatory practice, how others
might label it, or what else might motivate it.” Ante, at 14.
This lesson is obviously true but proves nothing. As to the
label attached to a practice, has anyone ever thought that
the application of a law to a person’s conduct depends on
how it is labeled? Could a bank robber escape conviction by
saying he was engaged in asset enhancement? So if an em-
ployer discriminates because of sex, the employer is liable
no matter what it calls its conduct, but if the employer’s
 Cite as: 590 U. S. ____ (2020) 39

 ALITO, J., dissenting

conduct is not sex discrimination, the statute does not ap-
ply. Thus, this lesson simply takes us back to the question
whether discrimination because of sexual orientation or
gender identity is a form of discrimination because of bio-
logical sex. For reasons already discussed, see Part I–A,
supra, it is not.
 It likewise proves nothing of relevance here to note that
an employer cannot escape liability by showing that dis-
crimination on a prohibited ground was not its sole motiva-
tion. So long as a prohibited ground was a motivating fac-
tor, the existence of other motivating factors does not defeat
liability.
 The Court makes much of the argument that “[i]n Phil-
lips, the employer could have accurately spoken of its policy
as one based on ‘motherhood.’ ” Ante, at 14; see also ante,
at 16. But motherhood, by definition, is a condition that can
be experienced only by women, so a policy that distin-
guishes between motherhood and parenthood is necessarily
a policy that draws a sex-based distinction. There was sex
discrimination in Phillips, because women with children
were treated disadvantageously compared to men with
children.
 Lesson number two—“the plaintiff ’s sex need not be the
sole or primary cause of the employer’s adverse action,”
ante, at 14—is similarly unhelpful. The standard of causa-
tion in these cases is whether sex is necessarily a “motivat-
ing factor” when an employer discriminates on the basis of
sexual orientation or gender identity. 42 U. S. C. §2000e–
2(m). But the essential question—whether discrimination
because of sexual orientation or gender identity constitutes
sex discrimination—would be the same no matter what cau-
sation standard applied. The Court’s extensive discussion
of causation standards is so much smoke.
 Lesson number three––“an employer cannot escape lia-
bility by demonstrating that it treats males and females
comparably as groups,” ante, at 15, is also irrelevant. There
40 BOSTOCK v. CLAYTON COUNTY

 ALITO, J., dissenting

is no dispute that discrimination against an individual em-
ployee based on that person’s sex cannot be justified on the
ground that the employer’s treatment of the average em-
ployee of that sex is at least as favorable as its treatment of
the average employee of the opposite sex. Nor does it mat-
ter if an employer discriminates against only a subset of
men or women, where the same subset of the opposite sex
is treated differently, as in Phillips. That is not the issue
here. An employer who discriminates equally on the basis
of sexual orientation or gender identity applies the same
criterion to every affected individual regardless of sex. See
Part I–A, supra.

 Because the opinion of the Court flies a textualist flag, I
have taken pains to show that it cannot be defended on tex-
tualist grounds. But even if the Court’s textualist argu-
ment were stronger, that would not explain today’s deci-
sion. Many Justices of this Court, both past and present,
have not espoused or practiced a method of statutory inter-
pretation that is limited to the analysis of statutory text.
Instead, when there is ambiguity in the terms of a statute,
they have found it appropriate to look to other evidence of
“congressional intent,” including legislative history.
 So, why in these cases are congressional intent and the
legislative history of Title VII totally ignored? Any assess-
ment of congressional intent or legislative history seriously
undermines the Court’s interpretation.

 As the Court explained in General Elec. Co. v. Gilbert, 429
U. S. 125, 143 (1976), the legislative history of Title VII’s
prohibition of sex discrimination is brief, but it is neverthe-
less revealing. The prohibition of sex discrimination was

House of Representatives,” Meritor Savings Bank, 477
U. S., at 63 , by Representative Howard Smith, the Chair-
man of the Rules Committee. See 110 Cong. Rec. 2577
(1964). Representative Smith had been an ardent opponent
of the civil rights bill, and it has been suggested that he
added the prohibition against discrimination on the basis of
“sex” as a poison pill. See, e.g., Ulane v. Eastern Airlines,
Inc., 742 F. 2d 1081, 1085 (CA7 1984). On this theory, Rep-
resentative Smith thought that prohibiting employment
discrimination against women would be unacceptable to
Members who might have otherwise voted in favor of the
bill and that the addition of this prohibition might bring
about the bill’s defeat.35 But if Representative Smith had
been looking for a poison pill, prohibiting discrimination on
the basis of sexual orientation or gender identity would
have been far more potent. However, neither Representa-
tive Smith nor any other Member said one word about the
possibility that the prohibition of sex discrimination might
have that meaning. Instead, all the debate concerned dis-
crimination on the basis of biological sex.36 See 110 Cong.
Rec. 2577–2584.

were, the meaning of the adoption of the prohibition of sex
discrimination is clear. It was no accident. It grew out of
“a long history of women’s rights advocacy that had increas-
ingly been gaining mainstream recognition and ac-
ceptance,” and it marked a landmark achievement in the
path toward fully equal rights for women. Id., at 140. “Dis-
crimination against gay women and men, by contrast, was
not on the table for public debate . . . [i]n those dark, pre-
Stonewall days.” Ibid.
 For those who regard congressional intent as the touch-
stone of statutory interpretation, the message of Title VII’s
legislative history cannot be missed.
 C
 Post-enactment events only clarify what was apparent
when Title VII was enacted. As noted, bills to add “sexual
orientation” to Title VII’s list of prohibited grounds were in-
troduced in every Congress beginning in 1975, see supra, at
2, and two such bills were before Congress in 199137 when
it made major changes in Title VII. At that time, the three
Courts of Appeals to reach the issue had held that Title VII
does not prohibit discrimination because of sexual orienta-
tion,38 two other Circuits had endorsed that interpretation
in dicta,39 and no Court of Appeals had held otherwise. Sim-
ilarly, the three Circuits to address the application of Title
VII to transgender persons had all rejected the argument

that it covered discrimination on this basis.40 These were
also the positions of the EEOC.41 In enacting substantial
changes to Title VII, the 1991 Congress abrogated numer-
ous judicial decisions with which it disagreed. If it also dis-
agreed with the decisions regarding sexual orientation and
transgender discrimination, it could have easily overruled
those as well, but it did not do so.42
 After 1991, six other Courts of Appeals reached the issue
of sexual orientation discrimination, and until 2017, every
single Court of Appeals decision understood Title VII’s pro-
hibition of “discrimination because of sex” to mean discrim-
ination because of biological sex. See, e.g., Higgins v. New
Balance Athletic Shoe, Inc., 194 F. 3d 252, 259 (CA1

 42 In more recent legislation, when Congress has wanted to reach acts

committed because of sexual orientation or gender identity, it has re-
ferred to those grounds by name. See, e.g., 18 U. S. C. §249 (a)(2)(A) (hate

2007).
 The Court observes that “[t]he people are entitled to rely
on the law as written, without fearing that courts might
disregard its plain terms,” ante, at 24, but it has no qualms
about disregarding over 50 years of uniform judicial inter-
pretation of Title VII’s plain text. Rather, the Court makes
the jaw-dropping statement that its decision exemplifies
“judicial humility.” Ante, at 31. Is it humble to maintain,
not only that Congress did not understand the terms it en-
acted in 1964, but that all the Circuit Judges on all the pre-
2017 cases could not see what the phrase discrimination
“because of sex” really means? If today’s decision is humble,
it is sobering to imagine what the Court might do if it de-
cided to be bold.
 IV
 What the Court has done today––interpreting discrimi-
nation because of “sex” to encompass discrimination be-
cause of sexual orientation or gender identity––is virtually
certain to have far-reaching consequences. Over 100 fed-
eral statutes prohibit discrimination because of sex. See
Appendix C, infra; e.g., 20 U. S. C. §1681 (a) (Title IX); 42
U. S. C. §3631 (Fair Housing Act); 15 U. S. C. 1691(a)(1)
(Equal Credit Opportunity Act). The briefs in these cases
have called to our attention the potential effects that the
Court’s reasoning may have under some of these laws, but
the Court waves those considerations aside. As to Title VII
itself, the Court dismisses questions about “bathrooms,
locker rooms, or anything else of the kind.” Ante, at 31. And
it declines to say anything about other statutes whose
terms mirror Title VII’s.
 The Court’s brusque refusal to consider the consequences
of its reasoning is irresponsible. If the Court had allowed
the legislative process to take its course, Congress would
have had the opportunity to consider competing interests
and might have found a way of accommodating at least
 Cite as: 590 U. S. ____ (2020) 45

 ALITO, J., dissenting

some of them. In addition, Congress might have crafted
special rules for some of the relevant statutes. But by in-
tervening and proclaiming categorically that employment
discrimination based on sexual orientation or gender iden-
tity is simply a form of discrimination because of sex, the
Court has greatly impeded—and perhaps effectively
ended—any chance of a bargained legislative resolution.
Before issuing today’s radical decision, the Court should
have given some thought to where its decision would lead.
 As the briefing in these cases has warned, the position
that the Court now adopts will threaten freedom of religion,
freedom of speech, and personal privacy and safety. No one
should think that the Court’s decision represents an unal-
loyed victory for individual liberty.
 I will briefly note some of the potential consequences of
the Court’s decision, but I do not claim to provide a compre-
hensive survey or to suggest how any of these issues should
necessarily play out under the Court’s reasoning.43
 “[B]athrooms, locker rooms, [and other things] of [that]
kind.” The Court may wish to avoid this subject, but it is a
matter of concern to many people who are reticent about
disrobing or using toilet facilities in the presence of individ-
uals whom they regard as members of the opposite sex. For
some, this may simply be a question of modesty, but for oth-
ers, there is more at stake. For women who have been vic-
timized by sexual assault or abuse, the experience of seeing
an unclothed person with the anatomy of a male in a con-
fined and sensitive location such as a bathroom or locker
room can cause serious psychological harm.44
 Under the Court’s decision, however, transgender per-
sons will be able to argue that they are entitled to use a
bathroom or locker room that is reserved for persons of the

sex with which they identify, and while the Court does not
define what it means by a transgender person, the term
may apply to individuals who are “gender fluid,” that is, in-
dividuals whose gender identity is mixed or changes over
time.45 Thus, a person who has not undertaken any physi-
cal transitioning may claim the right to use the bathroom
or locker room assigned to the sex with which the individual
identifies at that particular time. The Court provides no
clue why a transgender person’s claim to such bathroom or
locker room access might not succeed.
 A similar issue has arisen under Title IX, which prohibits
sex discrimination by any elementary or secondary school
and any college or university that receives federal financial
assistance.46 In 2016, a Department of Justice advisory
warned that barring a student from a bathroom assigned to
individuals of the gender with which the student identifies
constitutes unlawful sex discrimination,47 and some lower
court decisions have agreed. See Whitaker v. Kenosha Uni-
fied School Dist. No. 1 Bd. of Ed., 858 F. 3d 1034, 1049 (CA7

 Women’s sports. Another issue that may come up under
both Title VII and Title IX is the right of a transgender in-
dividual to participate on a sports team or in an athletic
competition previously reserved for members of one biolog-
ical sex.48 This issue has already arisen under Title IX,
where it threatens to undermine one of that law’s major
achievements, giving young women an equal opportunity to
participate in sports. The effect of the Court’s reasoning
may be to force young women to compete against students
who have a very significant biological advantage, including
students who have the size and strength of a male but iden-
tify as female and students who are taking male hormones
in order to transition from female to male. See, e.g., Com-
plaint in Soule v. Connecticut Assn. of Schools, No. 3:20–cv–

policy allowing transgender students to compete in girls’

 The logic of the Court’s decision could even affect profes-
sional sports. Under the Court’s holding that Title VII pro-
hibits employment discrimination because of transgender
status, an athlete who has the physique of a man but iden-
tifies as a woman could claim the right to play on a women’s
professional sports team. The owners of the team might try
to claim that biological sex is a bona fide occupational qual-
ification (BFOQ) under 42 U. S. C. §2000e–2(e), but the
BFOQ exception has been read very narrowly. See Dothard
v. Rawlinson, 433 U. S. 321, 334 (1977).
 Housing. The Court’s decision may lead to Title IX cases
against any college that resists assigning students of the

IX, 20 U. S. C. §1686 , allows schools to maintain “separate

based employment practices of numerous churches, syna-
gogues, mosques, and other religious institutions.”51 They
argue that “[r]eligious organizations need employees who
actually live the faith,”52 and that compelling a religious or-
ganization to employ individuals whose conduct flouts the
tenets of the organization’s faith forces the group to com-
municate an objectionable message.
 This problem is perhaps most acute when it comes to the
employment of teachers. A school’s standards for its faculty
“communicate a particular way of life to its students,” and
a “violation by the faculty of those precepts” may under-
mine the school’s “moral teaching.”53 Thus, if a religious
school teaches that sex outside marriage and sex reassign-
ment procedures are immoral, the message may be lost if
the school employs a teacher who is in a same-sex relation-
ship or has undergone or is undergoing sex reassignment.
Yet today’s decision may lead to Title VII claims by such
teachers and applicants for employment.
 At least some teachers and applicants for teaching posi-
tions may be blocked from recovering on such claims by the
“ministerial exception” recognized in Hosanna-Tabor Evan-
gelical Lutheran Church and School v. EEOC, 565 U. S. 171 
(2012). Two cases now pending before the Court present
the question whether teachers who provide religious in-
struction can be considered to be “ministers.”54 But even if
teachers with those responsibilities qualify, what about
other very visible school employees who may not qualify for

 Healthcare. Healthcare benefits may emerge as an in-

employees have brought suit under Title VII to challenge
employer-provided health insurance plans that do not cover
costly sex reassignment surgery.56 Similar claims have
been brought under the Affordable Care Act (ACA), which
broadly prohibits sex discrimination in the provision of
healthcare.57

 Such claims present difficult religious liberty issues be-
cause some employers and healthcare providers have
strong religious objections to sex reassignment procedures,
and therefore requiring them to pay for or to perform these
procedures will have a severe impact on their ability to
honor their deeply held religious beliefs.
 Freedom of speech. The Court’s decision may even affect
the way employers address their employees and the way
teachers and school officials address students. Under es-
tablished English usage, two sets of sex-specific singular
personal pronouns are used to refer to someone in the third
person (he, him, and his for males; she, her, and hers for
females). But several different sets of gender-neutral pro-
nouns have now been created and are preferred by some in-
dividuals who do not identify as falling into either of the
two traditional categories.58 Some jurisdictions, such as

 Section 1557 of the ACA, 42 U. S. C. §18116 , provides:
 “Except as otherwise provided for in this title (or an amendment made

 Constitutional claims. Finally, despite the important dif-
ferences between the Fourteenth Amendment and Title
VII, the Court’s decision may exert a gravitational pull in
constitutional cases. Under our precedents, the Equal Pro-
tection Clause prohibits sex-based discrimination unless a
“heightened” standard of review is met. Sessions v. Mo-
rales-Santana, 582 U. S. ___ , ___ (2017) (slip op., at 8);
United States v. Virginia, 518 U. S. 515 , 532–534 (1996).
By equating discrimination because of sexual orientation or
gender identity with discrimination because of sex, the
Court’s decision will be cited as a ground for subjecting all
three forms of discrimination to the same exacting standard
of review.
 Under this logic, today’s decision may have effects that
extend well beyond the domain of federal anti-
discrimination statutes. This potential is illustrated by
pending and recent lower court cases in which transgender
individuals have challenged a variety of federal, state, and
local laws and policies on constitutional grounds. See, e.g.,
Complaint in Hecox, No. 1: 20–CV–00184 (state law prohib-
iting transgender students from competing in school sports
in accordance with their gender identity); Second Amended

non-conformity).
 Although the Court does not want to think about the
consequences of its decision, we will not be able to avoid
those issues for long. The entire Federal Judiciary will be
mired for years in disputes about the reach of the Court’s
reasoning.
 * * *
 The updating desire to which the Court succumbs no
doubt arises from humane and generous impulses. Today,
many Americans know individuals who are gay, lesbian, or
transgender and want them to be treated with the dignity,
consideration, and fairness that everyone deserves. But the
authority of this Court is limited to saying what the law is.
 The Court itself recognizes this:
 “The place to make new legislation . . . lies in Congress.
 When it comes to statutory interpretation, our role is
 limited to applying the law’s demands as faithfully as
 we can in the cases that come before us.” Ante, at 31.
 It is easy to utter such words. If only the Court would
live by them.

Webster’s New International Dictionary 2296 (2d ed.
1953):

sex (sĕks), n. [F. sexe, fr. L. sexus; prob. orig., division, and
 akin to L. secare to cut. See SECTION.] 1. One of the two
 divisions of organisms formed on the distinction of male
 and female; males or females collectively. 2. The sum of
 the peculiarities of structure and function that distin-
 guish a male from a female organism; the character of be-
 ing male or female, or of pertaining to the distinctive
 function of the male or female in reproduction. Conjuga-
 tion, or fertilization (union of germplasm of two individu-
 als), a process evidently of great but not readily explain-
 able importance in the perpetuation of most organisms,
 seems to be the function of differentiation of sex, which
 occurs in nearly all organisms at least at some stage in
 their life history. Sex is manifested in the conjugating
 cells by the larger size, abundant food material, and im-
 mobility of the female gamete (egg, egg cell, or ovum), and
 the small size and the locomotive power of the male gam-
 ete (spermatozoon or spermatozoid), and in the adult or-
 ganisms often by many structural, physiological, and (in
 higher forms) psychological characters, aside from the
 necessary modification of the reproductive apparatus. Cf.
 HERMAPHRODITE, 1. In botany the term sex is often extended
 to the distinguishing peculiarities of staminate and pis-
 tillate flowers, and hence in dioecious plants to the indi-
 viduals bearing them.
 In many animals and plants the body and germ cells
 have been shown to contain one or more chromosomes of
 a special kind (called sex chromosomes; idiochromosomes;
 accessory chromosomes) in addition to the ordinary
 paired autosomes. These special chromosomes serve to
56 BOSTOCK v. CLAYTON COUNTY

 determine sex. In the simplest case, the male germ cells
 are of two types, one with and one without a single extra
 chromosome (X chromosome, or monosome). The egg cells
 in this case all possess an X chromosome, and on fertili-
 zation by the two types of sperm, male and female zygotes
 result, of respective constitution X, and XX. In many
 other animals and plants (probably including man) the
 male organism produces two types of gametes, one pos-
 sessing an X chromosome, the other a Y chromosome,
 these being visibly different members of a pair of chromo-
 somes present in the diploid state. In this case also, the
 female organism is XX, the eggs X, and the zygotes re-
 spectively male (XY) and female (XX). In another type of
 sex determination, as in certain moths and possibly in the
 fowl, the female produces two kinds of eggs, the male only
 one kind of sperm. Each type of egg contains one member
 of a pair of differentiated chromosomes, called respec-
 tively Z chromosomes and W chromosomes, while all the
 sperm cells contain a Z chromosome. In fertilization, un-
 ion of a Z with a W gives rise to a female, while union of
 two Z chromosomes produces a male. Cf. SECONDARY SEX

 ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
 APPEALS FOR THE SIXTH CIRCUIT
 [June 15, 2020]

 JUSTICE KAVANAUGH, dissenting.
 Like many cases in this Court, this case boils down to one
fundamental question: Who decides? Title VII of the Civil
Rights Act of 1964 prohibits employment discrimination
“because of ” an individual’s “race, color, religion, sex, or na-
tional origin.” The question here is whether Title VII
2 BOSTOCK v. CLAYTON COUNTY

 KAVANAUGH, J., dissenting

should be expanded to prohibit employment discrimination
because of sexual orientation. Under the Constitution’s
separation of powers, the responsibility to amend Title VII
belongs to Congress and the President in the legislative pro-
cess, not to this Court.
 The political branches are well aware of this issue. In
2007, the U. S. House of Representatives voted 235 to 184
to prohibit employment discrimination on the basis of sex-
ual orientation. In 2013, the U. S. Senate voted 64 to 32 in
favor of a similar ban. In 2019, the House again voted 236
to 173 to outlaw employment discrimination on the basis of
sexual orientation. Although both the House and Senate
have voted at different times to prohibit sexual orientation
discrimination, the two Houses have not yet come together
with the President to enact a bill into law.
 The policy arguments for amending Title VII are very
weighty. The Court has previously stated, and I fully agree,
that gay and lesbian Americans “cannot be treated as social
outcasts or as inferior in dignity and worth.” Masterpiece
Cakeshop, Ltd. v. Colorado Civil Rights Comm’n, 584 U. S.
___ , ___ (2018) (slip op., at 9).
 But we are judges, not Members of Congress. And in Al-
exander Hamilton’s words, federal judges exercise “neither
Force nor Will, but merely judgment.” The Federalist No.
78, p. 523 (J. Cooke ed. 1961). Under the Constitution’s
separation of powers, our role as judges is to interpret and
follow the law as written, regardless of whether we like the
result. Cf. Texas v. Johnson, 491 U. S. 397 , 420–421 (1989)
(Kennedy, J., concurring). Our role is not to make or amend
the law. As written, Title VII does not prohibit employment
discrimination because of sexual orientation.1

the basis of gender identity, this opinion’s legal analysis of discrimina-
tion on the basis of sexual orientation would apply in much the same way
to discrimination on the basis of gender identity.

 KAVANAUGH, J., dissenting

 I
 Title VII makes it unlawful for employers to discriminate
because of “race, color, religion, sex, or national origin.” 42
U. S. C. §2000e–2(a)(1).2 As enacted in 1964, Title VII did
not prohibit other forms of employment discrimination,
such as age discrimination, disability discrimination, or
sexual orientation discrimination.
 Over time, Congress has enacted new employment dis-
crimination laws. In 1967, Congress passed and President
Johnson signed the Age Discrimination in Employment Act.
 81 Stat. 602 . In 1973, Congress passed and President
Nixon signed the Rehabilitation Act, which in substance
prohibited disability discrimination against federal and cer-
tain other employees. 87 Stat. 355 . In 1990, Congress
passed and President George H. W. Bush signed the com-
prehensive Americans with Disabilities Act. 104 Stat. 327 .
 To prohibit age discrimination and disability discrimina-
tion, this Court did not unilaterally rewrite or update the


——————
 2 In full, the statute provides:

 “It shall be an unlawful employment practice for an employer—
 “(1) to fail or refuse to hire or to discharge any individual, or otherwise
to discriminate against any individual with respect to his compensation,
terms, conditions, or privileges of employment, because of such individ-
ual’s race, color, religion, sex, or national origin; or
 “(2) to limit, segregate, or classify his employees or applicants for em-
ployment in any way which would deprive or tend to deprive any indi-
vidual of employment opportunities or otherwise adversely affect his sta-
tus as an employee, because of such individual’s race, color, religion, sex,
or national origin.” 42 U. S. C. §2000e–2(a) (emphasis added).
 As the Court today recognizes, Title VII contains an important exemp-
tion for religious organizations. §2000e–1(a); see also §2000e–2(e). The
First Amendment also safeguards the employment decisions of religious
employers. See Hosanna-Tabor Evangelical Lutheran Church and
School v. EEOC, 565 U. S. 171 , 188–195 (2012). So too, the Religious
Freedom Restoration Act of 1993 exempts employers from federal laws
that substantially burden the exercise of religion, subject to limited ex-
ceptions. §2000bb–1.
4 BOSTOCK v. CLAYTON COUNTY

 KAVANAUGH, J., dissenting

law. Rather, Congress and the President enacted new leg-
islation, as prescribed by the Constitution’s separation of
powers.
 For several decades, Congress has considered numerous
bills to prohibit employment discrimination based on sexual
orientation. But as noted above, although Congress has
come close, it has not yet shouldered a bill over the legisla-
tive finish line.
 In the face of the unsuccessful legislative efforts (so far)
to prohibit sexual orientation discrimination, judges may
not rewrite the law simply because of their own policy
views. Judges may not update the law merely because they
think that Congress does not have the votes or the fortitude.
Judges may not predictively amend the law just because
they believe that Congress is likely to do it soon anyway.
 If judges could rewrite laws based on their own policy
views, or based on their own assessments of likely future
legislative action, the critical distinction between legisla-
tive authority and judicial authority that undergirds the
Constitution’s separation of powers would collapse, thereby
threatening the impartial rule of law and individual liberty.
As James Madison stated: “Were the power of judging
joined with the legislative, the life and liberty of the subject
would be exposed to arbitrary controul, for the judge would
then be the legislator.” The Federalist No. 47, at 326 (citing
Montesquieu). If judges could, for example, rewrite or up-
date securities laws or healthcare laws or gun laws or envi-
ronmental laws simply based on their own policy views, the
Judiciary would become a democratically illegitimate su-
per-legislature—unelected, and hijacking the important
policy decisions reserved by the Constitution to the people’s
elected representatives.
 Because judges interpret the law as written, not as they
might wish it were written, the first 10 U. S. Courts of Ap-
peals to consider whether Title VII prohibits sexual orien-
tation discrimination all said no. Some 30 federal judges
 Cite as: 590 U. S. ____ (2020) 5

 KAVANAUGH, J., dissenting

considered the question. All 30 judges said no, based on the
text of the statute. 30 out of 30.
 But in the last few years, a new theory has emerged. To
end-run the bedrock separation-of-powers principle that
courts may not unilaterally rewrite statutes, the plaintiffs
here (and, recently, two Courts of Appeals) have advanced
a novel and creative argument. They contend that discrim-
ination “because of sexual orientation” and discrimination
“because of sex” are actually not separate categories of dis-
crimination after all. Instead, the theory goes, discrimina-
tion because of sexual orientation always qualifies as dis-
crimination because of sex: When a gay man is fired
because he is gay, he is fired because he is attracted to men,
even though a similarly situated woman would not be fired
just because she is attracted to men. According to this the-
ory, it follows that the man has been fired, at least as a lit-
eral matter, because of his sex.
 Under this literalist approach, sexual orientation dis-
crimination automatically qualifies as sex discrimination,
and Title VII’s prohibition against sex discrimination there-
fore also prohibits sexual orientation discrimination—and
actually has done so since 1964, unbeknownst to everyone.
Surprisingly, the Court today buys into this approach.
Ante, at 9–12.
 For the sake of argument, I will assume that firing some-
one because of their sexual orientation may, as a very literal
matter, entail making a distinction based on sex. But to
prevail in this case with their literalist approach, the plain-
tiffs must also establish one of two other points. The plain-
tiffs must establish that courts, when interpreting a stat-
ute, adhere to literal meaning rather than ordinary
meaning. Or alternatively, the plaintiffs must establish
that the ordinary meaning of “discriminate because of
sex”—not just the literal meaning—encompasses sexual
orientation discrimination. The plaintiffs fall short on both
counts.
6 BOSTOCK v. CLAYTON COUNTY

 KAVANAUGH, J., dissenting

 First, courts must follow ordinary meaning, not literal
meaning. And courts must adhere to the ordinary meaning
of phrases, not just the meaning of the words in a phrase.
 There is no serious debate about the foundational inter-
pretive principle that courts adhere to ordinary meaning,
not literal meaning, when interpreting statutes. As Justice
Scalia explained, “the good textualist is not a literalist.” A.
Scalia, A Matter of Interpretation 24 (1997). Or as Profes-
sor Eskridge stated: The “prime directive in statutory inter-
pretation is to apply the meaning that a reasonable reader
would derive from the text of the law,” so that “for hard
cases as well as easy ones, the ordinary meaning (or the
‘everyday meaning’ or the ‘commonsense’ reading) of the
relevant statutory text is the anchor for statutory interpre-
tation.” W. Eskridge, Interpreting Law 33, 34–35 (2016)
(footnote omitted). Or as Professor Manning put it, proper
statutory interpretation asks “how a reasonable person,
conversant with the relevant social and linguistic conven-
tions, would read the text in context. This approach recog-
nizes that the literal or dictionary definitions of words will
often fail to account for settled nuances or background con-
ventions that qualify the literal meaning of language and,
in particular, of legal language.” Manning, The Absurdity
Doctrine, 116 Harv. L. Rev. 2387 , 2392–2393 (2003). Or as
Professor Nelson wrote: No “mainstream judge is interested
solely in the literal definitions of a statute’s words.” Nelson,
What Is Textualism?, 91 Va. L. Rev. 347 , 376 (2005). The
ordinary meaning that counts is the ordinary public mean-
ing at the time of enactment—although in this case, that
temporal principle matters little because the ordinary
meaning of “discriminate because of sex” was the same in
1964 as it is now.
 Judges adhere to ordinary meaning for two main reasons:
rule of law and democratic accountability. A society gov-
erned by the rule of law must have laws that are known and
understandable to the citizenry. And judicial adherence to
 Cite as: 590 U. S. ____ (2020) 7

 KAVANAUGH, J., dissenting

ordinary meaning facilitates the democratic accountability
of America’s elected representatives for the laws they enact.
Citizens and legislators must be able to ascertain the law
by reading the words of the statute. Both the rule of law
and democratic accountability badly suffer when a court
adopts a hidden or obscure interpretation of the law, and
not its ordinary meaning.
 Consider a simple example of how ordinary meaning dif-
fers from literal meaning. A statutory ban on “vehicles in
the park” would literally encompass a baby stroller. But no
good judge would interpret the statute that way because the
word “vehicle,” in its ordinary meaning, does not encompass
baby strollers.
 The ordinary meaning principle is longstanding and well
settled. Time and again, this Court has rejected literalism
in favor of ordinary meaning. Take a few examples:
  The Court recognized that beans may be seeds “in the
 language of botany or natural history,” but concluded
 that beans are not seeds “in commerce” or “in common
 parlance.” Robertson v. Salomon, 130 U. S. 412, 414 
 (1889).
  The Court explained that tomatoes are literally “the
 fruit of a vine,” but “in the common language of the
 people,” tomatoes are vegetables. Nix v. Hedden, 149
 U. S. 304, 307 (1893).
  The Court stated that the statutory term “vehicle” does
 not cover an aircraft: “No doubt etymologically it is
 possible to use the word to signify a conveyance work-
 ing on land, water or air . . . . But in everyday speech
 ‘vehicle’ calls up the picture of a thing moving on land.”
 McBoyle v. United States, 283 U. S. 25, 26 (1931).
  The Court pointed out that “this Court’s interpretation
 of the three-judge-court statutes has frequently devi-
 ated from the path of literalism.” Gonzalez v. Auto-
 matic Employees Credit Union, 419 U. S. 90, 96 (1974).
8 BOSTOCK v. CLAYTON COUNTY

 KAVANAUGH, J., dissenting

  The Court refused a reading of “mineral deposits” that
 would include water, even if “water is a ‘mineral,’ in
 the broadest sense of that word,” because it would
 bring about a “major . . . alteration in established legal
 relationships based on nothing more than an overly lit-
 eral reading of a statute, without any regard for its
 context or history.” Andrus v. Charlestone Stone Prod-
 ucts Co., 436 U. S. 604, 610, 616 (1978).
  The Court declined to interpret “facilitating” a drug
 distribution crime in a way that would cover purchas-
 ing drugs, because the “literal sweep of ‘facilitate’ sits
 uncomfortably with common usage.” Abuelhawa v.
 United States, 556 U. S. 816, 820 (2009).
  The Court rebuffed a literal reading of “personnel
 rules” that would encompass any rules that personnel
 must follow (as opposed to human resources rules
 about personnel), and stated that no one “using ordi-
 nary language would describe” personnel rules “in this
 manner.” Milner v. Department of Navy, 562 U. S. 562 ,
 578 (2011).
  The Court explained that, when construing statutory
 phrases such as “arising from,” it avoids “uncritical lit-
 eralism leading to results that no sensible person could
 have intended.” Jennings v. Rodriguez, 583 U. S. ___ ,
 ___–___ (2018) (plurality opinion) (slip op., at 9–10) (in-
 ternal quotation marks omitted).
 Those cases exemplify a deeply rooted principle: When
there is a divide between the literal meaning and the ordi-
nary meaning, courts must follow the ordinary meaning.
 Next is a critical point of emphasis in this case. The dif-
ference between literal and ordinary meaning becomes es-
pecially important when—as in this case—judges consider
phrases in statutes. (Recall that the shorthand version of

Courts must heed the ordinary meaning of the phrase as a
whole, not just the meaning of the words in the phrase.
That is because a phrase may have a more precise or con-
fined meaning than the literal meaning of the individual
words in the phrase. Examples abound. An “American
flag” could literally encompass a flag made in America, but
in common parlance it denotes the Stars and Stripes. A
“three-pointer” could literally include a field goal in football,
but in common parlance, it is a shot from behind the arc in
basketball. A “cold war” could literally mean any winter-
time war, but in common parlance it signifies a conflict
short of open warfare. A “washing machine” could literally
refer to any machine used for washing any item, but in eve-
ryday speech it means a machine for washing clothes.
 This Court has often emphasized the importance of stick-
ing to the ordinary meaning of a phrase, rather than the
meaning of words in the phrase. In FCC v. AT&T Inc., 562
U. S. 397 (2011), for example, the Court explained:
 “AT&T’s argument treats the term ‘personal privacy’
 as simply the sum of its two words: the privacy of a per-
 son. . . . But two words together may assume a more
 particular meaning than those words in isolation. We
 understand a golden cup to be a cup made of or resem-
 bling gold. A golden boy, on the other hand, is one who
 is charming, lucky, and talented. A golden opportunity
 is one not to be missed. ‘Personal’ in the phrase ‘per-
 sonal privacy’ conveys more than just ‘of a person.’ It
 suggests a type of privacy evocative of human con-
 cerns—not the sort usually associated with an entity
 like, say, AT&T.” Id., at 406 .

opinion uses “discriminate because of sex” as shorthand for “discriminate
. . . because of . . . sex.” Also, the plaintiffs do not dispute that the ordi-
nary meaning of the statutory phrase “discriminate” because of sex is the
same as the statutory phrase “to fail or refuse to hire or to discharge any
individual” because of sex.

 KAVANAUGH, J., dissenting

Exactly right and exactly on point in this case.
 Justice Scalia explained the extraordinary importance of
hewing to the ordinary meaning of a phrase: “Adhering to
the fair meaning of the text (the textualist’s touchstone)
does not limit one to the hyperliteral meaning of each word
in the text. In the words of Learned Hand: ‘a sterile liter-
alism . . . loses sight of the forest for the trees.’ The full
body of a text contains implications that can alter the literal
meaning of individual words.” A. Scalia & B. Garner, Read-
ing Law 356 (2012) (footnote omitted). Put another way,
“the meaning of a sentence may be more than that of the
separate words, as a melody is more than the notes.”
Helvering v. Gregory, 69 F. 2d 809 , 810–811 (CA2 1934) (L.
Hand, J.). Judges must take care to follow ordinary mean-
ing “when two words combine to produce a meaning that is
not the mechanical composition of the two words sepa-
rately.” Eskridge, Interpreting Law, at 62. Dictionaries are
not “always useful for determining the ordinary meaning of
word clusters (like ‘driving a vehicle’) or phrases and
clauses or entire sentences.” Id., at 44. And we must rec-
ognize that a phrase can cover a “dramatically smaller cat-
egory than either component term.” Id., at 62.
 If the usual evidence indicates that a statutory phrase
bears an ordinary meaning different from the literal
strung-together definitions of the individual words in the
phrase, we may not ignore or gloss over that discrepancy.
“Legislation cannot sensibly be interpreted by stringing to-
gether dictionary synonyms of each word and proclaiming
that, if the right example of the meaning of each is selected,
the ‘plain meaning’ of the statute leads to a particular re-
sult. No theory of interpretation, including textualism it-
self, is premised on such an approach.” 883 F. 3d 100, 144,

 KAVANAUGH, J., dissenting

 In other words, this Court’s precedents and longstanding
principles of statutory interpretation teach a clear lesson:
Do not simply split statutory phrases into their component
words, look up each in a dictionary, and then mechanically
put them together again, as the majority opinion today mis-
takenly does. See ante, at 5–9. To reiterate Justice Scalia’s
caution, that approach misses the forest for the trees.
 A literalist approach to interpreting phrases disrespects
ordinary meaning and deprives the citizenry of fair notice
of what the law is. It destabilizes the rule of law and
thwarts democratic accountability. For phrases as well as
terms, the “linchpin of statutory interpretation is ordinary
meaning, for that is going to be most accessible to the citi-
zenry desirous of following the law and to the legislators
and their staffs drafting the legal terms of the plans
launched by statutes and to the administrators and judges
implementing the statutory plan.” Eskridge, Interpreting
Law, at 81; see Scalia, A Matter of Interpretation, at 17.
 Bottom line: Statutory Interpretation 101 instructs
courts to follow ordinary meaning, not literal meaning, and
to adhere to the ordinary meaning of phrases, not just the
meaning of the words in a phrase.
 Second, in light of the bedrock principle that we must ad-
here to the ordinary meaning of a phrase, the question in
this case boils down to the ordinary meaning of the phrase
“discriminate because of sex.” Does the ordinary meaning
of that phrase encompass discrimination because of sexual
orientation? The answer is plainly no.


——————
than literal meaning. That canon tells courts to avoid construing a stat-
ute in a way that would lead to absurd consequences. The absurdity
canon, properly understood, is “an implementation of (rather than . . . an
exception to) the ordinary meaning rule.” W. Eskridge, Interpreting Law
72 (2016). “What the rule of absurdity seeks to do is what all rules of
interpretation seek to do: make sense of the text.” A. Scalia & B. Garner,
Reading Law 235 (2012).
12 BOSTOCK v. CLAYTON COUNTY

 KAVANAUGH, J., dissenting

 On occasion, it can be difficult for judges to assess ordi-
nary meaning. Not here. Both common parlance and com-
mon legal usage treat sex discrimination and sexual orien-
tation discrimination as two distinct categories of
discrimination—back in 1964 and still today.
 As to common parlance, few in 1964 (or today) would de-
scribe a firing because of sexual orientation as a firing be-
cause of sex. As commonly understood, sexual orientation
discrimination is distinct from, and not a form of, sex dis-
crimination. The majority opinion acknowledges the com-
mon understanding, noting that the plaintiffs here proba-
bly did not tell their friends that they were fired because of
their sex. Ante, at 16. That observation is clearly correct.
In common parlance, Bostock and Zarda were fired because
they were gay, not because they were men.
 Contrary to the majority opinion’s approach today, this
Court has repeatedly emphasized that common parlance
matters in assessing the ordinary meaning of a statute, be-
cause courts heed how “most people” “would have under-
stood” the text of a statute when enacted. New Prime Inc.
v. Oliveira, 586 U. S. ___ , ___–___ (2019) (slip op., at 6–7);
see Henson v. Santander Consumer USA Inc., 582 U. S. ___ ,
___ (2017) (slip op., at 4) (using a conversation between
friends to demonstrate ordinary meaning); see also Wiscon-
sin Central Ltd. v. United States, 585 U. S. ___ , ___–___

 Consider the employer who has four employees but must
fire two of them for financial reasons. Suppose the four em-
ployees are a straight man, a straight woman, a gay man,
and a lesbian. The employer with animosity against women
(animosity based on sex) will fire the two women. The em-
ployer with animosity against gays (animosity based on sex-
ual orientation) will fire the gay man and the lesbian.
Those are two distinct harms caused by two distinct biases
that have two different outcomes. To treat one as a form of

the other—as the majority opinion does—misapprehends
common language, human psychology, and real life. See
Hively v. Ivy Tech Community College of Ind., 853 F. 3d 339,
363 (CA7 2017) (Sykes, J., dissenting).
 It also rewrites history. Seneca Falls was not Stonewall.
The women’s rights movement was not (and is not) the gay
rights movement, although many people obviously support
or participate in both. So to think that sexual orientation
discrimination is just a form of sex discrimination is not just
a mistake of language and psychology, but also a mistake of
history and sociology.
 Importantly, an overwhelming body of federal law re-
flects and reinforces the ordinary meaning and demon-
strates that sexual orientation discrimination is distinct
from, and not a form of, sex discrimination. Since enacting
Title VII in 1964, Congress has never treated sexual orien-
tation discrimination the same as, or as a form of, sex dis-
crimination. Instead, Congress has consistently treated sex
discrimination and sexual orientation discrimination as le-
gally distinct categories of discrimination.
 Many federal statutes prohibit sex discrimination, and
many federal statutes also prohibit sexual orientation dis-
crimination. But those sexual orientation statutes ex-
pressly prohibit sexual orientation discrimination in addi-
tion to expressly prohibiting sex discrimination. Every
single one. To this day, Congress has never defined sex dis-
crimination to encompass sexual orientation discrimina-
tion. Instead, when Congress wants to prohibit sexual ori-
entation discrimination in addition to sex discrimination,
Congress explicitly refers to sexual orientation discrimina-
tion.5

 That longstanding and widespread congressional prac-

often said, we “usually presume differences in language”
convey “differences in meaning.” Wisconsin Central, 585
U. S., at ___ (slip op., at 4) (internal quotation marks omit-
ted). When Congress chooses distinct phrases to accom-
plish distinct purposes, and does so over and over again for
decades, we may not lightly toss aside all of Congress’s care-
ful handiwork. As Justice Scalia explained for the Court,
“it is not our function” to “treat alike subjects that different
Congresses have chosen to treat differently.” West Virginia

 So it is here. As demonstrated by all of the statutes cov-
ering sexual orientation discrimination, Congress knows
how to prohibit sexual orientation discrimination. So
courts should not read that specific concept into the general
words “discriminate because of sex.” We cannot close our
eyes to the indisputable fact that Congress—for several dec-
ades in a large number of statutes—has identified sex dis-
crimination and sexual orientation discrimination as two
distinct categories.
 Where possible, we also strive to interpret statutes so as
not to create undue surplusage. It is not uncommon to find
some scattered redundancies in statutes. But reading sex
discrimination to encompass sexual orientation discrimina-
tion would cast aside as surplusage the numerous refer-
ences to sexual orientation discrimination sprinkled
throughout the U. S. Code in laws enacted over the last 25
years.
 In short, an extensive body of federal law both reflects
and reinforces the widespread understanding that sexual
orientation discrimination is distinct from, and not a form
of, sex discrimination.
 The story is the same with bills proposed in Congress.
Since the 1970s, Members of Congress have introduced
many bills to prohibit sexual orientation discrimination in
the workplace. Until very recently, all of those bills would
have expressly established sexual orientation as a sepa-
rately proscribed category of discrimination. The bills did
not define sex discrimination to encompass sexual orienta-
tion discrimination.6

 The proposed bills are telling not because they are rele-

tral Bank of Denver, N. A. v. First Interstate Bank of Den-
ver, N. A., 511 U. S. 164 , 186–188 (1994). Rather, the
proposed bills are telling because they, like the enacted
laws, further demonstrate the widespread usage of the Eng-
lish language in the United States: Sexual orientation dis-
crimination is distinct from, and not a form of, sex discrim-
ination.
 Presidential Executive Orders reflect that same common
understanding. In 1967, President Johnson signed an Ex-
ecutive Order prohibiting sex discrimination in federal em-
ployment. In 1969, President Nixon issued a new order that
did the same. Exec. Order No. 11375, 3 CFR 684 (1966–
1970 Comp.); Exec. Order No. 11478, id., at 803. In 1998,
President Clinton charted a new path and signed an Exec-
utive Order prohibiting sexual orientation discrimination
in federal employment. Exec. Order No. 13087, 3 CFR 191

 Like the relevant federal statutes, the 1998 Clinton Ex-
ecutive Order expressly added sexual orientation as a new,
separately prohibited form of discrimination. As Judge
Lynch cogently spelled out, “the Clinton Administration did
not argue that the prohibition of sex discrimination in” the
prior 1969 Executive Order “already banned, or henceforth
would be deemed to ban, sexual orientation discrimina-
tion.” 883 F. 3d, at 152, n. 22 (dissenting opinion). In short,
President Clinton’s 1998 Executive Order indicates that the
Executive Branch, like Congress, has long understood sex-
ual orientation discrimination to be distinct from, and not
a form of, sex discrimination.
 Federal regulations likewise reflect that same under-
standing. The Office of Personnel Management is the fed-
eral agency that administers and enforces personnel rules
across the Federal Government. OPM has issued regula-
tions that “govern . . . the employment practices of the Fed-
eral Government generally, and of individual agencies.” 5
CFR §§300.101 , 300.102 (2019). Like the federal statutes
and the Presidential Executive Orders, those OPM regula-
tions separately prohibit sex discrimination and sexual ori-
entation discrimination.
 The States have proceeded in the same fashion. A major-

 KAVANAUGH, J., dissenting

 That common usage in the States underscores that sex-
ual orientation discrimination is commonly understood as a
legal concept distinct from sex discrimination.
 And it is the common understanding in this Court as well.
Since 1971, the Court has employed rigorous or heightened
constitutional scrutiny of laws that classify on the basis of
sex. See United States v. Virginia, 518 U. S. 515 , 531–533
(1996); J. E. B. v. Alabama ex rel. T. B., 511 U. S. 127 , 136–
137 (1994); Craig v. Boren, 429 U. S. 190 , 197–199 (1976);
Frontiero v. Richardson, 411 U. S. 677 , 682–684 (1973) (plu-
rality opinion); Reed v. Reed, 404 U. S. 71 , 75–77 (1971).
Over the last several decades, the Court has also decided
many cases involving sexual orientation. But in those
cases, the Court never suggested that sexual orientation
discrimination is just a form of sex discrimination. All of
the Court’s cases from Bowers to Romer to Lawrence to
Windsor to Obergefell would have been far easier to analyze
and decide if sexual orientation discrimination were just a
form of sex discrimination and therefore received the same
heightened scrutiny as sex discrimination under the Equal
Protection Clause. See Bowers v. Hardwick, 478 U. S. 186

 Did the Court in all of those sexual orientation cases just
miss that obvious answer—and overlook the fact that sex-
ual orientation discrimination is actually a form of sex dis-
crimination? That seems implausible. Nineteen Justices
have participated in those cases. Not a single Justice stated
or even hinted that sexual orientation discrimination was
just a form of sex discrimination and therefore entitled to
the same heightened scrutiny under the Equal Protection
Clause. The opinions in those five cases contain no trace of
such reasoning. That is presumably because everyone on
this Court, too, has long understood that sexual orientation

discrimination is distinct from, and not a form of, sex dis-
crimination.
 In sum, all of the usual indicators of ordinary meaning—
common parlance, common usage by Congress, the practice
in the Executive Branch, the laws in the States, and the
decisions of this Court—overwhelmingly establish that sex-
ual orientation discrimination is distinct from, and not a
form of, sex discrimination. The usage has been consistent
across decades, in both the federal and state contexts.
 Judge Sykes summarized the law and language this way:
“To a fluent speaker of the English language—then and
now—. . . discrimination ‘because of sex’ is not reasonably
understood to include discrimination based on sexual orien-
tation, a different immutable characteristic. Classifying
people by sexual orientation is different than classifying
them by sex. The two traits are categorically distinct and
widely recognized as such. There is no ambiguity or vague-
ness here.” Hively, 853 F. 3d, at 363 (dissenting opinion).
 To tie it all together, the plaintiffs have only two routes
to succeed here. Either they can say that literal meaning
overrides ordinary meaning when the two conflict. Or they
can say that the ordinary meaning of the phrase “discrimi-
nate because of sex” encompasses sexual orientation dis-
crimination. But the first flouts long-settled principles of
statutory interpretation. And the second contradicts the
widespread ordinary use of the English language in Amer-
ica.
 II
 Until the last few years, every U. S. Court of Appeals to
address this question concluded that Title VII does not pro-
hibit discrimination because of sexual orientation. As noted
above, in the first 10 Courts of Appeals to consider the is-
sue, all 30 federal judges agreed that Title VII does not pro-
hibit sexual orientation discrimination. 30 out of 30

judges.9
 The unanimity of those 30 federal judges shows that the
question as a matter of law, as compared to as a matter of
policy, was not deemed close. Those 30 judges realized a
seemingly obvious point: Title VII is not a general grant of
authority for judges to fashion an evolving common law of
equal treatment in the workplace. Rather, Title VII identi-
fies certain specific categories of prohibited discrimination.
And under the separation of powers, Congress—not the
courts—possesses the authority to amend or update the
law, as Congress has done with age discrimination and dis-
ability discrimination, for example.
 So what changed from the situation only a few years ago
when 30 out of 30 federal judges had agreed on this ques-
tion? Not the text of Title VII. The law has not changed.
Rather, the judges’ decisions have evolved.
 To be sure, the majority opinion today does not openly
profess that it is judicially updating or amending Title VII.
Cf. Hively, 853 F. 3d, at 357 (Posner, J., concurring). But
the majority opinion achieves the same outcome by seizing
on literal meaning and overlooking the ordinary meaning of
the phrase “discriminate because of sex.” Although the ma-
jority opinion acknowledges that the meaning of a phrase
and the meaning of a phrase’s individual words could differ,
it dismisses phrasal meaning for purposes of this case. The
majority opinion repeatedly seizes on the meaning of the

statute’s individual terms, mechanically puts them back to-
gether, and generates an interpretation of the phrase “dis-
criminate because of sex” that is literal. See ante, at 5–9,
17, 24–26. But to reiterate, that approach to statutory in-
terpretation is fundamentally flawed. Bedrock principles of
statutory interpretation dictate that we look to ordinary
meaning, not literal meaning, and that we likewise adhere
to the ordinary meaning of phrases, not just the meaning of
words in a phrase. And the ordinary meaning of the phrase
“discriminate because of sex” does not encompass sexual
orientation discrimination.
 The majority opinion deflects that critique by saying that
courts should base their interpretation of statutes on the
text as written, not on the legislators’ subjective intentions.
Ante, at 20, 23–30. Of course that is true. No one disagrees.
It is “the provisions of our laws rather than the principal
concerns of our legislators by which we are governed.” On-
cale v. Sundowner Offshore Services, Inc., 523 U. S. 75, 79 
(1998).
 But in my respectful view, the majority opinion makes a
fundamental mistake by confusing ordinary meaning with
subjective intentions. To briefly explain: In the early years
after Title VII was enacted, some may have wondered
whether Title VII’s prohibition on sex discrimination pro-
tected male employees. After all, covering male employees
may not have been the intent of some who voted for the stat-
ute. Nonetheless, discrimination on the basis of sex against
women and discrimination on the basis of sex against men
are both understood as discrimination because of sex (back
in 1964 and now) and are therefore encompassed within Ti-
tle VII. Cf. id., at 78–79; see Newport News Shipbuilding
& Dry Dock Co. v. EEOC, 462 U. S. 669 , 682–685 (1983). So
too, regardless of what the intentions of the drafters might
have been, the ordinary meaning of the law demonstrates
that harassing an employee because of her sex is discrimi-
nating against the employee because of her sex with respect
24 BOSTOCK v. CLAYTON COUNTY

 KAVANAUGH, J., dissenting

to the “terms, conditions, or privileges of employment,” as
this Court rightly concluded. Meritor Savings Bank, FSB
v. Vinson, 477 U. S. 57, 64 (1986) (internal quotation marks
omitted).10
 By contrast, this case involves sexual orientation discrim-
ination, which has long and widely been understood as dis-
tinct from, and not a form of, sex discrimination. Until now,
federal law has always reflected that common usage and
recognized that distinction between sex discrimination and
sexual orientation discrimination. To fire one employee be-
cause she is a woman and another employee because he is
gay implicates two distinct societal concerns, reveals two
distinct biases, imposes two distinct harms, and falls within
two distinct statutory prohibitions.

 10 An amicus brief supporting the plaintiffs suggests that the plaintiffs’

interpretive approach is supported by the interpretive approach em-
ployed by the Court in its landmark decision in Brown v. Board of Edu-
cation, 347 U. S. 483 (1954). See Brief for Anti-Discrimination Scholars
as Amici Curiae 4. That suggestion is incorrect. Brown is a correct de-
cision as a matter of original public meaning. There were two analytical
components of Brown. One issue was the meaning of “equal protection.”
The Court determined that black Americans—like all Americans—have
an individual equal protection right against state discrimination on the
basis of race. (That point is also directly made in Bolling v. Sharpe, 347
U. S. 497 , 499–500 (1954).) Separate but equal is not equal. The other
issue was whether that racial nondiscrimination principle applied to
public schools, even though public schools did not exist in any compara-
ble form in 1868. The answer was yes. The Court applied the equal
protection principle to public schools in the same way that the Court ap-
plies, for example, the First Amendment to the Internet and the Fourth
Amendment to cars.
 This case raises the same kind of inquiry as the first question in
Brown. There, the question was what equal protection meant. Here, the
question is what “discriminate because of sex” means. If this case raised
the question whether the sex discrimination principle in Title VII applied
to some category of employers unknown in 1964, such as to social media
companies, it might be a case in Brown’s second category, akin to the
question whether the racial nondiscrimination principle applied to public
schools. But that is not this case.

 To be sure, as Judge Lynch appropriately recognized, it
is “understandable” that those seeking legal protection for
gay people “search for innovative arguments to classify
workplace bias against gays as a form of discrimination
that is already prohibited by federal law. But the argu-
ments advanced by the majority ignore the evident mean-
ing of the language of Title VII, the social realities that dis-
tinguish between the kinds of biases that the statute sought
to exclude from the workplace from those it did not, and the
distinctive nature of anti-gay prejudice.” 883 F. 3d, at 162 
(dissenting opinion).
 The majority opinion insists that it is not rewriting or up-
dating Title VII, but instead is just humbly reading the text
of the statute as written. But that assertion is tough to ac-
cept. Most everyone familiar with the use of the English
language in America understands that the ordinary mean-
ing of sexual orientation discrimination is distinct from the
ordinary meaning of sex discrimination. Federal law dis-
tinguishes the two. State law distinguishes the two. This
Court’s cases distinguish the two. Statistics on discrimina-
tion distinguish the two. History distinguishes the two.
Psychology distinguishes the two. Sociology distinguishes
the two. Human resources departments all over America
distinguish the two. Sports leagues distinguish the two.
Political groups distinguish the two. Advocacy groups dis-
tinguish the two. Common parlance distinguishes the two.
Common sense distinguishes the two.
 As a result, many Americans will not buy the novel inter-
pretation unearthed and advanced by the Court today.
Many will no doubt believe that the Court has unilaterally
rewritten American vocabulary and American law—a “stat-
utory amendment courtesy of unelected judges.” Hively,
 853 F. 3d, at 360 (Sykes, J., dissenting). Some will surmise
that the Court succumbed to “the natural desire that be-
guiles judges along with other human beings into imposing
their own views of goodness, truth, and justice upon others.”

 I have the greatest, and unyielding, respect for my col-
leagues and for their good faith. But when this Court
usurps the role of Congress, as it does today, the public un-
derstandably becomes confused about who the policymak-
ers really are in our system of separated powers, and inev-
itably becomes cynical about the oft-repeated aspiration
that judges base their decisions on law rather than on per-
sonal preference. The best way for judges to demonstrate
that we are deciding cases based on the ordinary meaning
of the law is to walk the walk, even in the hard cases when
we might prefer a different policy outcome.
 * * *
 In judicially rewriting Title VII, the Court today cashiers
an ongoing legislative process, at a time when a new law to
prohibit sexual orientation discrimination was probably
close at hand. After all, even back in 2007—a veritable life-
time ago in American attitudes about sexual orientation—
the House voted 235 to 184 to prohibit sexual orientation
discrimination in employment. H. R. 3685, 110th Cong., 1st
Sess. In 2013, the Senate overwhelmingly approved a sim-
ilar bill, 64 to 32. S. 815, 113th Cong., 1st Sess. In 2019,
the House voted 236 to 173 to amend Title VII to prohibit
employment discrimination on the basis of sexual orienta-
tion. H. R. 5, 116th Cong., 1st Sess. It was therefore easy
to envision a day, likely just in the next few years, when the
House and Senate took historic votes on a bill that would
prohibit employment discrimination on the basis of sexual
orientation. It was easy to picture a massive and celebra-
tory Presidential signing ceremony in the East Room or on
the South Lawn.
 It is true that meaningful legislative action takes time—
often too much time, especially in the unwieldy morass on

Capitol Hill. But the Constitution does not put the Legis-
lative Branch in the “position of a television quiz show con-
testant so that when a given period of time has elapsed and
a problem remains unsolved by them, the federal judiciary
may press a buzzer and take its turn at fashioning a solu-
tion.” Rehnquist, The Notion of a Living Constitution, 54
Texas L. Rev. 693, 700 (1976). The proper role of the Judi-
ciary in statutory interpretation cases is “to apply, not
amend, the work of the People’s representatives,” even
when the judges might think that “Congress should reenter
the field and alter the judgments it made in the past.” Hen-
son, 582 U. S., at ___–___ (slip op., at 10–11).
 Instead of a hard-earned victory won through the demo-
cratic process, today’s victory is brought about by judicial
dictate—judges latching on to a novel form of living literal-
ism to rewrite ordinary meaning and remake American law.
Under the Constitution and laws of the United States, this
Court is the wrong body to change American law in that
way. The Court’s ruling “comes at a great cost to repre-
sentative self-government.” Hively, 853 F. 3d, at 360 
(Sykes, J., dissenting). And the implications of this Court’s
usurpation of the legislative process will likely reverberate
in unpredictable ways for years to come.
 Notwithstanding my concern about the Court’s trans-
gression of the Constitution’s separation of powers, it is ap-
propriate to acknowledge the important victory achieved to-
day by gay and lesbian Americans. Millions of gay and
lesbian Americans have worked hard for many decades to
achieve equal treatment in fact and in law. They have ex-
hibited extraordinary vision, tenacity, and grit—battling of-
ten steep odds in the legislative and judicial arenas, not to
mention in their daily lives. They have advanced powerful
policy arguments and can take pride in today’s result. Un-
der the Constitution’s separation of powers, however, I be-
lieve that it was Congress’s role, not this Court’s, to amend
Title VII. I therefore must respectfully dissent from the

Court’s judgment.

Justice GORSUCH delivered the opinion of the Court.
 *1737 Sometimes small gestures can have unexpected consequences. Major initiatives practically guarantee them. In our time, few pieces of federal legislation rank in significance with the Civil Rights Act of 1964. There, in Title VII, Congress outlawed discrimination in the workplace on the basis of race, color, religion, sex, or national origin. Today, we must decide whether an employer can fire someone simply for being homosexual or transgender. The answer is clear. An employer who fires an individual for being homosexual or transgender fires that person for traits or actions it would not have questioned in members of a different sex. Sex plays a necessary and undisguisable role in the decision, exactly what Title VII forbids.

 Those who adopted the Civil Rights Act might not have anticipated their work would lead to this particular result. Likely, they weren't thinking about many of the Act's consequences that have become apparent over the years, including its prohibition against discrimination on the basis of motherhood or its ban on the sexual harassment of male employees. But the limits of the drafters' imagination supply no reason to ignore the law's demands. When the express terms of a statute give us one answer and extratextual considerations suggest another, it's no contest. Only the written word is the law, and all persons are entitled to its benefit.

 I

 Few facts are needed to appreciate the legal question we face. Each of the three cases before us started the same way: An employer fired a long-time employee shortly after the employee revealed that he or she is homosexual or transgender-and allegedly for no reason other than the employee's homosexuality or transgender status.

 Gerald Bostock worked for Clayton County, Georgia, as a child welfare advocate. Under his leadership, the county won national awards for its work. After a decade with the county, Mr. Bostock began participating in a gay recreational softball league. Not long after that, influential *1738 members of the community allegedly made disparaging comments about Mr. Bostock's sexual orientation and participation in the league. Soon, he was fired for conduct "unbecoming" a county employee.

 Donald Zarda worked as a skydiving instructor at Altitude Express in New York. After several seasons with the company, Mr. Zarda mentioned that he was gay and, days later, was fired.

 Aimee Stephens worked at R.G. & G.R. Harris Funeral Homes in Garden City, Michigan. When she got the job, Ms. Stephens presented as a male. But two years into her service with the company, she began treatment for despair and loneliness. Ultimately, clinicians diagnosed her with gender dysphoria and recommended that she begin living as a woman. In her sixth year with the company, Ms. Stephens wrote a letter to her employer explaining that she planned to " live and work full-time as a woman" after she returned from an upcoming vacation. The funeral home fired her before she left, telling her "this is not going to work out."

 While these cases began the same way, they ended differently. Each employee brought suit under Title VII alleging unlawful discrimination on the basis of sex. 78 Stat. 255 , 42 U.S.C. § 2000e-2(a)(1). In Mr. Bostock's case, the Eleventh Circuit held that the law does not prohibit employers from firing employees for being gay and so his suit could be dismissed as a matter of law. 723 Fed.Appx. 964 (2018). Meanwhile, in Mr. Zarda's case, the Second Circuit concluded that sexual orientation discrimination does violate Title VII and allowed his case to proceed. 883 F.3d 100 (2018). Ms. Stephens's case has a more complex procedural history, but in the end the Sixth Circuit reached a decision along the same lines as the Second Circuit's, holding that Title VII bars employers from firing employees because of their transgender status. 884 F.3d 560 (2018). During the course of the proceedings in these long-running disputes, both Mr. Zarda and Ms. Stephens have passed away. But their estates continue to press their causes for the benefit of their heirs. And we granted certiorari in these matters to resolve at last the disagreement among the courts of appeals over the scope of Title VII's protections for homosexual and transgender persons. 587 U.S. ----, 139 S.Ct. 1599 , 203 L.Ed.2d 754 (2019).

 II

 This Court normally interprets a statute in accord with the ordinary public meaning of its terms at the time of its enactment. After all, only the words on the page constitute the law adopted by Congress and approved by the President. If judges could add to, remodel, update, or detract from old statutory terms inspired only by extratextual sources and our own imaginations, we would risk amending statutes outside the legislative process reserved for the people's representatives. And we would deny the people the right to continue relying on the original meaning of the law they have counted on to settle their rights and obligations. See New Prime Inc. v. Oliveira , 586 U.S. ----, ---- - ----, 139 S.Ct. 532 , 538-539, 202 L.Ed.2d 536 (2019).

 With this in mind, our task is clear. We must determine the ordinary public meaning of Title VII's command that it is "unlawful ... for an employer to fail or refuse to hire or to discharge any individual, or otherwise to discriminate against any individual with respect to his compensation, terms, conditions, or privileges of employment, because of such individual's race, color, religion, sex, or national origin." § 2000e-2(a)(1). To do so, we orient ourselves to the time of the statute's adoption, here 1964, and begin by examining *1739 the key statutory terms in turn before assessing their impact on the cases at hand and then confirming our work against this Court's precedents.

 A

 The only statutorily protected characteristic at issue in today's cases is "sex"-and that is also the primary term in Title VII whose meaning the parties dispute. Appealing to roughly contemporaneous dictionaries, the employers say that, as used here, the term "sex" in 1964 referred to "status as either male or female [as] determined by reproductive biology." The employees counter by submitting that, even in 1964, the term bore a broader scope, capturing more than anatomy and reaching at least some norms concerning gender identity and sexual orientation. But because nothing in our approach to these cases turns on the outcome of the parties' debate, and because the employees concede the point for argument's sake, we proceed on the assumption that "sex" signified what the employers suggest, referring only to biological distinctions between male and female.

 Still, that's just a starting point. The question isn't just what "sex" meant, but what Title VII says about it. Most notably, the statute prohibits employers from taking certain actions "because of " sex. And, as this Court has previously explained, "the ordinary meaning of 'because of' is 'by reason of' or 'on account of.' " University of Tex. Southwestern Medical Center v. Nassar , 570 U.S. 338 , 350, 133 S.Ct. 2517 , 186 L.Ed.2d 503 (2013) (citing Gross v. FBL Financial Services, Inc. , 557 U.S. 167 , 176, 129 S.Ct. 2343 , 174 L.Ed.2d 119 (2009) ; quotation altered). In the language of law, this means that Title VII's "because of " test incorporates the " 'simple' " and "traditional" standard of but-for causation. Nassar , 570 U.S. at 346 , 360 , 133 S.Ct. 2517 . That form of causation is established whenever a particular outcome would not have happened "but for" the purported cause. See Gross , 557 U.S. at 176 , 129 S.Ct. 2343 . In other words, a but-for test directs us to change one thing at a time and see if the outcome changes. If it does, we have found a but-for cause.

 This can be a sweeping standard. Often, events have multiple but-for causes. So, for example, if a car accident occurred both because the defendant ran a red light and because the plaintiff failed to signal his turn at the intersection, we might call each a but-for cause of the collision. Cf. Burrage v. United States , 571 U.S. 204 , 211-212, 134 S.Ct. 881 , 187 L.Ed.2d 715 (2014). When it comes to Title VII, the adoption of the traditional but-for causation standard means a defendant cannot avoid liability just by citing some other factor that contributed to its challenged employment decision. So long as the plaintiff 's sex was one but-for cause of that decision, that is enough to trigger the law. See ibid . ; Nassar , 570 U.S. at 350 , 133 S.Ct. 2517 .

 No doubt, Congress could have taken a more parsimonious approach. As it has in other statutes, it could have added "solely" to indicate that actions taken "because of " the confluence of multiple factors do not violate the law. Cf. 11 U.S.C. § 525 ; 16 U.S.C. § 511 . Or it could have written "primarily because of " to indicate that the prohibited factor had to be the main cause of the defendant's challenged employment decision. Cf. 22 U.S.C. § 2688 . But none of this is the law we have. If anything, Congress has moved in the opposite direction, supplementing Title VII in 1991 to allow a plaintiff to prevail merely by showing that a protected trait like sex was a "motivating factor" in a defendant's challenged employment practice. Civil Rights Act of 1991, § 107, 105 Stat. 1075 , codified at *1740 42 U.S.C. § 2000e-2(m). Under this more forgiving standard, liability can sometimes follow even if sex wasn't a but-for cause of the employer's challenged decision. Still, because nothing in our analysis depends on the motivating factor test, we focus on the more traditional but-for causation standard that continues to afford a viable, if no longer exclusive, path to relief under Title VII. § 2000e-2(a)(1).

 As sweeping as even the but-for causation standard can be, Title VII does not concern itself with everything that happens "because of " sex. The statute imposes liability on employers only when they "fail or refuse to hire," "discharge," "or otherwise ... discriminate against" someone because of a statutorily protected characteristic like sex. Ibid. The employers acknowledge that they discharged the plaintiffs in today's cases, but assert that the statute's list of verbs is qualified by the last item on it: "otherwise ... discriminate against." By virtue of the word otherwise , the employers suggest, Title VII concerns itself not with every discharge, only with those discharges that involve discrimination.

 Accepting this point, too, for argument's sake, the question becomes: What did "discriminate" mean in 1964? As it turns out, it meant then roughly what it means today: "To make a difference in treatment or favor (of one as compared with others)." Webster's New International Dictionary 745 (2d ed. 1954). To "discriminate against" a person, then, would seem to mean treating that individual worse than others who are similarly situated. See Burlington N. & S. F. R. Co. v. White , 548 U.S. 53 , 59, 126 S.Ct. 2405 , 165 L.Ed.2d 345 (2006). In so-called "disparate treatment" cases like today's, this Court has also held that the difference in treatment based on sex must be intentional. See, e.g., Watson v. Fort Worth Bank & Trust , 487 U.S. 977 , 986, 108 S.Ct. 2777 , 101 L.Ed.2d 827 (1988). So, taken together, an employer who intentionally treats a person worse because of sex-such as by firing the person for actions or attributes it would tolerate in an individual of another sex-discriminates against that person in violation of Title VII.

 At first glance, another interpretation might seem possible. Discrimination sometimes involves "the act, practice, or an instance of discriminating categorically rather than individually." Webster's New Collegiate Dictionary 326 (1975); see also post, at 1768- 1769, n. 22 (ALITO, J., dissenting). On that understanding, the statute would require us to consider the employer's treatment of groups rather than individuals, to see how a policy affects one sex as a whole versus the other as a whole. That idea holds some intuitive appeal too. Maybe the law concerns itself simply with ensuring that employers don't treat women generally less favorably than they do men. So how can we tell which sense, individual or group, "discriminate" carries in Title VII?

 The statute answers that question directly. It tells us three times-including immediately after the words "discriminate against"-that our focus should be on individuals, not groups: Employers may not "fail or refuse to hire or ... discharge any individual , or otherwise ... discriminate against any individual with respect to his compensation, terms, conditions, or privileges of employment, because of such individual's ... sex." § 2000e-2(a)(1) (emphasis added). And the meaning of "individual" was as uncontroversial in 1964 as it is today: "A particular being as distinguished from a class, species, or collection." Webster's New International Dictionary, at 1267. Here, again, Congress could have written the law differently. It might have said that "it shall be an unlawful employment *1741 practice to prefer one sex to the other in hiring, firing, or the terms or conditions of employment." It might have said that there should be no "sex discrimination," perhaps implying a focus on differential treatment between the two sexes as groups. More narrowly still, it could have forbidden only "sexist policies" against women as a class. But, once again, that is not the law we have.

 The consequences of the law's focus on individuals rather than groups are anything but academic. Suppose an employer fires a woman for refusing his sexual advances. It's no defense for the employer to note that, while he treated that individual woman worse than he would have treated a man, he gives preferential treatment to female employees overall. The employer is liable for treating this woman worse in part because of her sex. Nor is it a defense for an employer to say it discriminates against both men and women because of sex. This statute works to protect individuals of both sexes from discrimination, and does so equally. So an employer who fires a woman, Hannah, because she is insufficiently feminine and also fires a man, Bob, for being insufficiently masculine may treat men and women as groups more or less equally. But in both cases the employer fires an individual in part because of sex. Instead of avoiding Title VII exposure, this employer doubles it.

 From the ordinary public meaning of the statute's language at the time of the law's adoption, a straightforward rule emerges: An employer violates Title VII when it intentionally fires an individual employee based in part on sex. It doesn't matter if other factors besides the plaintiff 's sex contributed to the decision. And it doesn't matter if the employer treated women as a group the same when compared to men as a group. If the employer intentionally relies in part on an individual employee's sex when deciding to discharge the employee-put differently, if changing the employee's sex would have yielded a different choice by the employer-a statutory violation has occurred. Title VII's message is "simple but momentous": An individual employee's sex is "not relevant to the selection, evaluation, or compensation of employees." Price Waterhouse v. Hopkins , 490 U.S. 228 , 239, 109 S.Ct. 1775 , 104 L.Ed.2d 268 (1989) (plurality opinion).

 The statute's message for our cases is equally simple and momentous: An individual's homosexuality or transgender status is not relevant to employment decisions. That's because it is impossible to discriminate against a person for being homosexual or transgender without discriminating against that individual based on sex. Consider, for example, an employer with two employees, both of whom are attracted to men. The two individuals are, to the employer's mind, materially identical in all respects, except that one is a man and the other a woman. If the employer fires the male employee for no reason other than the fact he is attracted to men, the employer discriminates against him for traits or actions it tolerates in his female colleague. Put differently, the employer intentionally singles out an employee to fire based in part on the employee's sex, and the affected employee's sex is a but-for cause of his discharge. Or take an employer who fires a transgender person who was identified as a male at birth but who now identifies as a female. If the employer retains an otherwise identical employee who was identified as female at birth, the employer intentionally penalizes a person identified as male at birth for traits or actions that it tolerates in an employee identified as female at birth. Again, the individual employee's sex plays an unmistakable *1742 and impermissible role in the discharge decision.

 That distinguishes these cases from countless others where Title VII has nothing to say. Take an employer who fires a female employee for tardiness or incompetence or simply supporting the wrong sports team. Assuming the employer would not have tolerated the same trait in a man, Title VII stands silent. But unlike any of these other traits or actions, homosexuality and transgender status are inextricably bound up with sex. Not because homosexuality or transgender status are related to sex in some vague sense or because discrimination on these bases has some disparate impact on one sex or another, but because to discriminate on these grounds requires an employer to intentionally treat individual employees differently because of their sex.

 Nor does it matter that, when an employer treats one employee worse because of that individual's sex, other factors may contribute to the decision. Consider an employer with a policy of firing any woman he discovers to be a Yankees fan. Carrying out that rule because an employee is a woman and a fan of the Yankees is a firing "because of sex" if the employer would have tolerated the same allegiance in a male employee. Likewise here. When an employer fires an employee because she is homosexual or transgender, two causal factors may be in play- both the individual's sex and something else (the sex to which the individual is attracted or with which the individual identifies). But Title VII doesn't care. If an employer would not have discharged an employee but for that individual's sex, the statute's causation standard is met, and liability may attach.

 Reframing the additional causes in today's cases as additional intentions can do no more to insulate the employers from liability. Intentionally burning down a neighbor's house is arson, even if the perpetrator's ultimate intention (or motivation) is only to improve the view. No less, intentional discrimination based on sex violates Title VII, even if it is intended only as a means to achieving the employer's ultimate goal of discriminating against homosexual or transgender employees. There is simply no escaping the role intent plays here: Just as sex is necessarily a but-for cause when an employer discriminates against homosexual or transgender employees, an employer who discriminates on these grounds inescapably intends to rely on sex in its decisionmaking. Imagine an employer who has a policy of firing any employee known to be homosexual. The employer hosts an office holiday party and invites employees to bring their spouses. A model employee arrives and introduces a manager to Susan, the employee's wife. Will that employee be fired? If the policy works as the employer intends, the answer depends entirely on whether the model employee is a man or a woman. To be sure, that employer's ultimate goal might be to discriminate on the basis of sexual orientation. But to achieve that purpose the employer must, along the way, intentionally treat an employee worse based in part on that individual's sex.

 An employer musters no better a defense by responding that it is equally happy to fire male and female employees who are homosexual or transgender. Title VII liability is not limited to employers who, through the sum of all of their employment actions, treat the class of men differently than the class of women. Instead, the law makes each instance of discriminating against an individual employee because of that individual's sex an independent violation of Title VII. So just as an employer who fires both Hannah and Bob for failing to fulfill traditional sex stereotypes doubles rather than eliminates Title *1743 VII liability, an employer who fires both Hannah and Bob for being gay or transgender does the same.

 At bottom, these cases involve no more than the straightforward application of legal terms with plain and settled meanings. For an employer to discriminate against employees for being homosexual or transgender, the employer must intentionally discriminate against individual men and women in part because of sex. That has always been prohibited by Title VII's plain terms-and that "should be the end of the analysis." 883 F.3d at 135 (Cabranes, J., concurring in judgment).

 C

 If more support for our conclusion were required, there's no need to look far. All that the statute's plain terms suggest, this Court's cases have already confirmed. Consider three of our leading precedents.

 In Phillips v. Martin Marietta Corp. , 400 U.S. 542 , 91 S.Ct. 496 , 27 L.Ed.2d 613 (1971) ( per curiam ), a company allegedly refused to hire women with young children, but did hire men with children the same age. Because its discrimination depended not only on the employee's sex as a female but also on the presence of another criterion-namely, being a parent of young children-the company contended it hadn't engaged in discrimination "because of " sex. The company maintained, too, that it hadn't violated the law because, as a whole, it tended to favor hiring women over men. Unsurprisingly by now, these submissions did not sway the Court. That an employer discriminates intentionally against an individual only in part because of sex supplies no defense to Title VII. Nor does the fact an employer may happen to favor women as a class.

 In Los Angeles Dept. of Water and Power v. Manhart , 435 U.S. 702 , 98 S.Ct. 1370 , 55 L.Ed.2d 657 (1978), an employer required women to make larger pension fund contributions than men. The employer sought to justify its disparate treatment on the ground that women tend to live longer than men, and thus are likely to receive more from the pension fund over time. By everyone's admission, the employer was not guilty of animosity against women or a "purely habitual assumptio[n] about a woman's inability to perform certain kinds of work"; instead, it relied on what appeared to be a statistically accurate statement about life expectancy. Id. , at 707-708, 98 S.Ct. 1370 . Even so, the Court recognized, a rule that appears evenhanded at the group level can prove discriminatory at the level of individuals. True, women as a class may live longer than men as a class. But "[t]he statute's focus on the individual is unambiguous," and any individual woman might make the larger pension contributions and still die as early as a man. Id. , at 708, 98 S.Ct. 1370 . Likewise, the Court dismissed as irrelevant the employer's insistence that its actions were motivated by a wish to achieve classwide equality between the sexes: An employer's intentional discrimination on the basis of sex is no more permissible when it is prompted by some further intention (or motivation), even one as prosaic as seeking to account for actuarial tables. Ibid. The employer violated Title VII because, when its policy worked exactly as planned, it could not "pass the simple test" asking whether an individual female employee would have been treated the same regardless of her sex. Id. , at 711, 98 S.Ct. 1370 .

 In Oncale v. Sundowner Offshore Services, Inc. , 523 U.S. 75 , 118 S.Ct. 998 , 140 L.Ed.2d 201 (1998), a male plaintiff alleged that he was singled out by his male co-workers for sexual harassment. The Court held it was immaterial that members of the same sex as the victim committed the alleged discrimination. Nor did the Court *1744 concern itself with whether men as a group were subject to discrimination or whether something in addition to sex contributed to the discrimination, like the plaintiff 's conduct or personal attributes. "[A]ssuredly," the case didn't involve "the principal evil Congress was concerned with when it enacted Title VII." Id. , at 79, 118 S.Ct. 998 . But, the Court unanimously explained, it is "the provisions of our laws rather than the principal concerns of our legislators by which we are governed." Ibid. Because the plaintiff alleged that the harassment would not have taken place but for his sex-that is, the plaintiff would not have suffered similar treatment if he were female-a triable Title VII claim existed.

 The lessons these cases hold for ours are by now familiar.

 First, it's irrelevant what an employer might call its discriminatory practice, how others might label it, or what else might motivate it. In Manhart , the employer called its rule requiring women to pay more into the pension fund a "life expectancy" adjustment necessary to achieve sex equality. In Phillips , the employer could have accurately spoken of its policy as one based on "motherhood." In much the same way, today's employers might describe their actions as motivated by their employees' homosexuality or transgender status. But just as labels and additional intentions or motivations didn't make a difference in Manhart or Phillips , they cannot make a difference here. When an employer fires an employee for being homosexual or transgender, it necessarily and intentionally discriminates against that individual in part because of sex. And that is all Title VII has ever demanded to establish liability.

 Second, the plaintiff 's sex need not be the sole or primary cause of the employer's adverse action. In Phillips , Manhart , and Oncale , the defendant easily could have pointed to some other, nonprotected trait and insisted it was the more important factor in the adverse employment outcome. So, too, it has no significance here if another factor-such as the sex the plaintiff is attracted to or presents as-might also be at work, or even play a more important role in the employer's decision.

 Finally, an employer cannot escape liability by demonstrating that it treats males and females comparably as groups. As Manhart teaches, an employer is liable for intentionally requiring an individual female employee to pay more into a pension plan than a male counterpart even if the scheme promotes equality at the group level. Likewise, an employer who intentionally fires an individual homosexual or transgender employee in part because of that individual's sex violates the law even if the employer is willing to subject all male and female homosexual or transgender employees to the same rule.

 III

 What do the employers have to say in reply? For present purposes, they do not dispute that they fired the plaintiffs for being homosexual or transgender. Sorting out the true reasons for an adverse employment decision is often a hard business, but none of that is at issue here. Rather, the employers submit that even intentional discrimination against employees based on their homosexuality or transgender status supplies no basis for liability under Title VII.

 The employers' argument proceeds in two stages. Seeking footing in the statutory text, they begin by advancing a number of reasons why discrimination on the basis of homosexuality or transgender status doesn't involve discrimination because of sex. But each of these arguments turns out only to repackage errors we've already *1745 seen and this Court's precedents have already rejected. In the end, the employers are left to retreat beyond the statute's text, where they fault us for ignoring the legislature's purposes in enacting Title VII or certain expectations about its operation. They warn, too, about consequences that might follow a ruling for the employees. But none of these contentions about what the employers think the law was meant to do, or should do, allow us to ignore the law as it is.

 A

 Maybe most intuitively, the employers assert that discrimination on the basis of homosexuality and transgender status aren't referred to as sex discrimination in ordinary conversation. If asked by a friend (rather than a judge) why they were fired, even today's plaintiffs would likely respond that it was because they were gay or transgender, not because of sex. According to the employers, that conversational answer, not the statute's strict terms, should guide our thinking and suffice to defeat any suggestion that the employees now before us were fired because of sex. Cf. post, at 1755 - 1756 (ALITO, J., dissenting); post, at 1826 - 1829 (KAVANAUGH, J., dissenting).

 But this submission rests on a mistaken understanding of what kind of cause the law is looking for in a Title VII case. In conversation, a speaker is likely to focus on what seems most relevant or informative to the listener. So an employee who has just been fired is likely to identify the primary or most direct cause rather than list literally every but-for cause. To do otherwise would be tiring at best. But these conversational conventions do not control Title VII's legal analysis, which asks simply whether sex was a but-for cause. In Phillips , for example, a woman who was not hired under the employer's policy might have told her friends that her application was rejected because she was a mother, or because she had young children. Given that many women could be hired under the policy, it's unlikely she would say she was not hired because she was a woman. But the Court did not hesitate to recognize that the employer in Phillips discriminated against the plaintiff because of her sex. Sex wasn't the only factor, or maybe even the main factor, but it was one but-for cause-and that was enough. You can call the statute's but-for causation test what you will-expansive, legalistic, the dissents even dismiss it as wooden or literal. But it is the law.

 Trying another angle, the defendants before us suggest that an employer who discriminates based on homosexuality or transgender status doesn't intentionally discriminate based on sex, as a disparate treatment claim requires. See post , at 1758 - 1760 (ALITO, J., dissenting); post , at 1828 - 1829 (KAVANAUGH, J., dissenting). But, as we've seen, an employer who discriminates against homosexual or transgender employees necessarily and intentionally applies sex-based rules. An employer that announces it will not employ anyone who is homosexual, for example, intends to penalize male employees for being attracted to men and female employees for being attracted to women.

 What, then, do the employers mean when they insist intentional discrimination based on homosexuality or transgender status isn't intentional discrimination based on sex? Maybe the employers mean they don't intend to harm one sex or the other as a class. But as should be clear by now, the statute focuses on discrimination against individuals, not groups. Alternatively, the employers may mean that they don't perceive themselves as motivated by a desire to discriminate based on sex. But nothing in Title VII turns on the employer's *1746 labels or any further intentions (or motivations) for its conduct beyond sex discrimination. In Manhart , the employer intentionally required women to make higher pension contributions only to fulfill the further purpose of making things more equitable between men and women as groups. In Phillips , the employer may have perceived itself as discriminating based on motherhood, not sex, given that its hiring policies as a whole favored women. But in both cases, the Court set all this aside as irrelevant. The employers' policies involved intentional discrimination because of sex, and Title VII liability necessarily followed.

 Aren't these cases different, the employers ask, given that an employer could refuse to hire a gay or transgender individual without ever learning the applicant's sex? Suppose an employer asked homosexual or transgender applicants to tick a box on its application form. The employer then had someone else redact any information that could be used to discern sex. The resulting applications would disclose which individuals are homosexual or transgender without revealing whether they also happen to be men or women. Doesn't that possibility indicate that the employer's discrimination against homosexual or transgender persons cannot be sex discrimination?

 No, it doesn't. Even in this example, the individual applicant's sex still weighs as a factor in the employer's decision. Change the hypothetical ever so slightly and its flaws become apparent. Suppose an employer's application form offered a single box to check if the applicant is either black or Catholic. If the employer refuses to hire anyone who checks that box, would we conclude the employer has complied with Title VII, so long as it studiously avoids learning any particular applicant's race or religion? Of course not: By intentionally setting out a rule that makes hiring turn on race or religion, the employer violates the law, whatever he might know or not know about individual applicants.

 The same holds here. There is no way for an applicant to decide whether to check the homosexual or transgender box without considering sex. To see why, imagine an applicant doesn't know what the words homosexual or transgender mean. Then try writing out instructions for who should check the box without using the words man, woman, or sex (or some synonym). It can't be done. Likewise, there is no way an employer can discriminate against those who check the homosexual or transgender box without discriminating in part because of an applicant's sex. By discriminating against homosexuals, the employer intentionally penalizes men for being attracted to men and women for being attracted to women. By discriminating against transgender persons, the employer unavoidably discriminates against persons with one sex identified at birth and another today. Any way you slice it, the employer intentionally refuses to hire applicants in part because of the affected individuals' sex, even if it never learns any applicant's sex.

 Next, the employers turn to Title VII's list of protected characteristics-race, color, religion, sex, and national origin. Because homosexuality and transgender status can't be found on that list and because they are conceptually distinct from sex, the employers reason, they are implicitly excluded from Title VII's reach. Put another way, if Congress had wanted to address these matters in Title VII, it would have referenced them specifically. Cf. post, at 1757 - 1758 (ALITO, J., dissenting); post, at 1828 - 1830 (KAVANAUGH, J., dissenting).

 But that much does not follow. We agree that homosexuality and transgender status are distinct concepts from *1747 sex. But, as we've seen, discrimination based on homosexuality or transgender status necessarily entails discrimination based on sex; the first cannot happen without the second. Nor is there any such thing as a "canon of donut holes," in which Congress's failure to speak directly to a specific case that falls within a more general statutory rule creates a tacit exception. Instead, when Congress chooses not to include any exceptions to a broad rule, courts apply the broad rule. And that is exactly how this Court has always approached Title VII. "Sexual harassment" is conceptually distinct from sex discrimination, but it can fall within Title VII's sweep. Oncale , 523 U.S. at 79 -80 , 118 S.Ct. 998 . Same with "motherhood discrimination." See Phillips , 400 U.S. at 544 , 91 S.Ct. 496 . Would the employers have us reverse those cases on the theory that Congress could have spoken to those problems more specifically? Of course not. As enacted, Title VII prohibits all forms of discrimination because of sex, however they may manifest themselves or whatever other labels might attach to them.

 The employers try the same point another way. Since 1964, they observe, Congress has considered several proposals to add sexual orientation to Title VII's list of protected characteristics, but no such amendment has become law. Meanwhile, Congress has enacted other statutes addressing other topics that do discuss sexual orientation. This postenactment legislative history, they urge, should tell us something. Cf. post , at 1754 - 1755, 1776 - 1778 (ALITO, J., dissenting); post , at 1823 - 1824, 1830 - 1831 (KAVANAUGH, J., dissenting).

 But what? There's no authoritative evidence explaining why later Congresses adopted other laws referencing sexual orientation but didn't amend this one. Maybe some in the later legislatures understood the impact Title VII's broad language already promised for cases like ours and didn't think a revision needed. Maybe others knew about its impact but hoped no one else would notice. Maybe still others, occupied by other concerns, didn't consider the issue at all. All we can know for certain is that speculation about why a later Congress declined to adopt new legislation offers a "particularly dangerous" basis on which to rest an interpretation of an existing law a different and earlier Congress did adopt. Pension Benefit Guaranty Corporation v. LTV Corp. , 496 U.S. 633 , 650, 110 S.Ct. 2668 , 110 L.Ed.2d 579 (1990) ; see also United States v. Wells , 519 U.S. 482 , 496, 117 S.Ct. 921 , 137 L.Ed.2d 107 (1997) ; Sullivan v. Finkelstein , 496 U.S. 617 , 632, 110 S.Ct. 2658 , 110 L.Ed.2d 563 (1990) (Scalia, J., concurring) ("Arguments based on subsequent legislative history ... should not be taken seriously, not even in a footnote").

 That leaves the employers to seek a different sort of exception. Maybe the traditional and simple but-for causation test should apply in all other Title VII cases, but it just doesn't work when it comes to cases involving homosexual and transgender employees. The test is too blunt to capture the nuances here. The employers illustrate their concern with an example. When we apply the simple test to Mr. Bostock-asking whether Mr. Bostock, a man attracted to other men, would have been fired had he been a woman-we don't just change his sex. Along the way, we change his sexual orientation too (from homosexual to heterosexual). If the aim is to isolate whether a plaintiff 's sex caused the dismissal, the employers stress, we must hold sexual orientation constant-meaning we need to change both his sex and the sex to which he is attracted. So for Mr. Bostock, the question should be whether he would've been fired if he were *1748 a woman attracted to women. And because his employer would have been as quick to fire a lesbian as it was a gay man, the employers conclude, no Title VII violation has occurred.

 While the explanation is new, the mistakes are the same. The employers might be onto something if Title VII only ensured equal treatment between groups of men and women or if the statute applied only when sex is the sole or primary reason for an employer's challenged adverse employment action. But both of these premises are mistaken. Title VII's plain terms and our precedents don't care if an employer treats men and women comparably as groups; an employer who fires both lesbians and gay men equally doesn't diminish but doubles its liability. Just cast a glance back to Manhart , where it was no defense that the employer sought to equalize pension contributions based on life expectancy. Nor does the statute care if other factors besides sex contribute to an employer's discharge decision. Mr. Bostock's employer might have decided to fire him only because of the confluence of two factors, his sex and the sex to which he is attracted. But exactly the same might have been said in Phillips , where motherhood was the added variable.

 Still, the employers insist, something seems different here. Unlike certain other employment policies this Court has addressed that harmed only women or only men, the employers' policies in the cases before us have the same adverse consequences for men and women. How could sex be necessary to the result if a member of the opposite sex might face the same outcome from the same policy?

 What the employers see as unique isn't even unusual. Often in life and law two but-for factors combine to yield a result that could have also occurred in some other way. Imagine that it's a nice day outside and your house is too warm, so you decide to open the window. Both the cool temperature outside and the heat inside are but-for causes of your choice to open the window. That doesn't change just because you also would have opened the window had it been warm outside and cold inside. In either case, no one would deny that the window is open "because of" the outside temperature. Our cases are much the same. So, for example, when it comes to homosexual employees, male sex and attraction to men are but-for factors that can combine to get them fired. The fact that female sex and attraction to women can also get an employee fired does no more than show the same outcome can be achieved through the combination of different factors. In either case, though, sex plays an essential but-for role.

 At bottom, the employers' argument unavoidably comes down to a suggestion that sex must be the sole or primary cause of an adverse employment action for Title VII liability to follow. And, as we've seen, that suggestion is at odds with everything we know about the statute. Consider an employer eager to revive the workplace gender roles of the 1950s. He enforces a policy that he will hire only men as mechanics and only women as secretaries. When a qualified woman applies for a mechanic position and is denied, the "simple test" immediately spots the discrimination: A qualified man would have been given the job, so sex was a but-for cause of the employer's refusal to hire. But like the employers before us today, this employer would say not so fast. By comparing the woman who applied to be a mechanic to a man who applied to be a mechanic, we've quietly changed two things: the applicant's sex and her trait of failing to conform to 1950s gender roles. The "simple test" thus overlooks that it is really the applicant's bucking of 1950s gender roles, not her sex, *1749 doing the work. So we need to hold that second trait constant: Instead of comparing the disappointed female applicant to a man who applied for the same position, the employer would say, we should compare her to a man who applied to be a secretary. And because that jobseeker would be refused too, this must not be sex discrimination.

 No one thinks that , so the employers must scramble to justify deploying a stricter causation test for use only in cases involving discrimination based on sexual orientation or transgender status. Such a rule would create a curious discontinuity in our case law, to put it mildly. Employer hires based on sexual stereotypes? Simple test. Employer sets pension contributions based on sex? Simple test. Employer fires men who do not behave in a sufficiently masculine way around the office? Simple test. But when that same employer discriminates against women who are attracted to women, or persons identified at birth as women who later identify as men, we suddenly roll out a new and more rigorous standard? Why are these reasons for taking sex into account different from all the rest? Title VII's text can offer no answer.

 B

 Ultimately, the employers are forced to abandon the statutory text and precedent altogether and appeal to assumptions and policy. Most pointedly, they contend that few in 1964 would have expected Title VII to apply to discrimination against homosexual and transgender persons. And whatever the text and our precedent indicate, they say, shouldn't this fact cause us to pause before recognizing liability?

 It might be tempting to reject this argument out of hand. This Court has explained many times over many years that, when the meaning of the statute's terms is plain, our job is at an end. The people are entitled to rely on the law as written, without fearing that courts might disregard its plain terms based on some extratextual consideration. See, e.g. , Carcieri v. Salazar , 555 U.S. 379 , 387, 129 S.Ct. 1058 , 172 L.Ed.2d 791 (2009) ; Connecticut Nat. Bank v. Germain , 503 U.S. 249 , 253-254, 112 S.Ct. 1146 , 117 L.Ed.2d 391 (1992) ; Rubin v. United States , 449 U.S. 424 , 430, 101 S.Ct. 698 , 66 L.Ed.2d 633 (1981). Of course, some Members of this Court have consulted legislative history when interpreting ambiguous statutory language. Cf. post , at 1775 (ALITO, J., dissenting). But that has no bearing here. "Legislative history, for those who take it into account, is meant to clear up ambiguity, not create it." Milner v. Department of Navy , 562 U.S. 562 , 574, 131 S.Ct. 1259 , 179 L.Ed.2d 268 (2011). And as we have seen, no ambiguity exists about how Title VII's terms apply to the facts before us. To be sure, the statute's application in these cases reaches "beyond the principal evil" legislators may have intended or expected to address. Oncale , 523 U.S. at 79 , 118 S.Ct. 998 . But " 'the fact that [a statute] has been applied in situations not expressly anticipated by Congress' " does not demonstrate ambiguity; instead, it simply " 'demonstrates [the] breadth' " of a legislative command. Sedima , S.P.R.L. v. Imrex Co ., 473 U.S. 479 , 499, 105 S.Ct. 3275 , 87 L.Ed.2d 346 (1985). And "it is ultimately the provisions of " those legislative commands "rather than the principal concerns of our legislators by which we are governed." Oncale , 523 U.S. at 79 , 118 S.Ct. 998 ; see also A. Scalia & B. Garner, Reading Law: The Interpretation of Legal Texts 101 (2012) (noting that unexpected applications of broad language reflect only Congress's "presumed point [to] produce general coverage-not to leave room for courts to recognize ad hoc exceptions").

 *1750 Still, while legislative history can never defeat unambiguous statutory text, historical sources can be useful for a different purpose: Because the law's ordinary meaning at the time of enactment usually governs, we must be sensitive to the possibility a statutory term that means one thing today or in one context might have meant something else at the time of its adoption or might mean something different in another context. And we must be attuned to the possibility that a statutory phrase ordinarily bears a different meaning than the terms do when viewed individually or literally. To ferret out such shifts in linguistic usage or subtle distinctions between literal and ordinary meaning, this Court has sometimes consulted the understandings of the law's drafters as some (not always conclusive) evidence. For example, in the context of the National Motor Vehicle Theft Act, this Court admitted that the term "vehicle" in 1931 could literally mean "a conveyance working on land, water or air." McBoyle v. United States , 283 U.S. 25 , 26, 51 S.Ct. 340 , 75 L.Ed. 816 (1931). But given contextual clues and "everyday speech" at the time of the Act's adoption in 1919, this Court concluded that "vehicles" in that statute included only things "moving on land," not airplanes too. Ibid . Similarly, in New Prime , we held that, while the term "contracts of employment" today might seem to encompass only contracts with employees, at the time of the statute's adoption the phrase was ordinarily understood to cover contracts with independent contractors as well. 586 U.S., at 1825 - 1826, 139 S.Ct., at 538-540 . Cf. post, at ---- - ---- (KAVANAUGH, J., dissenting) (providing additional examples).

 The employers, however, advocate nothing like that here. They do not seek to use historical sources to illustrate that the meaning of any of Title VII's language has changed since 1964 or that the statute's terms, whether viewed individually or as a whole, ordinarily carried some message we have missed. To the contrary, as we have seen, the employers agree with our understanding of all the statutory language-"discriminate against any individual ... because of such individual's ... sex." Nor do the competing dissents offer an alternative account about what these terms mean either when viewed individually or in the aggregate. Rather than suggesting that the statutory language bears some other meaning , the employers and dissents merely suggest that, because few in 1964 expected today's result , we should not dare to admit that it follows ineluctably from the statutory text. When a new application emerges that is both unexpected and important, they would seemingly have us merely point out the question, refer the subject back to Congress, and decline to enforce the plain terms of the law in the meantime.

 That is exactly the sort of reasoning this Court has long rejected. Admittedly, the employers take pains to couch their argument in terms of seeking to honor the statute's "expected applications" rather than vindicate its "legislative intent." But the concepts are closely related. One could easily contend that legislators only intended expected applications or that a statute's purpose is limited to achieving applications foreseen at the time of enactment. However framed, the employer's logic impermissibly seeks to displace the plain meaning of the law in favor of something lying beyond it.

 If anything, the employers' new framing may only add new problems. The employers assert that "no one" in 1964 or for some time after would have anticipated today's result. But is that really true? Not long after the law's passage, gay and transgender employees began filing Title VII complaints, so at least some people *1751 foresaw this potential application. See, e.g. , Smith v. Liberty Mut. Ins. Co. , 395 F.Supp. 1098 , 1099 (ND Ga. 1975) (addressing claim from 1969); Holloway v. Arthur Andersen & Co. , 566 F.2d 659 , 661 (CA9 1977) (addressing claim from 1974). And less than a decade after Title VII's passage, during debates over the Equal Rights Amendment, others counseled that its language-which was strikingly similar to Title VII's-might also protect homosexuals from discrimination. See, e.g. , Note, The Legality of Homosexual Marriage, 82 Yale L. J. 573 , 583-584 (1973).

 Why isn't that enough to demonstrate that today's result isn't totally unexpected? How many people have to foresee the application for it to qualify as "expected"? Do we look only at the moment the statute was enacted, or do we allow some time for the implications of a new statute to be worked out? Should we consider the expectations of those who had no reason to give a particular application any thought or only those with reason to think about the question? How do we account for those who change their minds over time, after learning new facts or hearing a new argument? How specifically or generally should we frame the "application" at issue? None of these questions have obvious answers, and the employers don't propose any.

 One could also reasonably fear that objections about unexpected applications will not be deployed neutrally. Often lurking just behind such objections resides a cynicism that Congress could not possibly have meant to protect a disfavored group. Take this Court's encounter with the Americans with Disabilities Act's directive that no " 'public entity' " can discriminate against any " 'qualified individual with a disability.' " Pennsylvania Dept. of Corrections v. Yeskey , 524 U.S. 206 , 208, 118 S.Ct. 1952 , 141 L.Ed.2d 215 (1998). Congress, of course, didn't list every public entity the statute would apply to. And no one batted an eye at its application to, say, post offices. But when the statute was applied to prisons , curiously, some demanded a closer look: Pennsylvania argued that "Congress did not 'envisio[n] that the ADA would be applied to state prisoners.' " Id ., at 211-212, 118 S.Ct. 1952 . This Court emphatically rejected that view, explaining that, "in the context of an unambiguous statutory text," whether a specific application was anticipated by Congress "is irrelevant." Id. , at 212, 118 S.Ct. 1952 . As Yeskey and today's cases exemplify, applying protective laws to groups that were politically unpopular at the time of the law's passage-whether prisoners in the 1990s or homosexual and transgender employees in the 1960s-often may be seen as unexpected. But to refuse enforcement just because of that, because the parties before us happened to be unpopular at the time of the law's passage, would not only require us to abandon our role as interpreters of statutes; it would tilt the scales of justice in favor of the strong or popular and neglect the promise that all persons are entitled to the benefit of the law's terms. Cf. post , at 1769 - 1773 (ALITO, J., dissenting); post, at 1833 - 1834 (KAVANAUGH, J., dissenting).

 The employer's position also proves too much. If we applied Title VII's plain text only to applications some (yet-to-be-determined) group expected in 1964, we'd have more than a little law to overturn. Start with Oncale . How many people in 1964 could have expected that the law would turn out to protect male employees? Let alone to protect them from harassment by other male employees? As we acknowledged at the time, "male-on-male sexual harassment in the workplace was assuredly not the principal evil Congress was concerned with when it enacted Title VII." 523 U.S. at 79 , 118 S.Ct. 998 . Yet the Court did not hesitate to recognize that *1752 Title VII's plain terms forbade it. Under the employer's logic, it would seem this was a mistake.

 That's just the beginning of the law we would have to unravel. As one Equal Employment Opportunity Commission (EEOC) Commissioner observed shortly after the law's passage, the words of " 'the sex provision of Title VII [are] difficult to ... control.' " Franklin, Inventing the "Traditional Concept" of Sex Discrimination, 125 Harv. L. Rev. 1307 , 1338 (2012) (quoting Federal Mediation Service To Play Role in Implementing Title VII, [1965-1968 Transfer Binder] CCH Employment Practices ¶8046, p. 6074). The "difficult[y]" may owe something to the initial proponent of the sex discrimination rule in Title VII, Representative Howard Smith. On some accounts, the congressman may have wanted (or at least was indifferent to the possibility of) broad language with wide-ranging effect. Not necessarily because he was interested in rooting out sex discrimination in all its forms, but because he may have hoped to scuttle the whole Civil Rights Act and thought that adding language covering sex discrimination would serve as a poison pill. See C. Whalen & B. Whalen, The Longest Debate: A Legislative History of the 1964 Civil Rights Act 115-118 (1985). Certainly nothing in the meager legislative history of this provision suggests it was meant to be read narrowly.

 Whatever his reasons, thanks to the broad language Representative Smith introduced, many, maybe most, applications of Title VII's sex provision were "unanticipated" at the time of the law's adoption. In fact, many now-obvious applications met with heated opposition early on, even among those tasked with enforcing the law. In the years immediately following Title VII's passage, the EEOC officially opined that listing men's positions and women's positions separately in job postings was simply helpful rather than discriminatory. Franklin, 125 Harv. L. Rev., at 1340 (citing Press Release, EEOC (Sept. 22, 1965)). Some courts held that Title VII did not prevent an employer from firing an employee for refusing his sexual advances. See, e.g. , Barnes v. Train , 1974 WL 10628 , *1 (D DC, Aug. 9, 1974). And courts held that a policy against hiring mothers but not fathers of young children wasn't discrimination because of sex. See Phillips v. Martin Marietta Corp. , 411 F.2d 1 (CA5 1969), rev'd, 400 U.S. 542 , 91 S.Ct. 496 , 27 L.Ed.2d 613 (1971) ( per curiam ).

 Over time, though, the breadth of the statutory language proved too difficult to deny. By the end of the 1960s, the EEOC reversed its stance on sex-segregated job advertising. See Franklin, 125 Harv. L. Rev., at 1345. In 1971, this Court held that treating women with children differently from men with children violated Title VII. Phillips , 400 U.S. at 544 , 91 S.Ct. 496 . And by the late 1970s, courts began to recognize that sexual harassment can sometimes amount to sex discrimination. See, e.g. , Barnes v. Costle , 561 F.2d 983 , 990 (CADC 1977). While to the modern eye each of these examples may seem "plainly [to] constitut[e] discrimination because of biological sex," post , at 1774 - 1775 (ALITO, J., dissenting), all were hotly contested for years following Title VII's enactment. And as with the discrimination we consider today, many federal judges long accepted interpretations of Title VII that excluded these situations. Cf. post , at 1833 - 1834 (KAVANAUGH, J., dissenting) (highlighting that certain lower courts have rejected Title VII claims based on homosexuality and transgender status). Would the employers have us undo every one of these unexpected applications too?

 *1753 The weighty implications of the employers' argument from expectations also reveal why they cannot hide behind the no-elephants-in-mouseholes canon. That canon recognizes that Congress "does not alter the fundamental details of a regulatory scheme in vague terms or ancillary provisions." Whitman v. American Trucking Assns. , Inc., 531 U.S. 457 , 468, 121 S.Ct. 903 , 149 L.Ed.2d 1 (2001). But it has no relevance here. We can't deny that today's holding-that employers are prohibited from firing employees on the basis of homosexuality or transgender status-is an elephant. But where's the mousehole? Title VII's prohibition of sex discrimination in employment is a major piece of federal civil rights legislation. It is written in starkly broad terms. It has repeatedly produced unexpected applications, at least in the view of those on the receiving end of them. Congress's key drafting choices-to focus on discrimination against individuals and not merely between groups and to hold employers liable whenever sex is a but-for cause of the plaintiff 's injuries-virtually guaranteed that unexpected applications would emerge over time. This elephant has never hidden in a mousehole; it has been standing before us all along.

 With that, the employers are left to abandon their concern for expected applications and fall back to the last line of defense for all failing statutory interpretation arguments: naked policy appeals. If we were to apply the statute's plain language, they complain, any number of undesirable policy consequences would follow. Cf. post , at 1778 - 1784 (ALITO, J., dissenting). Gone here is any pretense of statutory interpretation; all that's left is a suggestion we should proceed without the law's guidance to do as we think best. But that's an invitation no court should ever take up. The place to make new legislation, or address unwanted consequences of old legislation, lies in Congress. When it comes to statutory interpretation, our role is limited to applying the law's demands as faithfully as we can in the cases that come before us. As judges we possess no special expertise or authority to declare for ourselves what a self-governing people should consider just or wise. And the same judicial humility that requires us to refrain from adding to statutes requires us to refrain from diminishing them.

 What are these consequences anyway? The employers worry that our decision will sweep beyond Title VII to other federal or state laws that prohibit sex discrimination. And, under Title VII itself, they say sex-segregated bathrooms, locker rooms, and dress codes will prove unsustainable after our decision today. But none of these other laws are before us; we have not had the benefit of adversarial testing about the meaning of their terms, and we do not prejudge any such question today. Under Title VII, too, we do not purport to address bathrooms, locker rooms, or anything else of the kind. The only question before us is whether an employer who fires someone simply for being homosexual or transgender has discharged or otherwise discriminated against that individual "because of such individual's sex." As used in Title VII, the term " 'discriminate against' " refers to "distinctions or differences in treatment that injure protected individuals." Burlington N. & S.F.R. , 548 U.S. at 59 , 126 S.Ct. 2405 . Firing employees because of a statutorily protected trait surely counts. Whether other policies and practices might or might not qualify as unlawful discrimination or find justifications under other provisions of Title VII are questions for future cases, not these.

 Separately, the employers fear that complying with Title VII's requirement in cases like ours may require some employers to violate their religious convictions.

 *1754 We are also deeply concerned with preserving the promise of the free exercise of religion enshrined in our Constitution; that guarantee lies at the heart of our pluralistic society. But worries about how Title VII may intersect with religious liberties are nothing new; they even predate the statute's passage. As a result of its deliberations in adopting the law, Congress included an express statutory exception for religious organizations. § 2000e-1(a). This Court has also recognized that the First Amendment can bar the application of employment discrimination laws "to claims concerning the employment relationship between a religious institution and its ministers." Hosanna-Tabor Evangelical Lutheran Church and School v. EEOC , 565 U.S. 171 , 188, 132 S.Ct. 694 , 181 L.Ed.2d 650 (2012). And Congress has gone a step further yet in the Religious Freedom Restoration Act of 1993 (RFRA), 107 Stat. 1488 , codified at 42 U.S.C. § 2000bb et seq. That statute prohibits the federal government from substantially burdening a person's exercise of religion unless it demonstrates that doing so both furthers a compelling governmental interest and represents the least restrictive means of furthering that interest. § 2000bb-1. Because RFRA operates as a kind of super statute, displacing the normal operation of other federal laws, it might supersede Title VII's commands in appropriate cases. See § 2000bb-3.

 But how these doctrines protecting religious liberty interact with Title VII are questions for future cases too. Harris Funeral Homes did unsuccessfully pursue a RFRA-based defense in the proceedings below. In its certiorari petition, however, the company declined to seek review of that adverse decision, and no other religious liberty claim is now before us. So while other employers in other cases may raise free exercise arguments that merit careful consideration, none of the employers before us today represent in this Court that compliance with Title VII will infringe their own religious liberties in any way.

 *

 Some of those who supported adding language to Title VII to ban sex discrimination may have hoped it would derail the entire Civil Rights Act. Yet, contrary to those intentions, the bill became law. Since then, Title VII's effects have unfolded with far-reaching consequences, some likely beyond what many in Congress or elsewhere expected.

 But none of this helps decide today's cases. Ours is a society of written laws. Judges are not free to overlook plain statutory commands on the strength of nothing more than suppositions about intentions or guesswork about expectations. In Title VII, Congress adopted broad language making it illegal for an employer to rely on an employee's sex when deciding to fire that employee. We do not hesitate to recognize today a necessary consequence of that legislative choice: An employer who fires an individual merely for being gay or transgender defies the law.

 The judgments of the Second and Sixth Circuits in Nos. 17-1623 and 18-107 are affirmed. The judgment of the Eleventh Circuit in No. 17-1618 is reversed, and the case is remanded for further proceedings consistent with this opinion.

 It is so ordered.

 Justice ALITO, with whom Justice THOMAS joins, dissenting.

 There is only one word for what the Court has done today: legislation. The document that the Court releases is in the form of a judicial opinion interpreting a statute, but that is deceptive.

 Title VII of the Civil Rights Act of 1964 prohibits employment discrimination on *1755 any of five specified grounds: "race, color, religion, sex, [and] national origin." 42 U.S.C. § 2000e-2(a)(1). Neither "sexual orientation" nor "gender identity" appears on that list. For the past 45 years, bills have been introduced in Congress to add "sexual orientation" to the list, 1 and in recent years, bills have included "gender identity" as well. 2 But to date, none has passed both Houses.

 Last year, the House of Representatives passed a bill that would amend Title VII by defining sex discrimination to include both "sexual orientation" and "gender identity," H.R. 5, 116th Cong., 1st Sess. (2019), but the bill has stalled in the Senate. An alternative bill, H.R. 5331, 116th Cong., 1st Sess. (2019), would add similar prohibitions but contains provisions to protect religious liberty. 3 This bill remains before a House Subcommittee.

 Because no such amendment of Title VII has been enacted in accordance with the requirements in the Constitution (passage in both Houses and presentment to the President, Art. I, § 7, cl. 2), Title VII's prohibition of discrimination because of "sex" still means what it has always meant. But the Court is not deterred by these constitutional niceties. Usurping the constitutional authority of the other branches, the Court has essentially taken H.R. 5's provision on employment discrimination and issued it under the guise of statutory interpretation. 4 A more brazen abuse of our authority to interpret statutes is hard to recall.

 The Court tries to convince readers that it is merely enforcing the terms of the statute, but that is preposterous. Even as understood today, the concept of discrimination because of "sex" is different from discrimination because of "sexual orientation" or "gender identity." And in any event, our duty is to interpret statutory terms to "mean what they conveyed to reasonable people at the time they were written ." A. Scalia & B. Garner, Reading Law: The Interpretation of Legal Texts 16 (2012) (emphasis added). If every single living American had been surveyed in 1964, it would have been hard to find any who thought that discrimination because of sex meant discrimination because of sexual orientation--not to mention gender identity, a concept that was essentially unknown at the time.

 The Court attempts to pass off its decision as the inevitable product of the textualist school of statutory interpretation championed by our late colleague Justice Scalia, but no one should be fooled. The Court's opinion is like a pirate ship. It sails under a textualist flag, but what it actually *1756 represents is a theory of statutory interpretation that Justice Scalia excoriated--the theory that courts should "update" old statutes so that they better reflect the current values of society. See A. Scalia, A Matter of Interpretation 22

 (1997). If the Court finds it appropriate to adopt this theory, it should own up to what it is doing. 5

 Many will applaud today's decision because they agree on policy grounds with the Court's updating of Title VII. But the question in these cases is not whether discrimination because of sexual orientation or gender identity should be outlawed. The question is whether Congress did that in 1964 .

 It indisputably did not.

 I

 A

 Title VII, as noted, prohibits discrimination "because of ... sex," § 2000e-2(a)(1), and in 1964, it was as clear as clear could be that this meant discrimination because of the genetic and anatomical characteristics that men and women have at the time of birth. Determined searching has not found a single dictionary from that time that defined "sex" to mean sexual orientation, gender identity, or "transgender status." 6 Ante , at 1737. (Appendix A, infra , to this opinion includes the full definitions of "sex" in the unabridged dictionaries in use in the 1960s.)

 In all those dictionaries, the primary definition of "sex" was essentially the same as that in the then-most recent edition of Webster's New International Dictionary 2296 (def. 1) (2d ed. 1953): "[o]ne of the two divisions of organisms formed on the distinction of male and female." See also American Heritage Dictionary 1187 (def. 1(a)) (1969) ("The property or quality by which organisms are classified according to their reproductive functions"); Random House Dictionary of the English Language 1307 (def. 1) (1966) (Random House Dictionary) ("the fact or character of being either male or female"); 9 Oxford English Dictionary 577 (def. 1) (1933) ("Either of the two divisions of organic beings distinguished as male and female respectively").

 The Court does not dispute that this is what "sex" means in Title VII, although it coyly suggests that there is at least some support for a different and potentially relevant definition. Ante , at 1739. (I address alternative definitions below. See Part I-B-3, infra .) But the Court declines to stand on that ground and instead "proceed[s] on the assumption that 'sex' ...

 *1757 refer[s] only to biological distinctions between male and female." Ante , at 1739.

 If that is so, it should be perfectly clear that Title VII does not reach discrimination because of sexual orientation or gender identity. If "sex" in Title VII means biologically male or female, then discrimination because of sex means discrimination because the person in question is biologically male or biologically female, not because that person is sexually attracted to members of the same sex or identifies as a member of a particular gender.

 How then does the Court claim to avoid that conclusion? The Court tries to cloud the issue by spending many pages discussing matters that are beside the point. The Court observes that a Title VII plaintiff need not show that "sex" was the sole or primary motive for a challenged employment decision or its sole or primary cause; that Title VII is limited to discrimination with respect to a list of specified actions (such as hiring, firing, etc.); and that Title VII protects individual rights, not group rights. See ante , at 1739 - 1741, 1742.

 All that is true, but so what? In cases like those before us, a plaintiff must show that sex was a "motivating factor" in the challenged employment action, 42 U.S.C. § 2000e-2(m), so the question we must decide comes down to this: if an individual employee or applicant for employment shows that his or her sexual orientation or gender identity was a "motivating factor" in a hiring or discharge decision, for example, is that enough to establish that the employer discriminated "because of ... sex"? Or, to put the same question in different terms, if an employer takes an employment action solely because of the sexual orientation or gender identity of an employee or applicant, has that employer necessarily discriminated because of biological sex?

 The answers to those questions must be no, unless discrimination because of sexual orientation or gender identity inherently constitutes discrimination because of sex. The Court attempts to prove that point, and it argues, not merely that the terms of Title VII can be interpreted that way but that they cannot reasonably be interpreted any other way . According to the Court, the text is unambiguous. See ante , at 1749 - 1750, 1751, 1752 - 1753.

 The arrogance of this argument is breathtaking. As I will show, there is not a shred of evidence that any Member of Congress interpreted the statutory text that way when Title VII was enacted. See Part III-B, infra . But the Court apparently thinks that this was because the Members were not "smart enough to realize" what its language means. Hively v. Ivy Tech Community College of Ind. , 853 F.3d 339 , 357 (CA7 2017) (Posner, J., concurring). The Court seemingly has the same opinion about our colleagues on the Courts of Appeals, because until 2017, every single Court of Appeals to consider the question interpreted Title VII's prohibition against sex discrimination to mean discrimination on the basis of biological sex. See Part III-C, infra . And for good measure, the Court's conclusion that Title VII unambiguously reaches discrimination on the basis of sexual orientation and gender identity necessarily means that the EEOC failed to see the obvious for the first 48 years after Title VII became law. 7 Day in *1758 and day out, the Commission enforced Title VII but did not grasp what discrimination "because of ... sex" unambiguously means. See Part III-C, infra .

 The Court's argument is not only arrogant, it is wrong. It fails on its own terms. "Sex," "sexual orientation," and "gender identity" are different concepts, as the Court concedes. Ante , at 1746 - 1747 ("homosexuality and transgender status are distinct concepts from sex"). And neither "sexual orientation" nor "gender identity" is tied to either of the two biological sexes. See ante , at 1742 (recognizing that "discrimination on these bases" does not have "some disparate impact on one sex or another"). Both men and women may be attracted to members of the opposite sex, members of the same sex, or members of both sexes. 8 And individuals who are born with the genes and organs of either biological sex may identify with a different gender. 9

 Using slightly different terms, the Court asserts again and again that discrimination because of sexual orientation or gender identity inherently or necessarily entails discrimination because of sex. See ante , at 1737 (When an employer "fires an individual for being homosexual or transgender," "[s]ex plays a necessary and undisguisable role in the decision"); ante , at 1741 ("[I]t is impossible to discriminate against a person for being homosexual or transgender without discriminating against that individual based on sex"); ante , at 1742 ("[W]hen an employer discriminates against homosexual or transgender employees, [the] employer ... inescapably intends to rely on sex in its decisionmaking"); ante , at 1743 ("For an employer to discriminate against employees for being homosexual or transgender, the employer must intentionally discriminate against individual men and women in part because of sex"); ante , at 1744 ("When an employer fires an employee for being homosexual or transgender, it necessarily and intentionally discriminates against that individual in part because of sex"); ante , at 1747 ("[D]iscrimination based on homosexuality or transgender status necessarily entails discrimination based on sex"). But repetition of an assertion does not make it so, and the Court's repeated assertion is demonstrably untrue.

 Contrary to the Court's contention, discrimination because of sexual orientation or gender identity does not in and of itself entail discrimination because of sex. We can see this because it is quite possible for an employer to discriminate on those grounds without taking the sex of an individual applicant or employee into account. An employer can have a policy that says: "We do not hire gays, lesbians, or transgender individuals." And an employer can implement this policy without paying any attention to or even knowing the biological sex of gay, lesbian, and transgender applicants. In fact, at the time of the enactment of Title VII, the United States military had a blanket policy of refusing to enlist gays *1759 or lesbians, and under this policy for years thereafter, applicants for enlistment were required to complete a form that asked whether they were "homosexual." Appendix D, infra , at 1803, 1816.

 At oral argument, the attorney representing the employees, a prominent professor of constitutional law, was asked if there would be discrimination because of sex if an employer with a blanket policy against hiring gays, lesbians, and transgender individuals implemented that policy without knowing the biological sex of any job applicants. Her candid answer was that this would "not" be sex discrimination. 10 And she was right.

 The attorney's concession was necessary, but it is fatal to the Court's interpretation, for if an employer discriminates against individual applicants or employees without even knowing whether they are male or female, it is impossible to argue that the employer intentionally discriminated because of sex. Contra, ante , at 1746 - 1747. An employer cannot intentionally discriminate on the basis of a characteristic of which the employer has no knowledge. And if an employer does not violate Title VII by discriminating on the basis of sexual orientation or gender identity without knowing the sex of the affected individuals, there is no reason why the same employer could not lawfully implement the same policy even if it knows the sex of these individuals. If an employer takes an adverse employment action for a perfectly legitimate reason-for example, because an employee stole company property-that action is not converted into sex discrimination simply because the employer knows the employee's sex. As explained, a disparate treatment case requires proof of intent- i.e., that the employee's sex motivated the firing. In short, what this example shows is that discrimination because of sexual orientation or gender identity does not inherently or necessarily entail discrimination because of sex, and for that reason, the Court's chief argument collapses.

 Trying to escape the consequences of the attorney's concession, the Court offers its own hypothetical:

 "Suppose an employer's application form offered a single box to check if the applicant is either black or Catholic. If the employer refuses to hire anyone who checks that box, would we conclude the employer has complied with Title VII, so long as it studiously avoids learning any particular applicant's race or religion? Of course not." Ante , at 1746.
 How this hypothetical proves the Court's point is a mystery. A person who checked that box would presumably be black, Catholic, or both, and refusing to hire an applicant because of race or religion is prohibited by Title VII. Rejecting applicants who checked a box indicating that they are homosexual is entirely different because it is impossible to tell from that answer whether an applicant is male or female.

 The Court follows this strange hypothetical with an even stranger argument. The Court argues that an applicant could not answer the question whether he or she is homosexual without knowing something about sex. If the applicant was unfamiliar with the term "homosexual," the applicant would have to look it up or ask what the term means. And because this applicant would have to take into account his or her sex and that of the persons to whom he or *1760 she is sexually attracted to answer the question, it follows, the Court reasons, that an employer could not reject this applicant without taking the applicant's sex into account. See ante , at 1746 - 1747.

 This is illogical. Just because an applicant cannot say whether he or she is homosexual without knowing his or her own sex and that of the persons to whom the applicant is attracted, it does not follow that an employer cannot reject an applicant based on homosexuality without knowing the applicant's sex.

 While the Court's imagined application form proves nothing, another hypothetical case offered by the Court is telling. But what it proves is not what the Court thinks. The Court posits:

 "Imagine an employer who has a policy of firing any employee known to be homosexual. The employer hosts an office holiday party and invites employees to bring their spouses. A model employee arrives and introduces a manager to Susan, the employee's wife. Will that employee be fired? If the policy works as the employer intends, the answer depends entirely on whether the model employee is a man or a woman." Ante , at 1742.
 This example disproves the Court's argument because it is perfectly clear that the employer's motivation in firing the female employee had nothing to do with that employee's sex. The employer presumably knew that this employee was a woman before she was invited to the fateful party. Yet the employer, far from holding her biological sex against her, rated her a "model employee." At the party, the employer learned something new, her sexual orientation, and it was this new information that motivated her discharge. So this is another example showing that discrimination because of sexual orientation does not inherently involve discrimination because of sex.

 In addition to the failed argument just discussed, the Court makes two other arguments, more or less in passing. The first of these is essentially that sexual orientation and gender identity are closely related to sex. The Court argues that sexual orientation and gender identity are "inextricably bound up with sex," ante , at 1742, and that discrimination on the basis of sexual orientation or gender identity involves the application of "sex-based rules," ante , at 1745 - 1746. This is a variant of an argument found in many of the briefs filed in support of the employees and in the lower court decisions that agreed with the Court's interpretation. All these variants stress that sex, sexual orientation, and gender identity are related concepts. The Seventh Circuit observed that "[i]t would require considerable calisthenics to remove 'sex' from 'sexual orientation.' " Hively , 853 F.3d at 350 . 11 The Second Circuit wrote that sex is necessarily "a factor in sexual orientation" and further concluded that "sexual orientation is a function of sex." 883 F.3d 100 , 112-113 (CA2 2018) (en banc). Bostock's brief and those of amici supporting his position contend that sexual orientation is "a sex-based consideration." 12 Other briefs state that sexual orientation is "a function of sex" 13 or is *1761 "intrinsically related to sex." 14 Similarly, Stephens argues that sex and gender identity are necessarily intertwined: "By definition, a transgender person is someone who lives and identifies with a sex different than the sex assigned to the person at birth." 15

 It is curious to see this argument in an opinion that purports to apply the purest and highest form of textualism because the argument effectively amends the statutory text. Title VII prohibits discrimination because of sex itself, not everything that is related to, based on, or defined with reference to, "sex." Many things are related to sex. Think of all the nouns other than "orientation" that are commonly modified by the adjective "sexual." Some examples yielded by a quick computer search are "sexual harassment," "sexual assault," "sexual violence," "sexual intercourse," and "sexual content."

 Does the Court really think that Title VII prohibits discrimination on all these grounds? Is it unlawful for an employer to refuse to hire an employee with a record of sexual harassment in prior jobs? Or a record of sexual assault or violence?

 To be fair, the Court does not claim that Title VII prohibits discrimination because of everything that is related to sex. The Court draws a distinction between things that are "inextricably" related and those that are related in "some vague sense." Ante , at 1741 - 1742. Apparently the Court would graft onto Title VII some arbitrary line separating the things that are related closely enough and those that are not. 16 And it would do this in the name of high textualism. An additional argument made in passing also fights the text of Title VII and the policy it reflects. The Court proclaims that "[a]n individual's homosexuality or transgender status is not relevant to employment decisions." Ante , at 1741. That is the policy view of many people in 2020, and perhaps Congress would have amended Title VII to implement it if this Court had not intervened. But that is not the policy embodied in Title VII in its current form. Title VII prohibits discrimination based on five specified grounds, and neither sexual orientation nor gender identity is on the list. As long as an employer does not discriminate based on one of the listed grounds, the employer is free to decide for itself which characteristics are "relevant to [its] employment decisions." Ibid. By proclaiming that sexual orientation and gender identity are "not relevant to employment decisions," the Court updates Title VII to reflect what it regards as 2020 values.

 The Court's remaining argument is based on a hypothetical that the Court finds instructive. In this hypothetical, an employer has two employees who are "attracted to men," and " to the employer's mind " the two employees are "materially identical" except that one is a man and the other is a woman. Ante , at 1741 (emphasis added). The Court reasons that if the employer fires the man but not the woman, the employer is necessarily motivated by the man's biological sex. Ante , at 1741 - 1742. After all, if two employees are identical in every respect but sex, and the employer *1762 fires only one, what other reason could there be?

 The problem with this argument is that the Court loads the dice. That is so because in the mind of an employer who does not want to employ individuals who are attracted to members of the same sex, these two employees are not materially identical in every respect but sex. On the contrary, they differ in another way that the employer thinks is quite material. And until Title VII is amended to add sexual orientation as a prohibited ground, this is a view that an employer is permitted to implement. As noted, other than prohibiting discrimination on any of five specified grounds, "race, color, religion, sex, [and] national origin." 42 U.S.C. § 2000e-2(a)(1), Title VII allows employers to decide whether two employees are "materially identical." Even idiosyncratic criteria are permitted; if an employer thinks that Scorpios make bad employees, the employer can refuse to hire Scorpios. Such a policy would be unfair and foolish, but under Title VII, it is permitted. And until Title VII is amended, so is a policy against employing gays, lesbians, or transgender individuals.

 Once this is recognized, what we have in the Court's hypothetical case are two employees who differ in two ways--sex and sexual orientation--and if the employer fires one and keeps the other, all that can be inferred is that the employer was motivated either entirely by sexual orientation, entirely by sex, or in part by both. We cannot infer with any certainty, as the hypothetical is apparently meant to suggest, that the employer was motivated even in part by sex. The Court harps on the fact that under Title VII a prohibited ground need not be the sole motivation for an adverse employment action, see ante , at 1741 - 1742, 1743 - 1745, 1747 - 1748, but its example does not show that sex necessarily played any part in the employer's thinking.

 The Court tries to avoid this inescapable conclusion by arguing that sex is really the only difference between the two employees. This is so, the Court maintains, because both employees "are attracted to men." Ante , at 1741 - 1742. Of course, the employer would couch its objection to the man differently. It would say that its objection was his sexual orientation. So this may appear to leave us with a battle of labels. If the employer's objection to the male employee is characterized as attraction to men, it seems that he is just like the woman in all respects except sex and that the employer's disparate treatment must be based on that one difference. On the other hand, if the employer's objection is sexual orientation or homosexuality, the two employees differ in two respects, and it cannot be inferred that the disparate treatment was due even in part to sex.

 The Court insists that its label is the right one, and that presumably is why it makes such a point of arguing that an employer cannot escape liability under Title VII by giving sex discrimination some other name. See ante , at 1743 - 1744, 1745 - 1746. That is certainly true, but so is the opposite. Something that is not sex discrimination cannot be converted into sex discrimination by slapping on that label. So the Court cannot prove its point simply by labeling the employer's objection as "attract[ion] to men." Ante , at 1741 - 1742. Rather, the Court needs to show that its label is the correct one.

 And a labeling standoff would not help the Court because that would mean that the bare text of Title VII does not unambiguously show that its interpretation is right. The Court would have no justification for its stubborn refusal to look any further.

 *1763 As it turns out, however, there is no standoff. It can easily be shown that the employer's real objection is not "attract[ion] to men" but homosexual orientation.

 In an effort to prove its point, the Court carefully includes in its example just two employees, a homosexual man and a heterosexual woman, but suppose we add two more individuals, a woman who is attracted to women and a man who is attracted to women. (A large employer will likely have applicants and employees who fall into all four categories, and a small employer can potentially have all four as well.) We now have the four exemplars listed below, with the discharged employees crossed out:

 Man attracted to men
 Woman attracted to men
 Woman attracted to women
 Man attracted to women
 The discharged employees have one thing in common. It is not biological sex, attraction to men, or attraction to women. It is attraction to members of their own sex-in a word, sexual orientation. And that, we can infer, is the employer's real motive.

 In sum, the Court's textual arguments fail on their own terms. The Court tries to prove that "it is impossible to discriminate against a person for being homosexual or transgender without discriminating against that individual based on sex," ante, at 1741, but as has been shown, it is entirely possible for an employer to do just that. "[H]omosexuality and transgender status are distinct concepts from sex," ante , at 1746 - 1747, and discrimination because of sexual orientation or transgender status does not inherently or necessarily constitute discrimination because of sex. The Court's arguments are squarely contrary to the statutory text.

 But even if the words of Title VII did not definitively refute the Court's interpretation, that would not justify the Court's refusal to consider alternative interpretations. The Court's excuse for ignoring everything other than the bare statutory text is that the text is unambiguous and therefore no one can reasonably interpret the text in any way other than the Court does. Unless the Court has met that high standard, it has no justification for its blinkered approach. And to say that the Court's interpretation is the only possible reading is indefensible.

 B

 Although the Court relies solely on the arguments discussed above, several other arguments figure prominently in the decisions of the lower courts and in briefs submitted by or in support of the employees. The Court apparently finds these arguments unpersuasive, and so do I, but for the sake of completeness, I will address them briefly.

 1

 One argument, which relies on our decision in Price Waterhouse v. Hopkins , 490 U.S. 228 , 109 S.Ct. 1775 , 104 L.Ed.2d 268 (1989) (plurality opinion), is that discrimination because of sexual orientation or gender identity violates Title VII because it constitutes prohibited discrimination on the basis of sex stereotypes. See 883 F.3d at 119-123 ; Hively , 853 F.3d at 346 ; 884 F.3d 560 , 576-577 (CA6 2018). The argument goes like this. Title VII prohibits discrimination based on stereotypes about the way men and women should behave; the belief that a person should be attracted only to persons of the opposite sex and the belief that a person should identify with his or her biological sex are examples of such stereotypes; therefore, discrimination on either of these grounds is unlawful.

 *1764 This argument fails because it is based on a faulty premise, namely, that Title VII forbids discrimination based on sex stereotypes. It does not. It prohibits discrimination because of "sex," and the two concepts are not the same. See Price Waterhouse , 490 U.S. at 251 , 109 S.Ct. 1775 . That does not mean, however, that an employee or applicant for employment cannot prevail by showing that a challenged decision was based on a sex stereotype. Such evidence is relevant to prove discrimination because of sex, and it may be convincing where the trait that is inconsistent with the stereotype is one that would be tolerated and perhaps even valued in a person of the opposite sex. See ibid.

 Much of the plaintiff 's evidence in Price Waterhouse was of this nature. The plaintiff was a woman who was passed over for partnership at an accounting firm, and some of the adverse comments about her work appeared to criticize her for being forceful and insufficiently "feminin[e]." Id. , at 235-236, 109 S.Ct. 1775 .

 The main issue in Price Waterhouse --the proper allocation of the burdens of proof in a so-called mixed motives Title VII case-is not relevant here, but the plurality opinion, endorsed by four Justices, commented on the issue of sex stereotypes. The plurality observed that "sex stereotypes do not inevitably prove that gender played a part in a particular employment decision" but "can certainly be evidence that gender played a part." Id. , at 251, 109 S.Ct. 1775 . 17 And the plurality made it clear that "[t]he plaintiff must show that the employer actually relied on her gender in making its decision." Ibid.

 Plaintiffs who allege that they were treated unfavorably because of their sexual orientation or gender identity are not in the same position as the plaintiff in Price Waterhouse . In cases involving discrimination based on sexual orientation or gender identity, the grounds for the employer's decision-that individuals should be sexually attracted only to persons of the opposite biological sex or should identify with their biological sex-apply equally to men and women. "[H]eterosexuality is not a female stereotype; it not a male stereotype; it is not a sexspecific stereotype at all." Hively , 853 F.3d at 370 (Sykes, J., dissenting).

 To be sure, there may be cases in which a gay, lesbian, or transgender individual can make a claim like the one in Price Waterhouse . That is, there may be cases where traits or behaviors that some people associate with gays, lesbians, or transgender individuals are tolerated or valued in persons of one biological sex but not the other. But that is a different matter.

 2

 A second prominent argument made in support of the result that the Court now reaches analogizes discrimination against gays and lesbians to discrimination against a person who is married to or has an intimate relationship with a person of a different race. Several lower court cases have held that discrimination on this ground violates Title VII. See, e.g. , Holcomb v. Iona College , 521 F.3d 130 (CA2 2008) ; Parr v. Woodmen of World Life Ins. Co. , 791 F.2d 888 (CA11 1986). And the *1765 logic of these decisions, it is argued, applies equally where an employee or applicant is treated unfavorably because he or she is married to, or has an intimate relationship with, a person of the same sex.

 This argument totally ignores the historically rooted reason why discrimination on the basis of an interracial relationship constitutes race discrimination. And without taking history into account, it is not easy to see how the decisions in question fit the terms of Title VII.

 Recall that Title VII makes it unlawful for an employer to discriminate against an individual "because of such individual's race ." 42 U.S.C. § 2000e-2(a) (emphasis added). So if an employer is happy to employ whites and blacks but will not employ any employee in an interracial relationship, how can it be said that the employer is discriminating against either whites or blacks "because of such individual's race"? This employer would be applying the same rule to all its employees regardless of their race.

 The answer is that this employer is discriminating on a ground that history tells us is a core form of race discrimination. 18 "It would require absolute blindness to the history of racial discrimination in this country not to understand what is at stake in such cases .... A prohibition on 'race-mixing' was ... grounded in bigotry against a particular race and was an integral part of preserving the rigid hierarchical distinction that denominated members of the black race as inferior to whites." 883 F.3d at 158-159 (Lynch, J., dissenting).

 Discrimination because of sexual orientation is different. It cannot be regarded as a form of sex discrimination on the ground that applies in race cases since discrimination because of sexual orientation is not historically tied to a project that aims to subjugate either men or women. An employer who discriminates on this ground might be called "homophobic" or "transphobic," but not sexist. See Wittmer v. Phillips 66 Co. , 915 F.3d 328 , 338 (CA5 2019) (Ho, J., concurring).

 The opinion of the Court intimates that the term "sex" was not universally understood in 1964 to refer just to the categories of male and female, see ante , at 1739, and while the Court does not take up any alternative definition as a ground for its decision, I will say a word on this subject.

 As previously noted, the definitions of "sex" in the unabridged dictionaries in use in the 1960s are reproduced in Appendix A, infra . Anyone who examines those definitions can see that the primary definition in every one of them refers to the division of living things into two groups, male and female, based on biology, and most of the definitions further down the list are the same or very similar. In addition, some definitions refer to heterosexual sex acts. See Random House Dictionary 1307 ("coitus," "sexual intercourse" (defs. 5-6)); American Heritage Dictionary, at 1187 ("sexual intercourse" (def. 5)). 19

 *1766 Aside from these, what is there? One definition, "to neck passionately," Random House Dictionary 1307 (def. 8), refers to sexual conduct that is not necessarily heterosexual. But can it be seriously argued that one of the aims of Title VII is to outlaw employment discrimination against employees, whether heterosexual or homosexual, who engage in necking? And even if Title VII had that effect, that is not what is at issue in cases like those before us.

 That brings us to the two remaining subsidiary definitions, both of which refer to sexual urges or instincts and their manifestations. See the fourth definition in the American Heritage Dictionary, at 1187 ("the sexual urge or instinct as it manifests itself in behavior"), and the fourth definition in both Webster's Second and Third ("[p]henomena of sexual instincts and their manifestations," Webster's New International Dictionary, at 2296 (2d ed.); Webster's Third New International Dictionary 2081 (1966)). Since both of these come after three prior definitions that refer to men and women, they are most naturally read to have the same association, and in any event, is it plausible that Title VII prohibits discrimination based on any sexual urge or instinct and its manifestations? The urge to rape?

 Viewing all these definitions, the overwhelming impact is that discrimination because of "sex" was understood during the era when Title VII was enacted to refer to men and women. (The same is true of current definitions, which are reproduced in Appendix B, infra .) This no doubt explains why neither this Court nor any of the lower courts have tried to make much of the dictionary definitions of sex just discussed.

 II

 A

 So far, I have not looked beyond dictionary definitions of "sex," but textualists like Justice Scalia do not confine their inquiry to the scrutiny of dictionaries. See Manning, Textualism and the Equity of the Statute, 101 Colum. L. Rev. 1 , 109 (2001). Dictionary definitions are valuable because they are evidence of what people at the time of a statute's enactment would have understood its words to mean. Ibid. But they are not the only source of relevant evidence, and what matters in the end is the answer to the question that the evidence is gathered to resolve: How would the terms of a statute have been understood by ordinary people at the time of enactment?

 Justice Scalia was perfectly clear on this point. The words of a law, he insisted, "mean what they conveyed to reasonable people at the time. " Reading Law, at 16 (emphasis added). 20

 Leading proponents of Justice Scalia's school of textualism have expounded on this principle and explained that it is grounded on an understanding of the way language works. As Dean John F. Manning explains, "the meaning of language depends on the way a linguistic community uses words and phrases in context." What Divides Textualists From Purposivists? 106 Colum. L. Rev. 70 , 78 (2006). "[O]ne can make sense of others' communications only by placing them in their appropriate social and linguistic context," id ., at 79-80, and this is no less true of statutes than any other verbal communications. "[S]tatutes convey meaning only because members of a relevant linguistic community apply shared background conventions for understanding *1767 how particular words are used in particular contexts." Manning, The Absurdity Doctrine, 116 Harv. L. Rev. 2387 , 2457 (2003). Therefore, judges should ascribe to the words of a statute "what a reasonable person conversant with applicable social conventions would have understood them to be adopting." Manning, 106 Colum. L. Rev., at 77. Or, to put the point in slightly different terms, a judge interpreting a statute should ask " 'what one would ordinarily be understood as saying, given the circumstances in which one said it.' " Manning, 116 Harv. L. Rev., at 2397-2398.

 Judge Frank Easterbrook has made the same points:

 "Words are arbitrary signs, having meaning only to the extent writers and readers share an understanding.... Language in general, and legislation in particular, is a social enterprise to which both speakers and listeners contribute, drawing on background understandings and the structure and circumstances of the utterance." Herrmann v. Cencom Cable Assocs., Inc. , 978 F.2d 978 , 982 (CA7 1992).
 Consequently, "[s]licing a statute into phrases while ignoring ... the setting of the enactment ... is a formula for disaster." Ibid . ; see also Continental Can Co. v. Chicago Truck Drivers, Helpers and Warehouse Workers Union (Independent) Pension Fund , 916 F.2d 1154 , 1157 (CA7 1990) ("You don't have to be Ludwig Wittgenstein or Hans-Georg Gadamer to know that successful communication depends on meanings shared by interpretive communities").

 Thus, when textualism is properly understood, it calls for an examination of the social context in which a statute was enacted because this may have an important bearing on what its words were understood to mean at the time of enactment. Textualists do not read statutes as if they were messages picked up by a powerful radio telescope from a distant and utterly unknown civilization. Statutes consist of communications between members of a particular linguistic community, one that existed in a particular place and at a particular time, and these communications must therefore be interpreted as they were understood by that community at that time.

 For this reason, it is imperative to consider how Americans in 1964 would have understood Title VII's prohibition of discrimination because of sex. To get a picture of this, we may imagine this scene. Suppose that, while Title VII was under consideration in Congress, a group of average Americans decided to read the text of the bill with the aim of writing or calling their representatives in Congress and conveying their approval or disapproval. What would these ordinary citizens have taken "discrimination because of sex" to mean? Would they have thought that this language prohibited discrimination because of sexual orientation or gender identity?

 B

 The answer could not be clearer. In 1964, ordinary Americans reading the text of Title VII would not have dreamed that discrimination because of sex meant discrimination because of sexual orientation, much less gender identity. The ordinary meaning of discrimination because of "sex" was discrimination because of a person's biological sex, not sexual orientation or gender identity. The possibility that discrimination on either of these grounds might fit within some exotic understanding of sex discrimination would not have crossed their minds.

 1

 In 1964, the concept of prohibiting discrimination "because of sex" was no novelty.

 *1768 It was a familiar and well-understood concept, and what it meant was equal treatment for men and women.

 Long before Title VII was adopted, many pioneering state and federal laws had used language substantively indistinguishable from Title VII's critical phrase, "discrimination because of sex." For example, the California Constitution of 1879 stipulated that no one, " on account of sex , [could] be disqualified from entering upon or pursuing any lawful business, vocation, or profession." Art. XX, § 18 (emphasis added). It also prohibited a student's exclusion from any state university department "on account of sex." Art. IX, § 9; accord, Mont. Const., Art. XI, § 9 (1889).

 Wyoming's first Constitution proclaimed broadly that "[b]oth male and female citizens of this state shall equally enjoy all civil, political and religious rights and privileges," Art. VI, § 1 (1890), and then provided specifically that "[i]n none of the public schools ... shall distinction or discrimination be made on account of sex ," Art. VII, § 10 (emphasis added); see also § 16 (the "university shall be equally open to students of both sexes"). Washington's Constitution likewise required "ample provision for the education of all children ... without distinction or preference on account of ... sex ." Art. IX, § 1 (1889) (emphasis added).

 The Constitution of Utah, adopted in 1895, provided that the right to vote and hold public office "shall not be denied or abridged on account of sex ." Art. IV, § 1 (emphasis added). And in the next sentence it made clear what "on account of sex" meant, stating that "[b]oth male and female citizens ... shall enjoy equally all civil, political and religious rights and privileges." Ibid .

 The most prominent example of a provision using this language was the Nineteenth Amendment, ratified in 1920, which bans the denial or abridgment of the right to vote "on account of sex." U.S. Const., Amdt. 19. Similar language appeared in the proposal of the National Woman's Party for an Equal Rights Amendment. As framed in 1921, this proposal forbade all "political, civil or legal disabilities or inequalities on account of sex , [o]r on account of marriage." Women Lawyers Meet: Representatives of 20 States Endorse Proposed Equal Rights Amendment, N. Y. Times, Sept. 16, 1921, p. 10.

 Similar terms were used in the precursor to the Equal Pay Act. Introduced in 1944 by Congresswoman Winifred C. Stanley, it proclaimed that "[d]iscrimination against employees, in rates of compensation paid, on account of sex " was "contrary to the public interest." H.R. 5056, 78th Cong., 2d Sess.

 In 1952, the new Constitution for Puerto Rico, which was approved by Congress, 66 Stat. 327 , prohibited all "discrimination ... on account of ... sex ," Art. II, Bill of Rights § 1 (emphasis added), and in the landmark Immigration and Nationality Act of 1952, Congress outlawed discrimination in naturalization " because of ... sex ." 8 U.S.C. § 1422 (emphasis added).

 In 1958, the International Labour Organisation, a United Nations agency of which the United States is a member, recommended that nations bar employment discrimination "made on the basis of ... sex ." Convention (No. 111) Concerning Discrimination in Respect of Employment and Occupation, Art. 1(a), June 25, 1958, 362 U. N. T. S. 32 (emphasis added).

 In 1961, President Kennedy ordered the Civil Service Commission to review and modify personnel policies "to assure that selection for any career position is hereinafter made solely on the basis of individual *1769 merit and fitness, without regard to sex ." 21 He concurrently established a "Commission on the Status of Women" and directed it to recommend policies "for overcoming discriminations in government and private employment on the basis of sex ." Exec. Order No. 10980, 3 CFR 138 (1961 Supp.) (emphasis added).

 In short, the concept of discrimination "because of," "on account of," or "on the basis of " sex was well understood. It was part of the campaign for equality that had been waged by women's rights advocates for more than a century, and what it meant was equal treatment for men and women. 22

 2

 Discrimination "because of sex" was not understood as having anything to do with discrimination because of sexual orientation or transgender status. Any such notion would have clashed in spectacular fashion with the societal norms of the day.

 For most 21st-century Americans, it is painful to be reminded of the way our society once treated gays and lesbians, but any honest effort to understand what the terms of Title VII were understood to mean when enacted must take into account the societal norms of that time. And the plain truth is that in 1964 homosexuality was thought to be a mental disorder, and homosexual conduct was regarded as morally culpable and worthy of punishment.

 In its then-most recent Diagnostic and Statistical Manual of Mental Disorders (1952) (DSM-I), the American Psychiatric Association (APA) classified same-sex attraction as a "sexual deviation," a particular type of "sociopathic personality disturbance," id. , at 38-39, and the next edition, issued in 1968, similarly classified homosexuality as a "sexual deviatio[n]," Diagnostic and Statistical Manual of Mental Disorders 44 (2d ed.) (DSM-II). It was not until the sixth printing of the DSM-II in 1973 that this was changed. 23

 *1770 Society's treatment of homosexuality and homosexual conduct was consistent with this understanding. Sodomy was a crime in every State but Illinois, see W. Eskridge, Dishonorable Passions 387-407 (2008), and in the District of Columbia, a law enacted by Congress made sodomy a felony punishable by imprisonment for up to 10 years and permitted the indefinite civil commitment of "sexual psychopath[s]," Act of June 9, 1948, §§ 104, 201-207, 62 Stat. 347 -349. 24

 This view of homosexuality was reflected in the rules governing the federal work force. In 1964, federal "[a]gencies could deny homosexual men and women employment because of their sexual orientation," and this practice continued until 1975. GAO, D. Heivilin, Security Clearances: Consideration of Sexual Orientation in the Clearance Process 2 (GAO/NSIAD-95-21, 1995). See, e.g. , Anonymous v. Macy , 398 F.2d 317 , 318 (CA5 1968) (affirming dismissal of postal employee for homosexual acts).

 In 1964, individuals who were known to be homosexual could not obtain security clearances, and any who possessed clearances were likely to lose them if their orientation was discovered. A 1953 Executive Order provided that background investigations should look for evidence of "sexual perversion," as well as "[a]ny criminal, infamous, dishonest, immoral, or notoriously disgraceful conduct." Exec. Order No. 10450, § 8(a)(1)(iii), 3 CFR 938 (1949-1953 Comp.). "Until about 1991, when agencies began to change their security policies and practices regarding sexual orientation, there were a number of documented cases where defense civilian or contractor employees' security clearances were denied or revoked because of their sexual orientation." GAO, Security Clearances, at 2. See, e.g. , Adams v. Laird , 420 F.2d 230 , 240 (CADC 1969) (upholding denial of security clearance to defense contractor employee because he had "engaged in repeated homosexual acts"); see also Webster v. Doe , 486 U.S. 592 , 595, 601, 108 S.Ct. 2047 , 100 L.Ed.2d 632 (1988) (concluding that decision to fire a particular individual because he was homosexual fell within the "discretion" of the Director of Central Intelligence under the National Security Act of 1947 and thus was unreviewable under the APA).

 The picture in state employment was similar. In 1964, it was common for States to bar homosexuals from serving as teachers. An article summarizing the situation 15 years after Title VII became law reported that "[a]ll states have statutes that permit the revocation of teaching certificates (or credentials) for immorality, moral turpitude, or unprofessionalism," and, the survey added, "[h]omosexuality is considered to fall within all three categories." 25

 The situation in California is illustrative. California laws prohibited individuals who engaged in "immoral conduct" (which was construed to include homosexual behavior), as well as those convicted of "sex offenses" (like sodomy), from employment as teachers. Cal. Educ. Code Ann. §§ 13202, 13207, 13209, 13218, 13255 (West 1960). The teaching certificates of individuals convicted of engaging in homosexual acts were *1771 revoked. See, e.g. , Sarac v. State Bd. of Ed. , 249 Cal.App.2d 58 , 62-64, 57 Cal.Rptr. 69 , 72-73 (1967) (upholding revocation of secondary teaching credential from teacher who was convicted of engaging in homosexual conduct on public beach), overruled in part, Morrison v. State Bd. of Ed. , 1 Cal.3d 214 , 461 P.2d 375 , 82 Cal.Rptr. 175 (1969).

 In Florida, the legislature enacted laws authorizing the revocation of teaching certificates for "misconduct involving moral turpitude," Fla. Stat. Ann. § 229.08 (16) (1961), and this law was used to target homosexual conduct. In 1964, a legislative committee was wrapping up a 6-year campaign to remove homosexual teachers from public schools and state universities. As a result of these efforts, the state board of education apparently revoked at least 71 teachers' certificates and removed at least 14 university professors. Eskridge, Dishonorable Passions, at 103.

 Individuals who engaged in homosexual acts also faced the loss of other occupational licenses, such as those needed to work as a "lawyer, doctor, mortician, [or] beautician." 26 See, e.g. , Florida Bar v. Kay , 232 So.2d 378 (Fla. 1970) (attorney disbarred after conviction for homosexual conduct in public bathroom).

 In 1964 and for many years thereafter, homosexuals were barred from the military. See, e.g. , Army Reg. 635-89, § I(2) (a) (July 15, 1966) ("Personnel who voluntarily engage in homosexual acts, irrespective of sex, will not be permitted to serve in the Army in any capacity, and their prompt separation is mandatory"); Army Reg. 600-443, § I(2) (April 10, 1953) (similar). Prohibitions against homosexual conduct by members of the military were not eliminated until 2010. See Don't Ask, Don't Tell Repeal Act of 2010, 124 Stat. 3515 (repealing 10 U.S.C. § 654 , which required members of the Armed Forces to be separated for engaging in homosexual conduct).

 Homosexuals were also excluded from entry into the United States. The Immigration and Nationality Act of 1952 (INA) excluded aliens "afflicted with psychopathic personality." 8 U.S.C. § 1182 (a)(4) (1964 ed.). In Boutilier v. INS , 387 U.S. 118 , 120-123, 87 S.Ct. 1563 , 18 L.Ed.2d 661 (1967), this Court, relying on the INA's legislative history, interpreted that term to encompass homosexuals and upheld an alien's deportation on that ground. Three Justices disagreed with the majority's interpretation of the phrase "psychopathic personality." 27 But it apparently did not occur to anyone to argue that the Court's interpretation was inconsistent with the INA's express prohibition of discrimination "because of sex." That was how our society-and this Court-saw things a half century ago. Discrimination because of sex and discrimination because of sexual orientation were viewed as two entirely different concepts.

 To its credit, our society has now come to recognize the injustice of past practices, and this recognition provides the impetus to "update" Title VII. But that is not our job. Our duty is to understand what the terms of Title VII were understood to mean when enacted, and in doing so, we must take into account the societal norms of that time. We must therefore ask *1772 whether ordinary Americans in 1964 would have thought that discrimination because of "sex" carried some exotic meaning under which private-sector employers would be prohibited from engaging in a practice that represented the official policy of the Federal Government with respect to its own employees. We must ask whether Americans at that time would have thought that Title VII banned discrimination against an employee for engaging in conduct that Congress had made a felony and a ground for civil commitment.

 The questions answer themselves. Even if discrimination based on sexual orientation or gender identity could be squeezed into some arcane understanding of sex discrimination, the context in which Title VII was enacted would tell us that this is not what the statute's terms were understood to mean at that time. To paraphrase something Justice Scalia once wrote, "our job is not to scavenge the world of English usage to discover whether there is any possible meaning" of discrimination because of sex that might be broad enough to encompass discrimination because of sexual orientation or gender identity. Chisom v. Roemer , 501 U.S. 380 , 410, 111 S.Ct. 2354 , 115 L.Ed.2d 348 (1991) (dissenting opinion). Without strong evidence to the contrary (and there is none here), our job is to ascertain and apply the " ordinary meaning" of the statute. Ibid . And in 1964, ordinary Americans most certainly would not have understood Title VII to ban discrimination because of sexual orientation or gender identity.

 The Court makes a tiny effort to suggest that at least some people in 1964 might have seen what Title VII really means. Ante , at 1750 - 1751. What evidence does it adduce? One complaint filed in 1969, another filed in 1974, and arguments made in the mid-1970s about the meaning of the Equal Rights Amendment. Ibid . To call this evidence merely feeble would be generous.

 C

 While Americans in 1964 would have been shocked to learn that Congress had enacted a law prohibiting sexual orientation discrimination, they would have been bewildered to hear that this law also forbids discrimination on the basis of "transgender status" or "gender identity," terms that would have left people at the time scratching their heads. The term "transgender" is said to have been coined " 'in the early 1970s,' " 28 and the term "gender identity," now understood to mean "[a]n internal sense of being male, female or something else," 29 apparently first appeared in an academic article in 1964. 30 Certainly, neither term was in common parlance; indeed, dictionaries of the time *1773 still primarily defined the word "gender" by reference to grammatical classifications. See, e.g. , American Heritage Dictionary, at 548 (def. 1(a)) ("Any set of two or more categories, such as masculine, feminine, and neuter, into which words are divided ... and that determine agreement with or the selection of modifiers, referents, or grammatical forms").

 While it is likely true that there have always been individuals who experience what is now termed "gender dysphoria," i.e. , "[d]iscomfort or distress related to an incongruence between an individual's gender identity and the gender assigned at birth," 31 the current understanding of the concept postdates the enactment of Title VII. Nothing resembling what is now called gender dysphoria appeared in either DSM-I (1952) or DSM-II (1968). It was not until 1980 that the APA, in DSM-III, recognized two main psychiatric diagnoses related to this condition, "Gender Identity Disorder of Childhood" and "Transsexualism" in adolescents and adults. 32 DSM-III, at 261-266.

 The first widely publicized sex reassignment surgeries in the United States were not performed until 1966, 33 and the great majority of physicians surveyed in 1969 thought that an individual who sought sex reassignment surgery was either " 'severely neurotic' " or " 'psychotic.' " 34

 It defies belief to suggest that the public meaning of discrimination because of sex in 1964 encompassed discrimination on the basis of a concept that was essentially unknown to the public at that time.

 1

 The Court's main excuse for entirely ignoring the social context in which Title VII was enacted is that the meaning of Title VII's prohibition of discrimination because of sex is clear, and therefore it simply does not matter whether people in 1964 were "smart enough to realize" what its language means. Hively, 853 F.3d at 357 (Posner, J., concurring). According to the Court, an argument that looks to the societal norms of those times represents an impermissible attempt to displace the statutory language. Ante , at 1750 - 1751.

 The Court's argument rests on a false premise. As already explained at length, the text of Title VII does not prohibit discrimination because of sexual orientation or gender identity. And what the public thought about those issues in 1964 is relevant and important, not because it provides a ground for departing from the statutory text, but because it helps to explain what the text was understood to mean when adopted.

 In arguing that we must put out of our minds what we know about the time when Title VII was enacted, the Court relies on Justice Scalia's opinion for the Court in Oncale v. Sundowner Offshore Services, Inc. , 523 U.S. 75 , 118 S.Ct. 998 , 140 L.Ed.2d 201 (1998). But Oncale is nothing like these cases, and no one should be taken in by the majority's effort to enlist Justice Scalia in its updating project.

 *1774 The Court's unanimous decision in Oncale was thoroughly unremarkable. The Court held that a male employee who alleged that he had been sexually harassed at work by other men stated a claim under Title VII. Although the impetus for Title VII's prohibition of sex discrimination was to protect women, anybody reading its terms would immediately appreciate that it applies equally to both sexes, and by the time Oncale reached the Court, our precedent already established that sexual harassment may constitute sex discrimination within the meaning of Title VII. See Meritor Savings Bank, FSB v. Vinson , 477 U.S. 57 , 106 S.Ct. 2399 , 91 L.Ed.2d 49 (1986). Given these premises, syllogistic reasoning dictated the holding.

 What today's decision latches onto are Oncale 's comments about whether " 'male-on-male sexual harassment' " was on Congress's mind when it enacted Title VII. Ante , at 1751 (quoting 523 U.S. at 79 , 118 S.Ct. 998 ). The Court in Oncale observed that this specific type of behavior "was assuredly not the principal evil Congress was concerned with when it enacted Title VII," but it found that immaterial because "statutory prohibitions often go beyond the principal evil to cover reasonably comparable evils, and it is ultimately the provisions of our laws rather than the principal concerns of our legislators by which we are governed." 523 U.S. at 79 , 118 S.Ct. 998 (emphasis added).

 It takes considerable audacity to read these comments as committing the Court to a position on deep philosophical questions about the meaning of language and their implications for the interpretation of legal rules. These comments are better understood as stating mundane and uncontroversial truths. Who would argue that a statute applies only to the "principal evils" and not lesser evils that fall within the plain scope of its terms? Would even the most ardent "purposivists" and fans of legislative history contend that congressional intent is restricted to Congress's " principal concerns"?

 Properly understood, Oncale does not provide the slightest support for what the Court has done today. For one thing, it would be a wild understatement to say that discrimination because of sexual orientation and transgender status was not the "principal evil" on Congress's mind in 1964. Whether we like to admit it now or not, in the thinking of Congress and the public at that time, such discrimination would not have been evil at all.

 But the more important difference between these cases and Oncale is that here the interpretation that the Court adopts does not fall within the ordinary meaning of the statutory text as it would have been understood in 1964. To decide for the defendants in Oncale , it would have been necessary to carve out an exception to the statutory text. Here, no such surgery is at issue. Even if we totally disregard the societal norms of 1964, the text of Title VII does not support the Court's holding. And the reasoning of Oncale does not preclude or counsel against our taking those norms into account. They are relevant, not for the purpose of creating an exception to the terms of the statute, but for the purpose of better appreciating how those terms would have been understood at the time.

 The Court argues that two other decisions-- Phillips v. Martin Marietta Corp. , 400 U.S. 542 , 91 S.Ct. 496 , 27 L.Ed.2d 613 (1971) ( per curiam ), and Los Angeles Dept. of Water and Power v. Manhart , 435 U.S. 702 , 98 S.Ct. 1370 , 55 L.Ed.2d 657 (1978) --buttress its decision, but those cases merely held that Title VII prohibits employer conduct that plainly constitutes discrimination *1775 because of biological sex. In Philips , the employer treated women with young children less favorably than men with young children. In Manhart , the employer required women to make larger pension contributions than men. It is hard to see how these holdings assist the Court.

 The Court extracts three "lessons" from Phillips , Manhart , and Oncale , but none sheds any light on the question before us. The first lesson is that "it's irrelevant what an employer might call its discriminatory practice, how others might label it, or what else might motivate it." Ante , at 1744. This lesson is obviously true but proves nothing. As to the label attached to a practice, has anyone ever thought that the application of a law to a person's conduct depends on how it is labeled? Could a bank robber escape conviction by saying he was engaged in asset enhancement? So if an employer discriminates because of sex, the employer is liable no matter what it calls its conduct, but if the employer's conduct is not sex discrimination, the statute does not apply. Thus, this lesson simply takes us back to the question whether discrimination because of sexual orientation or gender identity is a form of discrimination because of biological sex. For reasons already discussed, see Part I-A, supra , it is not.

 It likewise proves nothing of relevance here to note that an employer cannot escape liability by showing that discrimination on a prohibited ground was not its sole motivation. So long as a prohibited ground was a motivating factor, the existence of other motivating factors does not defeat liability.

 The Court makes much of the argument that "[i]n Phillips , the employer could have accurately spoken of its policy as one based on 'motherhood.' " Ante , at 1744; see also ante, at 1745. But motherhood, by definition, is a condition that can be experienced only by women, so a policy that distinguishes between motherhood and parenthood is necessarily a policy that draws a sex-based distinction. There was sex discrimination in Phillips , because women with children were treated disadvantageously compared to men with children.

 Lesson number two-"the plaintiff 's sex need not be the sole or primary cause of the employer's adverse action," ante , at 1744-is similarly unhelpful. The standard of causation in these cases is whether sex is necessarily a "motivating factor" when an employer discriminates on the basis of sexual orientation or gender identity. 42 U.S.C. § 2000e-2(m). But the essential question-whether discrimination because of sexual orientation or gender identity constitutes sex discrimination-would be the same no matter what causation standard applied. The Court's extensive discussion of causation standards is so much smoke.

 Lesson number three--"an employer cannot escape liability by demonstrating that it treats males and females comparably as groups," ante , at 1744, is also irrelevant. There is no dispute that discrimination against an individual employee based on that person's sex cannot be justified on the ground that the employer's treatment of the average employee of that sex is at least as favorable as its treatment of the average employee of the opposite sex. Nor does it matter if an employer discriminates against only a subset of men or women, where the same subset of the opposite sex is treated differently, as in Phillips . That is not the issue here. An employer who discriminates equally on the basis of sexual orientation or gender identity applies the same criterion to every affected individual regardless of sex. See Part I-A, supra .

 *1776 III

 Because the opinion of the Court flies a textualist flag, I have taken pains to show that it cannot be defended on textualist grounds. But even if the Court's textualist argument were stronger, that would not explain today's decision. Many Justices of this Court, both past and present, have not espoused or practiced a method of statutory interpretation that is limited to the analysis of statutory text. Instead, when there is ambiguity in the terms of a statute, they have found it appropriate to look to other evidence of "congressional intent," including legislative history.

 So, why in these cases are congressional intent and the legislative history of Title VII totally ignored? Any assessment of congressional intent or legislative history seriously undermines the Court's interpretation.

 B

 As the Court explained in General Elec. Co. v. Gilbert , 429 U.S. 125 , 143, 97 S.Ct. 401 , 50 L.Ed.2d 343 (1976), the legislative history of Title VII's prohibition of sex discrimination is brief, but it is nevertheless revealing. The prohibition of sex discrimination was "added to Title VII at the last minute on the floor of the House of Representatives," Meritor Savings Bank , 477 U.S. at 63 , 106 S.Ct. 2399 , by Representative Howard Smith, the Chairman of the Rules Committee. See 110 Cong. Rec. 2577 (1964). Representative Smith had been an ardent opponent of the civil rights bill, and it has been suggested that he added the prohibition against discrimination on the basis of "sex" as a poison pill. See, e.g. , Ulane v. Eastern Airlines, Inc. , 742 F.2d 1081 , 1085 (CA7 1984). On this theory, Representative Smith thought that prohibiting employment discrimination against women would be unacceptable to Members who might have otherwise voted in favor of the bill and that the addition of this prohibition might bring about the bill's defeat. 35 But if Representative Smith had been looking for a poison pill, prohibiting discrimination on the basis of sexual orientation or gender identity would have been far more potent. However, neither Representative Smith nor any other Member said one word about the possibility that the prohibition of sex discrimination might have that meaning. Instead, all the debate concerned discrimination on the basis of biological sex. 36 See 110 Cong. Rec. 2577-2584.

 Representative Smith's motivations are contested, 883 F.3d at 139-140 (Lynch, J., dissenting), but whatever they were, the meaning of the adoption of the prohibition of sex discrimination is clear. It was no accident. It grew out of "a long history of women's rights advocacy that had increasingly been gaining mainstream recognition and acceptance," and it marked a landmark achievement in the path toward fully *1777 equal rights for women. Id. , at 140. "Discrimination against gay women and men, by contrast, was not on the table for public debate ... [i]n those dark, pre-Stonewall days." Ibid .

 For those who regard congressional intent as the touchstone of statutory interpretation, the message of Title VII's legislative history cannot be missed.

 C

 Post-enactment events only clarify what was apparent when Title VII was enacted. As noted, bills to add "sexual orientation" to Title VII's list of prohibited grounds were introduced in every Congress beginning in 1975, see supra , at 1754 - 1755, and two such bills were before Congress in 1991 37 when it made major changes in Title VII. At that time, the three Courts of Appeals to reach the issue had held that Title VII does not prohibit discrimination because of sexual orientation, 38 two other Circuits had endorsed that interpretation in dicta, 39 and no Court of Appeals had held otherwise. Similarly, the three Circuits to address the application of Title VII to transgender persons had all rejected the argument that it covered discrimination on this basis. 40 These were also the positions of the EEOC. 41 In enacting substantial changes to Title VII, the 1991 Congress abrogated numerous judicial decisions with which it disagreed. If it also disagreed with the decisions regarding sexual orientation and transgender discrimination, it could have easily overruled those as well, but it did not do so. 42

 After 1991, six other Courts of Appeals reached the issue of sexual orientation discrimination, and until 2017, every single Court of Appeals decision understood Title VII's prohibition of "discrimination because of sex" to mean discrimination because of biological sex. See, e.g. , Higgins v. New Balance Athletic Shoe, Inc. , 194 F.3d 252 , 259 (CA1 1999) ; Simonton v. Runyon , 232 F.3d 33 , 36 (CA2 2000) ; Bibby v. Philadelphia Coca Cola Bottling Co. , 260 F.3d 257 , 261 (CA3 2001), cert. denied, 534 U.S. 1155 , 122 S.Ct. 1126 , 151 L.Ed.2d 1018 (2002) ; Wrightson v. Pizza Hut of Am., Inc. , 99 F.3d 138 , 143 (CA4 1996) ; Hamm v. Weyauwega Milk Products, Inc. , 332 F.3d 1058 , 1062 (CA7 2003) ; Medina v. Income Support Div., N. M. , 413 F.3d 1131 , 1135 (CA10 2005) ; Evans v. Georgia Regional Hospital , 850 F.3d 1248 , 1255 (CA11), cert. denied, 583 U.S. ----, 138 S.Ct. 557 , 199 L.Ed.2d 446 (2017). Similarly, the other Circuit to formally address *1778 whether Title VII applies to claims of discrimination based on transgender status had also rejected the argument, creating unanimous consensus prior to the Sixth Circuit's decision below. See Etsitty v. Utah Transit Authority , 502 F.3d 1215 , 1220-1221 (CA10 2007).

 The Court observes that "[t]he people are entitled to rely on the law as written, without fearing that courts might disregard its plain terms," ante , at 1749, but it has no qualms about disregarding over 50 years of uniform judicial interpretation of Title VII's plain text. Rather, the Court makes the jaw-dropping statement that its decision exemplifies "judicial humility." Ante , at 1753. Is it humble to maintain, not only that Congress did not understand the terms it enacted in 1964, but that all the Circuit Judges on all the pre-2017 cases could not see what the phrase discrimination "because of sex" really means? If today's decision is humble, it is sobering to imagine what the Court might do if it decided to be bold.

 IV

 What the Court has done today--interpreting discrimination because of "sex" to encompass discrimination because of sexual orientation or gender identity--is virtually certain to have far-reaching consequences. Over 100 federal statutes prohibit discrimination because of sex. See Appendix C, infra ; e.g. , 20 U.S.C. § 1681 (a) (Title IX); 42 U.S.C. § 3631 (Fair Housing Act); 15 U.S.C. 1691(a)(1) (Equal Credit Opportunity Act). The briefs in these cases have called to our attention the potential effects that the Court's reasoning may have under some of these laws, but the Court waves those considerations aside. As to Title VII itself, the Court dismisses questions about "bathrooms, locker rooms, or anything else of the kind." Ante , at 1753. And it declines to say anything about other statutes whose terms mirror Title VII's.

 The Court's brusque refusal to consider the consequences of its reasoning is irresponsible. If the Court had allowed the legislative process to take its course, Congress would have had the opportunity to consider competing interests and might have found a way of accommodating at least some of them. In addition, Congress might have crafted special rules for some of the relevant statutes. But by intervening and proclaiming categorically that employment discrimination based on sexual orientation or gender identity is simply a form of discrimination because of sex, the Court has greatly impeded-and perhaps effectively ended-any chance of a bargained legislative resolution. Before issuing today's radical decision, the Court should have given some thought to where its decision would lead.

 As the briefing in these cases has warned, the position that the Court now adopts will threaten freedom of religion, freedom of speech, and personal privacy and safety. No one should think that the Court's decision represents an unalloyed victory for individual liberty.

 I will briefly note some of the potential consequences of the Court's decision, but I do not claim to provide a comprehensive survey or to suggest how any of these issues should necessarily play out under the Court's reasoning. 43

 "[B]athrooms, locker rooms, [and other things] of [that] kind." The Court may wish to avoid this subject, but it is a matter of concern to many people who are reticent about disrobing or using toilet facilities *1779 in the presence of individuals whom they regard as members of the opposite sex. For some, this may simply be a question of modesty, but for others, there is more at stake. For women who have been victimized by sexual assault or abuse, the experience of seeing an unclothed person with the anatomy of a male in a confined and sensitive location such as a bathroom or locker room can cause serious psychological harm. 44

 Under the Court's decision, however, transgender persons will be able to argue that they are entitled to use a bathroom or locker room that is reserved for persons of the sex with which they identify, and while the Court does not define what it means by a transgender person, the term may apply to individuals who are "gender fluid," that is, individuals whose gender identity is mixed or changes over time. 45 Thus, a person who has not undertaken any physical transitioning may claim the right to use the bathroom or locker room assigned to the sex with which the individual identifies at that particular time. The Court provides no clue why a transgender person's claim to such bathroom or locker room access might not succeed.

 A similar issue has arisen under Title IX, which prohibits sex discrimination by any elementary or secondary school and any college or university that receives federal financial assistance. 46 In 2016, a Department of Justice advisory warned that barring a student from a bathroom assigned to individuals of the gender with which the student identifies constitutes unlawful sex discrimination, 47 and some lower court decisions have agreed. See Whitaker v. Kenosha Unified School Dist. No. 1 Bd. of Ed. , 858 F.3d 1034 , 1049 (CA7 2017) ; G. G. v. Gloucester Cty. School Bd. , 822 F.3d 709 , 715 (CA4 2016), vacated and remanded, 580 U.S. ----, 137 S.Ct. 1239 , 197 L.Ed.2d 460 (2017) ; Adams v. School Bd. of St. Johns Cty. , 318 F.Supp.3d 1293 , 1325 (MD Fla. 2018) ; cf. Doe v. Boyertown Area

 School Dist. , 897 F.3d 518 , 533 (CA3 2018), cert. denied, 587 U.S. ----, 139 S.Ct. 2636 , 204 L.Ed.2d 300 (2019).

 Women's sports . Another issue that may come up under both Title VII and Title IX is the right of a transgender individual to participate on a sports team or in an athletic competition previously reserved for members of one biological sex. 48 This issue has already arisen under Title IX, where it threatens to undermine one of that law's major achievements, giving young women an equal opportunity to participate in sports. The effect of the Court's reasoning may be to force young women to compete against students who have a very significant biological advantage, including students who have the size and strength of a *1780 male but identify as female and students who are taking male hormones in order to transition from female to male. See, e.g. , Complaint in Soule v. Connecticut Assn. of Schools , No. 3:20-cv-00201 (D Conn., Apr. 17, 2020) (challenging Connecticut policy allowing transgender students to compete in girls' high school sports); Complaint in Hecox v. Little , No. 1:20-cv-00184 (D Idaho, Apr. 15, 2020) (challenging state law that bars transgender students from participating in school sports in accordance with gender identity). Students in these latter categories have found success in athletic competitions reserved for females. 49

 The logic of the Court's decision could even affect professional sports. Under the Court's holding that Title VII prohibits employment discrimination because of transgender status, an athlete who has the physique of a man but identifies as a woman could claim the right to play on a women's professional sports team. The owners of the team might try to claim that biological sex is a bona fide occupational qualification (BFOQ) under 42 U.S.C. § 2000e-2(e), but the BFOQ exception has been read very narrowly. See Dothard v. Rawlinson , 433 U.S. 321 , 334, 97 S.Ct. 2720 , 53 L.Ed.2d 786 (1977).

 Housing . The Court's decision may lead to Title IX cases against any college that resists assigning students of the opposite biological sex as roommates. A provision of Title IX, 20 U.S.C. § 1686 , allows schools to maintain "separate living facilities for the different sexes," but it may be argued that a student's "sex" is the gender with which the student identifies. 50 Similar claims may be brought under the Fair Housing Act. See 42 U.S.C. § 3604 .

 Employment by religious organizations . Briefs filed by a wide range of religious groups--Christian, Jewish, and Muslim--express deep concern that the position now adopted by the Court "will trigger open conflict with faithbased employment practices of numerous churches, synagogues, mosques, and other religious institutions." 51 They argue that "[r]eligious organizations need employees who actually live the faith," 52 and that compelling a religious organization to employ individuals whose conduct flouts the tenets of the organization's faith forces the group to communicate an objectionable message.

 *1781 This problem is perhaps most acute when it comes to the employment of teachers. A school's standards for its faculty "communicate a particular way of life to its students," and a "violation by the faculty of those precepts" may undermine the school's "moral teaching." 53 Thus, if a religious school teaches that sex outside marriage and sex reassignment procedures are immoral, the message may be lost if the school employs a teacher who is in a same-sex relationship or has undergone or is undergoing sex reassignment. Yet today's decision may lead to Title VII claims by such teachers and applicants for employment.

 At least some teachers and applicants for teaching positions may be blocked from recovering on such claims by the "ministerial exception" recognized in Hosanna-Tabor Evangelical Lutheran Church and School v. EEOC , 565 U.S. 171 , 132 S.Ct. 694 , 181 L.Ed.2d 650 (2012). Two cases now pending before the Court present the question whether teachers who provide religious instruction can be considered to be "ministers." 54 But even if teachers with those responsibilities qualify, what about other very visible school employees who may not qualify for the ministerial exception? Provisions of Title VII provide exemptions for certain religious organizations and schools "with respect to the employment of individuals of a particular religion to perform work connected with the carrying on" of the "activities" of the organization or school, 42 U.S.C. § 2000e-1(a) ; see also § 2000e-2(e)(2), but the scope of these provisions is disputed, and as interpreted by some lower courts, they provide only narrow protection. 55

 Healthcare . Healthcare benefits may emerge as an intense battleground under the Court's holding. Transgender employees have brought suit under Title VII to challenge employer-provided health insurance plans that do not cover costly sex reassignment surgery. 56 Similar claims have been brought under the Affordable Care Act (ACA), which broadly prohibits sex discrimination in the provision of healthcare. 57

 *1782 Such claims present difficult religious liberty issues because some employers and healthcare providers have strong religious objections to sex reassignment procedures, and therefore requiring them to pay for or to perform these procedures will have a severe impact on their ability to honor their deeply held religious beliefs.

 Freedom of speech . The Court's decision may even affect the way employers address their employees and the way teachers and school officials address students. Under established English usage, two sets of sex-specific singular personal pronouns are used to refer to someone in the third person (he, him, and his for males; she, her, and hers for females). But several different sets of gender-neutral pronouns have now been created and are preferred by some individuals who do not identify as falling into either of the two traditional categories. 58 Some jurisdictions, such as New York City, have ordinances making the failure to use an individual's preferred pronoun a punishable offense, 59 and some colleges have similar rules. 60 After today's decision, plaintiffs may claim that the failure to use their preferred pronoun violates one of the federal laws prohibiting sex discrimination. See Prescott v. Rady Children's Hospital San Diego , 265 F.Supp.3d 1090 , 1098-1100 (SD Cal. 2017) (hospital staff 's refusal to use preferred pronoun *1783 violates ACA). 61

 The Court's decision may also pressure employers to suppress any statements by employees expressing disapproval of same-sex relationships and sex reassignment procedures. Employers are already imposing such restrictions voluntarily, and after today's decisions employers will fear that allowing employees to express their religious views on these subjects may give rise to Title VII harassment claims.

 Constitutional claims . Finally, despite the important differences between the Fourteenth Amendment and Title VII, the Court's decision may exert a gravitational pull in constitutional cases. Under our precedents, the Equal Protection Clause prohibits sex-based discrimination unless a "heightened" standard of review is met. Sessions v. Morales-Santana , 582 U.S. ----, ----, 137 S.Ct. 1678 , 1689, 198 L.Ed.2d 150 (2017); United States v. Virginia , 518 U.S. 515 , 532-534, 116 S.Ct. 2264 , 135 L.Ed.2d 735 (1996). By equating discrimination because of sexual orientation or gender identity with discrimination because of sex, the Court's decision will be cited as a ground for subjecting all three forms of discrimination to the same exacting standard of review.

 Under this logic, today's decision may have effects that extend well beyond the domain of federal antidiscrimination statutes. This potential is illustrated by pending and recent lower court cases in which transgender individuals have challenged a variety of federal, state, and local laws and policies on constitutional grounds. See, e.g. , Complaint in Hecox , No. 1: 20-CV-00184 (state law prohibiting transgender students from competing in school sports in accordance with their gender identity); Second Amended Complaint in Karnoski v. Trump , No. 2:17-cv-01297 (WD Wash., July 31, 2019) (military's ban on transgender members); Kadel v. Folwell , ---- F. Supp. 3d ----, ---- - ----, 2020 WL 1169271 , *10-*11 (MDNC, Mar. 11, 2020) (state health plan's exclusion of coverage for sex reassignment procedures); Complaint in Gore v.

 Although the Court does not want to think about the consequences of its decision, we will not be able to avoid those issues for long. The entire Federal Judiciary will be mired for years in disputes about the reach of the Court's reasoning.

 * * *

 The updating desire to which the Court succumbs no doubt arises from humane and generous impulses. Today, many *1784 Americans know individuals who are gay, lesbian, or transgender and want them to be treated with the dignity, consideration, and fairness that everyone deserves. But the authority of this Court is limited to saying what the law is .

 The Court itself recognizes this:

 "The place to make new legislation ... lies in Congress. When it comes to statutory interpretation, our role is limited to applying the law's demands as faithfully as we can in the cases that come before us." Ante , at 1753.
 It is easy to utter such words. If only the Court would live by them.

 I respectfully dissent.

 Webster's New International Dictionary 2296 (2d ed. 1953):

 sex (seks), n. [F. sexe , fr. L. sexus; prob. orig., division, and akin to L. secare to cut. See SECTION .] 1. One of the two divisions of organisms formed on the distinction of male and female; males or females collectively. 2. The sum of the peculiarities of structure and function that distinguish a male from a female organism; the character of being male or female, or of pertaining to the distinctive function of the male or female in reproduction. Conjugation, or fertilization (union of germplasm of two individuals), a process evidently of great but not readily explainable importance in the perpetuation of most organisms, seems to be the function of differentiation of sex, which occurs in nearly all organisms at least at some stage in their life history. Sex is manifested in the conjugating cells by the larger size, abundant food material, and immobility of the female gamete ( egg , egg cell , or ovum ), and the small size and the locomotive power of the male gamete ( spermatozoon or spermatozoid ), and in the adult organisms often by many structural, physiological, and (in higher forms) psychological characters, aside from the necessary modification of the reproductive apparatus. Cf. HERMAPHRODITE , 1. In botany the term sex is often extended to the distinguishing peculiarities of staminate and pistillate flowers, and hence in dioecious plants to the individuals bearing them.
 In many animals and plants the body and germ cells have been shown to contain one or more chromosomes of a special kind (called sex chromosomes; idiochromosomes; accessory chromosomes ) in addition to the ordinary paired autosomes. These special chromosomes serve to determine sex. In the simplest case, the male germ cells are of two types, one with and one without a single extra chromosome ( X chromosome , or monosome ). The egg cells in this case all possess an X chromosome , and on fertilization by the two types of sperm, male and female zygotes result, of respective constitution X , and XX . In many other animals and plants (probably including man) the male organism produces two types of gametes, one possessing an X chromosome , the other a Y chromosome , these being visibly different members of a pair of chromosomes present in the diploid state. In this case also, the female organism is XX , the eggs X , and the zygotes respectively male ( XY ) and female ( XX ). In another type of sex determination, as in certain moths and possibly in the fowl, the female produces two kinds of eggs, the male only one kind of sperm. Each type of egg contains one member of a pair of differentiated chromosomes, *1785 called respectively Z chromosomes and W chromosomes , while all the sperm cells contain a Z chromosome. In fertilization, union of a Z with a W gives rise to a female, while union of two Z chromosomes produces a male. Cf. SECONDARY SEX CHARACTER .
 3. a The sphere of behavior dominated by the relations between male and female. b Psychoanalysis . By extension, the whole sphere of behavior related even indirectly to the sexual functions and embracing all affectionate and pleasure-seeking conduct.
 4. Phenomena of sexual instincts and their manifestations.
 5. Sect;-a confused use.
 Syn. - SEX, GENDER. SEX refers to physiological distinctions; GENDER , to distinctions in grammar.
 - the sex . The female sex; women, in general.
 sex, adj . Based on or appealing to sex.
 sex, v. t. To determine the sex of, as skeletal remains.

 Section 7(b) of H.R. 5 strikes the term "sex" in 42 U.S.C. § 2000e-2 and inserts: "SEX (INCLUDING SEXUAL ORIENTATION AND GENDER IDENTITY)."

 That is what Judge Posner did in the Seventh Circuit case holding that Title VII prohibits discrimination because of sexual orientation. See Hively v. Ivy Tech Community College of Ind. , 853 F.3d 339 (2017) (en banc). Judge Posner agreed with that result but wrote:

 " I would prefer to see us acknowledge openly that today we, who are judges rather than members of Congress, are imposing on a half-century-old statute a meaning of 'sex discrimination' that the Congress that enacted it would not have accepted ." Id. , at 357 (concurring opinion) (emphasis added).

 The Court does not define what it means by "transgender status," but the American Psychological Association describes "transgender" as "[a]n umbrella term encompassing those whose gender identities or gender roles differ from those typically associated with the sex they were assigned at birth." A Glossary: Defining Transgender Terms, 49 Monitor on Psychology 32 (Sept. 2018), https://www.apa.org/monitor/2018/09/ce-corner-glossary. It defines "gender identity" as "[a]n internal sense of being male, female or something else, which may or may not correspond to an individual's sex assigned at birth or sex characteristics." Ibid. Under these definitions, there is no apparent difference between discrimination because of transgender status and discrimination because of gender identity.

 The EEOC first held that "discrimination against a transgender individual because that person is transgender" violates Title VII in 2012 in Macy v. Holder , 2012 WL 1435995 , *11 (Apr. 20, 2012), though it earlier advanced that position in an amicus brief in Federal District Court in 2011, ibid ., n. 16. It did not hold that discrimination on the basis of sexual orientation violated Title VII until 2015. See Baldwin v. Foxx , 2015 WL 4397641 (July 15, 2015).

 "Sexual orientation refers to a person's erotic response tendency or sexual attractions, be they directed toward individuals of the same sex (homosexual), the other sex (heterosexual), or both sexes (bisexual)." 1 B. Sadock, V. Sadock, & P. Ruiz, Comprehensive Textbook of Psychiatry 2061 (9th ed. 2009); see also American Heritage Dictionary 1607 (5th ed. 2011) (defining "sexual orientation" as "[t]he direction of a person's sexual interest, as toward people of the opposite sex, the same sex, or both sexes"); Webster's New College Dictionary 1036 (3d ed. 2008) (defining "sexual orientation" as "[t]he direction of one's sexual interest toward members of the same, opposite, or both sexes").

 See n. 6, supra ; see also Sadock, supra, at 2063 ("transgender" refers to "any individual who identifies with and adopts the gender role of a member of the other biological sex").

 See Tr. of Oral Arg. in Nos. 17-1618, 17-1623, pp. 69-70 ("If there was that case, it might be the rare case in which sexual orientation discrimination is not a subset of sex"); see also id. , at 69 ("Somebody who comes in and says I'm not going to tell you what my sex is, but, believe me, I was fired for my sexual orientation, that person will lose").

 See also Brief for William N. Eskridge Jr. et al. as Amici Curiae 2 ("[T]here is no reasonable way to disentangle sex from same-sex attraction or transgender status").

 Reply Brief for Respondent Aimee Stephens in No. 18-107, p. 5.

 Notably, Title VII itself already suggests a line, which the Court ignores. The statute specifies that the terms "because of sex" and "on the basis of sex" cover certain conditions that are biologically tied to sex, namely, "pregnancy, childbirth, [and] related medical conditions." 42 U.S.C. § 2000e(k). This definition should inform the meaning of "because of sex" in Title VII more generally. Unlike pregnancy, neither sexual orientation nor gender identity is biologically linked to women or men.

 Two other Justices concurred in the judgment but did not comment on the issue of stereotypes. See id. , at 258-261, 109 S.Ct. 1775 (opinion of White, J.); id. , at 261-279, 109 S.Ct. 1775 (opinion of O'Connor, J.). And Justice Kennedy reiterated on behalf of the three Justices in dissent that "Title VII creates no independent cause of action for sex stereotyping," but he added that "[e]vidence of use by decisionmakers of sex stereotypes is, of course, quite relevant to the question of discriminatory intent." Id. , at 294, 109 S.Ct. 1775 .

 Notably, Title VII recognizes that in light of history distinctions on the basis of race are always disadvantageous, but it permits certain distinctions based on sex. Title 42 U.S.C. § 2000e-2(e)(1) allows for "instances where religion, sex, or national origin is a bona fide occupational qualification reasonably necessary to the normal operation of [a] particular business or enterprise." Race is wholly absent from this list.

 See American Heritage Dictionary 1188 (1969) (defining "sexual intercourse"); Webster's Third New International Dictionary 2082 (1966) (same); Random House Dictionary of the English Language 1308 (1966) (same).

 See also Chisom v. Roemer , 501 U.S. 380 , 405, 111 S.Ct. 2354 , 115 L.Ed.2d 348 (1991) (Scalia, J., dissenting) ("We are to read the words of [a statutory] text as any ordinary Member of Congress would have read them ... and apply the meaning so determined").

 J. Kennedy, Statement by the President on the Establishment of the President's Commission on the Status of Women 3 (Dec. 14, 1961) (emphasis added), https://www.jfklibrary.org/asset-viewer/archives/JFKPOF/093/JFKPOF-093-004.

 Analysis of the way Title VII's key language was used in books and articles during the relevant time period supports this conclusion. A study searched a vast database of documents from that time to determine how the phrase "discriminate against ... because of [some trait]" was used. Phillips, The Overlooked Evidence in the Title VII Cases: The Linguistic (and Therefore Textualist) Principle of Compositionality (manuscript, at 3) (May 11, 2020) (brackets in original), https://ssrn.com/abstract=3585940. The study found that the phrase was used to denote discrimination against "someone ... motivated by prejudice, or biased ideas or attitudes ... directed at people with that trait in particular." Id. , at 7 (emphasis deleted). In other words, " discriminate against " was "associated with negative treatment directed at members of a discrete group." Id., at 5. Thus, as used in 1964, "discrimination because of sex" would have been understood to mean discrimination against a woman or a man based on "unfair beliefs or attitudes" about members of that particular sex. Id., at 7.

 APA, Homosexuality and Sexual Orientation Disturbance : Proposed Change in DSM-II, 6th Printing, p. 44 (APA Doc. Ref. No. 730008, 1973) (reclassifying "homosexuality" as a "[s]exual orientation disturbance," a category "for individuals whose sexual interests are directed primarily toward people of the same sex and who are either disturbed by ... or wish to change their sexual orientation," and explaining that "homosexuality ... by itself does not constitute a psychiatric disorder"); see also APA, Diagnostic and Statistical Manual of Mental Disorders 281-282 (3d ed. 1980) (DSM-III) (similarly creating category of "Ego-dystonic Homosexuality" for "homosexuals for whom changing sexual orientation is a persistent concern," while observing that "homosexuality itself is not considered a mental disorder"); Obergefell v. Hodges , 576 U.S. 644 , 661, 135 S.Ct. 2584 , 192 L.Ed.2d 609 (2015).

 In 1981, after achieving home rule, the District attempted to decriminalize sodomy, see D. C. Act No. 4-69, but the House of Representatives vetoed the bill, H. Res. 208, 97th Cong., 1st Sess. (1981); 127 Cong. Rec. 22764-22779 (1981). Sodomy was not decriminalized in the District until 1995. See Anti-Sexual Abuse Act of 1994, § 501(b), 41 D. C. Reg. 53 (1995), enacted as D. C. Law 10-257.

Meyerowitz, How Sex Changed 213 (2002) (referring to founding of "Gender Identity Research Clinic" at UCLA in 1962). In his book, Sex and Gender, published in 1968, Robert Stoller referred to " gender identity " as "a working term" "associated with" his research team but noted that they were not "fixed on copyrighting the term or on defending the concept as one of the splendors of the scientific world."

 Like many cases in this Court, this case boils down to one fundamental question: Who decides? Title VII of the Civil Rights Act of 1964 prohibits employment discrimination "because of " an individual's "race, color, religion, sex, or national origin." The question here is whether Title VII should be expanded to prohibit employment discrimination because of sexual orientation. Under the Constitution's separation of powers, the responsibility to amend Title VII belongs to Congress and the President in the legislative process, not to this Court.

 The political branches are well aware of this issue. In 2007, the U.S. House of Representatives voted 235 to 184 to prohibit employment discrimination on the basis of sexual orientation. In 2013, the U.S. Senate voted 64 to 32 in favor of a similar ban. In 2019, the House again voted 236 to 173 to outlaw employment discrimination *1823 on the basis of sexual orientation. Although both the House and Senate have voted at different times to prohibit sexual orientation discrimination, the two Houses have not yet come together with the President to enact a bill into law.

 The policy arguments for amending Title VII are very weighty. The Court has previously stated, and I fully agree, that gay and lesbian Americans "cannot be treated as social outcasts or as inferior in dignity and worth." Masterpiece Cakeshop, Ltd. v. Colorado Civil Rights Comm'n , 584 U.S. ----, ----, 138 S.Ct. 1719 , 1727, 201 L.Ed.2d 35 (2018).

 But we are judges, not Members of Congress. And in Alexander Hamilton's words, federal judges exercise "neither Force nor Will, but merely judgment." The Federalist No. 78, p. 523 (J. Cooke ed. 1961). Under the Constitution's separation of powers, our role as judges is to interpret and follow the law as written, regardless of whether we like the result. Cf. Texas v. Johnson , 491 U.S. 397 , 420-421, 109 S.Ct. 2533 , 105 L.Ed.2d 342 (1989) (Kennedy, J., concurring). Our role is not to make or amend the law. As written, Title VII does not prohibit employment discrimination because of sexual orientation. 1

 I

 Title VII makes it unlawful for employers to discriminate because of "race, color, religion, sex, or national origin." 42 U.S.C. § 2000e-2(a)(1). 2 As enacted in 1964, Title VII did not prohibit other forms of employment discrimination, such as age discrimination, disability discrimination, or sexual orientation discrimination.

 Over time, Congress has enacted new employment discrimination laws. In 1967, Congress passed and President Johnson signed the Age Discrimination in Employment Act. 81 Stat. 602 . In 1973, Congress passed and President Nixon signed the Rehabilitation Act, which in substance prohibited disability discrimination against federal and certain other employees. 87 Stat. 355 . In 1990, Congress passed and President George H. W. Bush signed the comprehensive Americans with Disabilities Act. 104 Stat. 327 .

 To prohibit age discrimination and disability discrimination, this Court did not unilaterally rewrite or update the law. Rather, Congress and the President enacted new legislation, as prescribed by the Constitution's separation of powers.

 *1824 For several decades, Congress has considered numerous bills to prohibit employment discrimination based on sexual orientation. But as noted above, although Congress has come close, it has not yet shouldered a bill over the legislative finish line.

 In the face of the unsuccessful legislative efforts (so far) to prohibit sexual orientation discrimination, judges may not rewrite the law simply because of their own policy views. Judges may not update the law merely because they think that Congress does not have the votes or the fortitude. Judges may not predictively amend the law just because they believe that Congress is likely to do it soon anyway.

 If judges could rewrite laws based on their own policy views, or based on their own assessments of likely future legislative action, the critical distinction between legislative authority and judicial authority that undergirds the Constitution's separation of powers would collapse, thereby threatening the impartial rule of law and individual liberty. As James Madison stated: "Were the power of judging joined with the legislative, the life and liberty of the subject would be exposed to arbitrary controul, for the judge would then be the legislator ." The Federalist No. 47, at 326 (citing Montesquieu). If judges could, for example, rewrite or update securities laws or healthcare laws or gun laws or environmental laws simply based on their own policy views, the Judiciary would become a democratically illegitimate super-legislature-unelected, and hijacking the important policy decisions reserved by the Constitution to the people's elected representatives.

 Because judges interpret the law as written, not as they might wish it were written, the first 10 U.S. Courts of Appeals to consider whether Title VII prohibits sexual orientation discrimination all said no. Some 30 federal judges considered the question. All 30 judges said no, based on the text of the statute. 30 out of 30.

 But in the last few years, a new theory has emerged. To end-run the bedrock separation-of-powers principle that courts may not unilaterally rewrite statutes, the plaintiffs here (and, recently, two Courts of Appeals) have advanced a novel and creative argument. They contend that discrimination "because of sexual orientation" and discrimination "because of sex" are actually not separate categories of discrimination after all. Instead, the theory goes, discrimination because of sexual orientation always qualifies as discrimination because of sex: When a gay man is fired because he is gay, he is fired because he is attracted to men, even though a similarly situated woman would not be fired just because she is attracted to men. According to this theory, it follows that the man has been fired, at least as a literal matter, because of his sex.

 Under this literalist approach, sexual orientation discrimination automatically qualifies as sex discrimination, and Title VII's prohibition against sex discrimination therefore also prohibits sexual orientation discrimination-and actually has done so since 1964, unbeknownst to everyone. Surprisingly, the Court today buys into this approach. Ante , at 1758 - 1760.

 For the sake of argument, I will assume that firing someone because of their sexual orientation may, as a very literal matter, entail making a distinction based on sex. But to prevail in this case with their literalist approach, the plaintiffs must also establish one of two other points. The plaintiffs must establish that courts, when interpreting a statute, adhere to literal meaning rather than ordinary meaning. Or alternatively, the plaintiffs must establish that the ordinary meaning of "discriminate *1825 because of sex"-not just the literal meaning-encompasses sexual orientation discrimination. The plaintiffs fall short on both counts.

 First , courts must follow ordinary meaning, not literal meaning. And courts must adhere to the ordinary meaning of phrases, not just the meaning of the words in a phrase.

 There is no serious debate about the foundational interpretive principle that courts adhere to ordinary meaning, not literal meaning, when interpreting statutes. As Justice Scalia explained, "the good textualist is not a literalist." A. Scalia, A Matter of Interpretation 24 (1997). Or as Professor Eskridge stated: The "prime directive in statutory interpretation is to apply the meaning that a reasonable reader would derive from the text of the law," so that "for hard cases as well as easy ones, the ordinary meaning (or the 'everyday meaning' or the 'commonsense' reading) of the relevant statutory text is the anchor for statutory interpretation." W. Eskridge, Interpreting Law 33, 34-35 (2016) (footnote omitted). Or as Professor Manning put it, proper statutory interpretation asks "how a reasonable person, conversant with the relevant social and linguistic conventions, would read the text in context. This approach recognizes that the literal or dictionary definitions of words will often fail to account for settled nuances or background conventions that qualify the literal meaning of language and, in particular, of legal language." Manning, The Absurdity Doctrine, 116 Harv. L. Rev. 2387 , 2392-2393 (2003). Or as Professor Nelson wrote: No "mainstream judge is interested solely in the literal definitions of a statute's words." Nelson, What Is Textualism?, 91 Va. L. Rev. 347 , 376 (2005). The ordinary meaning that counts is the ordinary public meaning at the time of enactment-although in this case, that temporal principle matters little because the ordinary meaning of "discriminate because of sex" was the same in 1964 as it is now.

 Judges adhere to ordinary meaning for two main reasons: rule of law and democratic accountability. A society governed by the rule of law must have laws that are known and understandable to the citizenry. And judicial adherence to ordinary meaning facilitates the democratic accountability of America's elected representatives for the laws they enact. Citizens and legislators must be able to ascertain the law by reading the words of the statute. Both the rule of law and democratic accountability badly suffer when a court adopts a hidden or obscure interpretation of the law, and not its ordinary meaning.

 Consider a simple example of how ordinary meaning differs from literal meaning. A statutory ban on "vehicles in the park" would literally encompass a baby stroller. But no good judge would interpret the statute that way because the word "vehicle," in its ordinary meaning, does not encompass baby strollers.

 The ordinary meaning principle is longstanding and well settled. Time and again, this Court has rejected literalism in favor of ordinary meaning. Take a few examples:

 The Court recognized that beans may be seeds "in the language of botany or natural history," but concluded that beans are not seeds "in commerce" or "in common parlance." Robertson v. Salomon , 130 U.S. 412 , 414, 9 S.Ct. 559 , 32 L.Ed. 995 (1889).

 The Court explained that tomatoes are literally "the fruit of a vine," but "in the common language of the people," tomatoes are vegetables. Nix v. Hedden , 149 U.S. 304 , 307, 13 S.Ct. 881 , 37 L.Ed. 745 (1893).

 The Court stated that the statutory term "vehicle" does not cover an aircraft: "No doubt etymologically it is possible to use the word to signify a conveyance working *1826 on land, water or air .... But in everyday speech 'vehicle' calls up the picture of a thing moving on land." McBoyle v. United States , 283 U.S. 25 , 26, 51 S.Ct. 340 , 75 L.Ed. 816 (1931).

 The Court pointed out that "this Court's interpretation of the three-judge-court statutes has frequently deviated from the path of literalism." Gonzalez v. Automatic Employees Credit Union , 419 U.S. 90 , 96, 95 S.Ct. 289 , 42 L.Ed.2d 249 (1974).

 The Court refused a reading of "mineral deposits" that would include water, even if "water is a 'mineral,' in the broadest sense of that word," because it would bring about a "major ... alteration in established legal relationships based on nothing more than an overly literal reading of a statute, without any regard for its context or history." Andrus v. Charlestone Stone Products Co. , 436 U.S. 604 , 610, 616, 98 S.Ct. 2002 , 56 L.Ed.2d 570 (1978).

 The Court declined to interpret "facilitating" a drug distribution crime in a way that would cover purchasing drugs, because the "literal sweep of 'facilitate' sits uncomfortably with common usage." Abuelhawa v. United States , 556 U.S. 816 , 820, 129 S.Ct. 2102 , 173 L.Ed.2d 982 (2009).

 The Court rebuffed a literal reading of "personnel rules" that would encompass any rules that personnel must follow (as opposed to human resources rules about personnel), and stated that no one "using ordinary language would describe" personnel rules "in this manner." Milner v. Department of Navy , 562 U.S. 562 , 578, 131 S.Ct. 1259 , 179 L.Ed.2d 268 (2011).

 The Court explained that, when construing statutory phrases such as "arising from," it avoids "uncritical literalism leading to results that no sensible person could have intended." Jennings v. Rodriguez , 583 U.S. ----, ---- - ----, 138 S.Ct. 830 , 840, 200 L.Ed.2d 122 (2018) (plurality opinion) (internal quotation marks omitted).

 Those cases exemplify a deeply rooted principle: When there is a divide between the literal meaning and the ordinary meaning, courts must follow the ordinary meaning.

 Next is a critical point of emphasis in this case. The difference between literal and ordinary meaning becomes especially important when-as in this case-judges consider phrases in statutes. (Recall that the shorthand version of the phrase at issue here is "discriminate because of sex.") 3 Courts must heed the ordinary meaning of the phrase as a whole , not just the meaning of the words in the phrase. That is because a phrase may have a more precise or confined meaning than the literal meaning of the individual words in the phrase. Examples abound. An "American flag" could literally encompass a flag made in America, but in common parlance it denotes the Stars and Stripes. A "three-pointer" could literally include a field goal in football, but in common parlance, it is a shot from behind the arc in basketball. A "cold war" could literally mean any wintertime war, but in common parlance it signifies a conflict short of open warfare. A "washing machine" could literally refer to any machine used for washing any item, but in everyday speech it means a machine for washing clothes.

 This Court has often emphasized the importance of sticking to the ordinary meaning of a phrase , rather than the *1827 meaning of words in the phrase. In FCC v. AT&T Inc. , 562 U.S. 397 , 131 S.Ct. 1177 , 179 L.Ed.2d 132 (2011), for example, the Court explained:

 "AT&T's argument treats the term 'personal privacy' as simply the sum of its two words: the privacy of a person.... But two words together may assume a more particular meaning than those words in isolation. We understand a golden cup to be a cup made of or resembling gold. A golden boy, on the other hand, is one who is charming, lucky, and talented. A golden opportunity is one not to be missed. 'Personal' in the phrase 'personal privacy' conveys more than just 'of a person.' It suggests a type of privacy evocative of human concerns-not the sort usually associated with an entity like, say, AT&T." Id., at 406 , 131 S.Ct. 1177 .
 Exactly right and exactly on point in this case.

 Justice Scalia explained the extraordinary importance of hewing to the ordinary meaning of a phrase: "Adhering to the fair meaning of the text (the textualist's touchstone) does not limit one to the hyperliteral meaning of each word in the text. In the words of Learned Hand: 'a sterile literalism ... loses sight of the forest for the trees.' The full body of a text contains implications that can alter the literal meaning of individual words." A. Scalia & B. Garner, Reading Law 356 (2012) (footnote omitted). Put another way, "the meaning of a sentence may be more than that of the separate words, as a melody is more than the notes." Helvering v. Gregory , 69 F.2d 809 , 810-811 (CA2 1934) (L. Hand, J.). Judges must take care to follow ordinary meaning "when two words combine to produce a meaning that is not the mechanical composition of the two words separately." Eskridge, Interpreting Law, at 62. Dictionaries are not "always useful for determining the ordinary meaning of word clusters (like 'driving a vehicle') or phrases and clauses or entire sentences." Id. , at 44. And we must recognize that a phrase can cover a "dramatically smaller category than either component term." Id., at 62.

 If the usual evidence indicates that a statutory phrase bears an ordinary meaning different from the literal strung-together definitions of the individual words in the phrase, we may not ignore or gloss over that discrepancy. "Legislation cannot sensibly be interpreted by stringing together dictionary synonyms of each word and proclaiming that, if the right example of the meaning of each is selected, the 'plain meaning' of the statute leads to a particular result. No theory of interpretation, including textualism itself, is premised on such an approach." 883 F.3d 100 , 144, n. 7 (CA2 2018) (Lynch, J., dissenting). 4

 In other words, this Court's precedents and longstanding principles of statutory interpretation teach a clear lesson: Do not simply split statutory phrases into their component words, look up each in a dictionary, and then mechanically put them together again, as the majority opinion today mistakenly does. See ante , at 1756 - 1759. To reiterate Justice Scalia's caution, that approach misses the forest for the trees.

 *1828 A literalist approach to interpreting phrases disrespects ordinary meaning and deprives the citizenry of fair notice of what the law is. It destabilizes the rule of law and thwarts democratic accountability. For phrases as well as terms, the "linchpin of statutory interpretation is ordinary meaning , for that is going to be most accessible to the citizenry desirous of following the law and to the legislators and their staffs drafting the legal terms of the plans launched by statutes and to the administrators and judges implementing the statutory plan." Eskridge, Interpreting Law, at 81; see Scalia, A Matter of Interpretation, at 17.

 Bottom line: Statutory Interpretation 101 instructs courts to follow ordinary meaning, not literal meaning, and to adhere to the ordinary meaning of phrases, not just the meaning of the words in a phrase.

 Second , in light of the bedrock principle that we must adhere to the ordinary meaning of a phrase, the question in this case boils down to the ordinary meaning of the phrase "discriminate because of sex." Does the ordinary meaning of that phrase encompass discrimination because of sexual orientation? The answer is plainly no.

 On occasion, it can be difficult for judges to assess ordinary meaning. Not here. Both common parlance and common legal usage treat sex discrimination and sexual orientation discrimination as two distinct categories of discrimination-back in 1964 and still today.

 As to common parlance, few in 1964 (or today) would describe a firing because of sexual orientation as a firing because of sex. As commonly understood, sexual orientation discrimination is distinct from, and not a form of, sex discrimination. The majority opinion acknowledges the common understanding, noting that the plaintiffs here probably did not tell their friends that they were fired because of their sex. Ante , at 1762 - 1763. That observation is clearly correct. In common parlance, Bostock and Zarda were fired because they were gay, not because they were men.

 Contrary to the majority opinion's approach today, this Court has repeatedly emphasized that common parlance matters in assessing the ordinary meaning of a statute, because courts heed how "most people" "would have understood" the text of a statute when enacted. New Prime Inc. v. Oliveira , 586 U.S. ----, ---- - ----, 139 S.Ct. 532 , 538-539, 202 L.Ed.2d 536 (2019) ; see Henson v. Santander Consumer USA Inc. , 582 U.S. ----, ----, 137 S.Ct. 1718 , 1722, 198 L.Ed.2d 177 (2017) (using a conversation between friends to demonstrate ordinary meaning); see also Wisconsin Central Ltd. v. United States , 585 U.S. ----, ---- - ----, 138 S.Ct. 2067 , 2070-2071, 201 L.Ed.2d 490 (2018) (similar); AT&T , 562 U.S. at 403-404 , 131 S.Ct. 1177 (similar).

 Consider the employer who has four employees but must fire two of them for financial reasons. Suppose the four employees are a straight man, a straight woman, a gay man, and a lesbian. The employer with animosity against women (animosity based on sex) will fire the two women. The employer with animosity against gays (animosity based on sexual orientation) will fire the gay man and the lesbian. Those are two distinct harms caused by two distinct biases that have two different outcomes. To treat one as a form of the other-as the majority opinion does-misapprehends common language, human psychology, and real life. See Hively v. Ivy Tech Community College of Ind. , 853 F.3d 339 , 363 (CA7 2017) (Sykes, J., dissenting).

 It also rewrites history. Seneca Falls was not Stonewall. The women's rights *1829 movement was not (and is not) the gay rights movement, although many people obviously support or participate in both. So to think that sexual orientation discrimination is just a form of sex discrimination is not just a mistake of language and psychology, but also a mistake of history and sociology.

 Importantly, an overwhelming body of federal law reflects and reinforces the ordinary meaning and demonstrates that sexual orientation discrimination is distinct from, and not a form of, sex discrimination. Since enacting Title VII in 1964, Congress has never treated sexual orientation discrimination the same as, or as a form of, sex discrimination. Instead, Congress has consistently treated sex discrimination and sexual orientation discrimination as legally distinct categories of discrimination.

 Many federal statutes prohibit sex discrimination, and many federal statutes also prohibit sexual orientation discrimination. But those sexual orientation statutes expressly prohibit sexual orientation discrimination in addition to expressly prohibiting sex discrimination. Every single one. To this day, Congress has never defined sex discrimination to encompass sexual orientation discrimination. Instead, when Congress wants to prohibit sexual orientation discrimination in addition to sex discrimination, Congress explicitly refers to sexual orientation discrimination. 5

 That longstanding and widespread congressional practice matters. When interpreting statutes, as the Court has often said, we "usually presume differences in language" convey "differences in meaning." Wisconsin Central , 585 U.S., at ----, 138 S.Ct., at 2071 (internal quotation marks omitted). When Congress chooses distinct phrases to accomplish distinct purposes, and does so over and over again for decades, we may not lightly toss aside all of Congress's careful handiwork. As Justice Scalia explained for the Court, "it is not our function" to "treat alike subjects that different Congresses have chosen to treat differently." West Virginia Univ. Hospitals, Inc. v. Casey , 499 U.S. 83 , 101, 111 S.Ct. 1138 , 113 L.Ed.2d 68 (1991) ; see id., at 92 , 111 S.Ct. 1138 .

 And the Court has likewise stressed that we may not read "a specific concept into general words when precise language in other statutes reveals that Congress knew how to identify that concept." Eskridge, Interpreting Law, at 415; see University of Tex. Southwestern Medical Center v. Nassar , 570 U.S. 338 , 357, 133 S.Ct. 2517 , 186 L.Ed.2d 503 (2013) ; Arlington Central School Dist. Bd. of Ed. v. Murphy , 548 U.S. 291 , 297-298, 126 S.Ct. 2455 , 165 L.Ed.2d 526 (2006) ;

 *1830 Jama v. Immigration and Customs Enforcement , 543 U.S. 335 , 341-342, 125 S.Ct. 694 , 160 L.Ed.2d 708 (2005) ; Custis v. United States , 511 U.S. 485 , 491-493, 114 S.Ct. 1732 , 128 L.Ed.2d 517 (1994) ; West Virginia Univ. Hospitals , 499 U.S. at 99 , 111 S.Ct. 1138 .

 So it is here. As demonstrated by all of the statutes covering sexual orientation discrimination, Congress knows how to prohibit sexual orientation discrimination. So courts should not read that specific concept into the general words "discriminate because of sex." We cannot close our eyes to the indisputable fact that Congress-for several decades in a large number of statutes-has identified sex discrimination and sexual orientation discrimination as two distinct categories.

 Where possible, we also strive to interpret statutes so as not to create undue surplusage. It is not uncommon to find some scattered redundancies in statutes. But reading sex discrimination to encompass sexual orientation discrimination would cast aside as surplusage the numerous references to sexual orientation discrimination sprinkled throughout the U.S. Code in laws enacted over the last 25 years.

 In short, an extensive body of federal law both reflects and reinforces the widespread understanding that sexual orientation discrimination is distinct from, and not a form of, sex discrimination.

 The story is the same with bills proposed in Congress. Since the 1970s, Members of Congress have introduced many bills to prohibit sexual orientation discrimination in the workplace. Until very recently, all of those bills would have expressly established sexual orientation as a separately proscribed category of discrimination. The bills did not define sex discrimination to encompass sexual orientation discrimination. 6

 The proposed bills are telling not because they are relevant to congressional intent regarding Title VII. See Central Bank of Denver, N.A. v. First Interstate Bank of Denver, N.A. , 511 U.S. 164 , 186-188, 114 S.Ct. 1439 , 128 L.Ed.2d 119 (1994). Rather, the proposed bills are telling because they, like the enacted laws, further demonstrate the widespread usage of the English language in the United States: Sexual orientation discrimination is distinct from, and not a form of, sex discrimination.

 *1831 Presidential Executive Orders reflect that same common understanding. In 1967, President Johnson signed an Executive Order prohibiting sex discrimination in federal employment. In 1969, President Nixon issued a new order that did the same. Exec. Order No. 11375, 3 CFR 684 (1966-1970 Comp.); Exec. Order No. 11478, id., at 803. In 1998, President Clinton charted a new path and signed an Executive Order prohibiting sexual orientation discrimination in federal employment. Exec. Order No. 13087, 3 CFR 191 (1999). The Nixon and Clinton Executive Orders remain in effect today.

 Like the relevant federal statutes, the 1998 Clinton Executive Order expressly added sexual orientation as a new, separately prohibited form of discrimination. As Judge Lynch cogently spelled out, "the Clinton Administration did not argue that the prohibition of sex discrimination in" the prior 1969 Executive Order "already banned, or henceforth would be deemed to ban, sexual orientation discrimination." 883 F.3d at 152, n. 22 (dissenting opinion). In short, President Clinton's 1998 Executive Order indicates that the Executive Branch, like Congress, has long understood sexual orientation discrimination to be distinct from, and not a form of, sex discrimination.

 Federal regulations likewise reflect that same understanding. The Office of Personnel Management is the federal agency that administers and enforces personnel rules across the Federal Government. OPM has issued regulations that "govern ... the employment practices of the Federal Government generally, and of individual agencies." 5 CFR §§ 300.101 , 300.102 (2019). Like the federal statutes and the Presidential Executive Orders, those OPM regulations separately prohibit sex discrimination and sexual orientation discrimination.

 The States have proceeded in the same fashion. A majority of States prohibit sexual orientation discrimination in employment, either by legislation applying to most workers, 7 an executive order applying *1832 to public employees, 8 or both. Almost every state statute or executive order proscribing sexual orientation discrimination expressly prohibits sexual orientation discrimination separately from the State's ban on sex discrimination.

 That common usage in the States underscores that sexual orientation discrimination is commonly understood as a legal concept distinct from sex discrimination.

 And it is the common understanding in this Court as well. Since 1971, the Court has employed rigorous or heightened constitutional scrutiny of laws that classify on the basis of sex. See United States v. Virginia , 518 U.S. 515 , 531-533, 116 S.Ct. 2264 , 135 L.Ed.2d 735 (1996) ; J. E. B. v. Alabama ex rel. T. B. , 511 U.S. 127 , 136-137, 114 S.Ct. 1419 , 128 L.Ed.2d 89 (1994) ; Craig v. Boren , 429 U.S. 190 , 197-199, 97 S.Ct. 451 , 50 L.Ed.2d 397 (1976) ; Frontiero v. Richardson , 411 U.S. 677 , 682-684, 93 S.Ct. 1764 , 36 L.Ed.2d 583 (1973) (plurality opinion); Reed v. Reed , 404 U.S. 71 , 75-77, 92 S.Ct. 251 , 30 L.Ed.2d 225 (1971). Over the last several decades, the Court has also decided many cases involving sexual orientation. But in those cases, the Court never suggested that sexual orientation discrimination is just a form of sex discrimination.

 *1833 All of the Court's cases from Bowers to Romer to Lawrence to Windsor to Obergefell would have been far easier to analyze and decide if sexual orientation discrimination were just a form of sex discrimination and therefore received the same heightened scrutiny as sex discrimination under the Equal Protection Clause. See Bowers v. Hardwick , 478 U.S. 186 , 106 S.Ct. 2841 , 92 L.Ed.2d 140 (1986) ; Romer v. Evans , 517 U.S. 620 , 116 S.Ct. 1620 , 134 L.Ed.2d 855 (1996) ; Lawrence v. Texas , 539 U.S. 558 , 123 S.Ct. 2472 , 156 L.Ed.2d 508 (2003) ; United States v. Windsor , 570 U.S. 744 , 133 S.Ct. 2675 , 186 L.Ed.2d 808 (2013) ; Obergefell v. Hodges , 576 U.S. 644 , 135 S.Ct. 2584 , 192 L.Ed.2d 609 (2015).

 Did the Court in all of those sexual orientation cases just miss that obvious answer-and overlook the fact that sexual orientation discrimination is actually a form of sex discrimination? That seems implausible. Nineteen Justices have participated in those cases. Not a single Justice stated or even hinted that sexual orientation discrimination was just a form of sex discrimination and therefore entitled to the same heightened scrutiny under the Equal Protection Clause. The opinions in those five cases contain no trace of such reasoning. That is presumably because everyone on this Court, too, has long understood that sexual orientation discrimination is distinct from, and not a form of, sex discrimination.

 In sum, all of the usual indicators of ordinary meaning-common parlance, common usage by Congress, the practice in the Executive Branch, the laws in the States, and the decisions of this Court-overwhelmingly establish that sexual orientation discrimination is distinct from, and not a form of, sex discrimination. The usage has been consistent across decades, in both the federal and state contexts.

 Judge Sykes summarized the law and language this way: "To a fluent speaker of the English language-then and now-... discrimination 'because of sex' is not reasonably understood to include discrimination based on sexual orientation, a different immutable characteristic. Classifying people by sexual orientation is different than classifying them by sex. The two traits are categorically distinct and widely recognized as such. There is no ambiguity or vagueness here." Hively , 853 F.3d at 363 (dissenting opinion).

 To tie it all together, the plaintiffs have only two routes to succeed here. Either they can say that literal meaning overrides ordinary meaning when the two conflict. Or they can say that the ordinary meaning of the phrase "discriminate because of sex" encompasses sexual orientation discrimination. But the first flouts long-settled principles of statutory interpretation. And the second contradicts the widespread ordinary use of the English language in America.

 II

 Until the last few years, every U.S. Court of Appeals to address this question concluded that Title VII does not prohibit discrimination because of sexual orientation. As noted above, in the first 10 Courts of Appeals to consider the issue, all 30 federal judges agreed that Title VII does not prohibit sexual orientation discrimination. 30 out of 30 judges. 9

 *1834 The unanimity of those 30 federal judges shows that the question as a matter of law, as compared to as a matter of policy, was not deemed close. Those 30 judges realized a seemingly obvious point: Title VII is not a general grant of authority for judges to fashion an evolving common law of equal treatment in the workplace. Rather, Title VII identifies certain specific categories of prohibited discrimination. And under the separation of powers, Congress-not the courts-possesses the authority to amend or update the law, as Congress has done with age discrimination and disability discrimination, for example.

 So what changed from the situation only a few years ago when 30 out of 30 federal judges had agreed on this question? Not the text of Title VII. The law has not changed. Rather, the judges' decisions have evolved.

 To be sure, the majority opinion today does not openly profess that it is judicially updating or amending Title VII. Cf. Hively , 853 F.3d at 357 (Posner, J., concurring). But the majority opinion achieves the same outcome by seizing on literal meaning and overlooking the ordinary meaning of the phrase "discriminate because of sex." Although the majority opinion acknowledges that the meaning of a phrase and the meaning of a phrase's individual words could differ, it dismisses phrasal meaning for purposes of this case. The majority opinion repeatedly seizes on the meaning of the statute's individual terms, mechanically puts them back together, and generates an interpretation of the phrase "discriminate because of sex" that is literal. See ante , at 1756 - 1759, 1763, 1766 - 1768. But to reiterate, that approach to statutory interpretation is fundamentally flawed. Bedrock principles of statutory interpretation dictate that we look to ordinary meaning, not literal meaning, and that we likewise adhere to the ordinary meaning of phrases, not just the meaning of words in a phrase. And the ordinary meaning of the phrase "discriminate because of sex" does not encompass sexual orientation discrimination.

 The majority opinion deflects that critique by saying that courts should base their interpretation of statutes on the text as written, not on the legislators' subjective intentions. Ante , at 1764 - 1765, 1766 - 1770. Of course that is true. No one disagrees. It is "the provisions of our laws rather than the principal concerns of our legislators by which we are governed." Oncale v. Sundowner Offshore Services, Inc. , 523 U.S. 75 , 79, 118 S.Ct. 998 , 140 L.Ed.2d 201 (1998).

 But in my respectful view, the majority opinion makes a fundamental mistake by confusing ordinary meaning with subjective intentions. To briefly explain: In the early years after Title VII was enacted, some may have wondered whether Title VII's prohibition on sex discrimination protected male employees. After all, covering male employees may not have been the intent of some who voted for the statute. Nonetheless, discrimination on the basis of sex against women and discrimination on the basis of sex against men are both understood as discrimination because of sex (back in 1964 and now) and are therefore encompassed within Title VII. Cf. id., at 78-79 , 118 S.Ct. 998 ; see Newport News Shipbuilding & Dry Dock Co. v. EEOC , 462 U.S. 669 , 682-685, 103 S.Ct. 2622 , 77 L.Ed.2d 89 (1983). So too, regardless of what the intentions of the drafters might *1835 have been, the ordinary meaning of the law demonstrates that harassing an employee because of her sex is discriminating against the employee because of her sex with respect to the "terms, conditions, or privileges of employment," as this Court rightly concluded. Meritor Savings Bank, FSB v. Vinson , 477 U.S. 57 , 64, 106 S.Ct. 2399 , 91 L.Ed.2d 49 (1986) (internal quotation marks omitted). 10

 By contrast, this case involves sexual orientation discrimination, which has long and widely been understood as distinct from, and not a form of, sex discrimination. Until now, federal law has always reflected that common usage and recognized that distinction between sex discrimination and sexual orientation discrimination. To fire one employee because she is a woman and another employee because he is gay implicates two distinct societal concerns, reveals two distinct biases, imposes two distinct harms, and falls within two distinct statutory prohibitions.

 To be sure, as Judge Lynch appropriately recognized, it is "understandable" that those seeking legal protection for gay people "search for innovative arguments to classify workplace bias against gays as a form of discrimination that is already prohibited by federal law. But the arguments advanced by the majority ignore the evident meaning of the language of Title VII, the social realities that distinguish between the kinds of biases that the statute sought to exclude from the workplace from those it did not, and the distinctive nature of anti-gay prejudice." 883 F.3d at 162 (dissenting opinion).

 The majority opinion insists that it is not rewriting or updating Title VII, but instead is just humbly reading the text of the statute as written. But that assertion is tough to accept. Most everyone familiar with the use of the English language in America understands that the ordinary meaning of sexual orientation discrimination is distinct from the ordinary meaning of sex discrimination. Federal law distinguishes the two. State law distinguishes the two. This Court's cases distinguish the two. Statistics on discrimination distinguish the two. History distinguishes the two. Psychology distinguishes the two. Sociology distinguishes the two. Human resources departments all over America distinguish the two. Sports leagues distinguish the two. Political groups distinguish *1836 the two. Advocacy groups distinguish the two. Common parlance distinguishes the two. Common sense distinguishes the two.

 As a result, many Americans will not buy the novel interpretation unearthed and advanced by the Court today. Many will no doubt believe that the Court has unilaterally rewritten American vocabulary and American law-a "statutory amendment courtesy of unelected judges." Hively , 853 F.3d at 360 (Sykes, J., dissenting). Some will surmise that the Court succumbed to "the natural desire that beguiles judges along with other human beings into imposing their own views of goodness, truth, and justice upon others." Furman v. Georgia , 408 U.S. 238 , 467, 92 S.Ct. 2726 , 33 L.Ed.2d 346 (1972) (Rehnquist, J., dissenting).

 I have the greatest, and unyielding, respect for my colleagues and for their good faith. But when this Court usurps the role of Congress, as it does today, the public understandably becomes confused about who the policymakers really are in our system of separated powers, and inevitably becomes cynical about the oft-repeated aspiration that judges base their decisions on law rather than on personal preference. The best way for judges to demonstrate that we are deciding cases based on the ordinary meaning of the law is to walk the walk, even in the hard cases when we might prefer a different policy outcome.

 * * *

 In judicially rewriting Title VII, the Court today cashiers an ongoing legislative process, at a time when a new law to prohibit sexual orientation discrimination was probably close at hand. After all, even back in 2007-a veritable lifetime ago in American attitudes about sexual orientation-the House voted 235 to 184 to prohibit sexual orientation discrimination in employment. H.R. 3685, 110th Cong., 1st Sess. In 2013, the Senate overwhelmingly approved a similar bill, 64 to 32. S. 815, 113th Cong., 1st Sess. In 2019, the House voted 236 to 173 to amend Title VII to prohibit employment discrimination on the basis of sexual orientation. H.R. 5, 116th Cong., 1st Sess. It was therefore easy to envision a day, likely just in the next few years, when the House and Senate took historic votes on a bill that would prohibit employment discrimination on the basis of sexual orientation. It was easy to picture a massive and celebratory Presidential signing ceremony in the East Room or on the South Lawn.

 It is true that meaningful legislative action takes time-often too much time, especially in the unwieldy morass on Capitol Hill. But the Constitution does not put the Legislative Branch in the "position of a television quiz show contestant so that when a given period of time has elapsed and a problem remains unsolved by them, the federal judiciary may press a buzzer and take its turn at fashioning a solution." Rehnquist, The Notion of a Living Constitution, 54 Texas L. Rev. 693 , 700 (1976). The proper role of the Judiciary in statutory interpretation cases is "to apply, not amend, the work of the People's representatives," even when the judges might think that "Congress should reenter the field and alter the judgments it made in the past." Henson , 582 U.S., at ---- - ----, 137 S.Ct., at 1725 .

 Instead of a hard-earned victory won through the democratic process, today's victory is brought about by judicial dictate-judges latching on to a novel form of living literalism to rewrite ordinary meaning and remake American law. Under the Constitution and laws of the United States, this Court is the wrong body to change American law in that way. The Court's ruling "comes at a great cost to representative self-government." Hively , 853 F.3d at 360 (Sykes, J., dissenting). And the implications of this Court's usurpation of *1837 the legislative process will likely reverberate in unpredictable ways for years to come.

 Notwithstanding my concern about the Court's transgression of the Constitution's separation of powers, it is appropriate to acknowledge the important victory achieved today by gay and lesbian Americans. Millions of gay and lesbian Americans have worked hard for many decades to achieve equal treatment in fact and in law. They have exhibited extraordinary vision, tenacity, and grit-battling often steep odds in the legislative and judicial arenas, not to mention in their daily lives. They have advanced powerful policy arguments and can take pride in today's result. Under the Constitution's separation of powers, however, I believe that it was Congress's role, not this Court's, to amend Title VII. I therefore must respectfully dissent from the Court's judgment.

 Although this opinion does not separately analyze discrimination on the basis of gender identity, this opinion's legal analysis of discrimination on the basis of sexual orientation would apply in much the same way to discrimination on the basis of gender identity.

 In full, the statute provides:

 " It shall be an unlawful employment practice for an employer -

 "(1) to fail or refuse to hire or to discharge any individual, or otherwise to discriminate against any individual with respect to his compensation, terms, conditions, or privileges of employment, because of such individual's race, color, religion, sex, or national origin ; or

 "(2) to limit, segregate, or classify his employees or applicants for employment in any way which would deprive or tend to deprive any individual of employment opportunities or otherwise adversely affect his status as an employee, because of such individual's race, color, religion, sex, or national origin." 42 U.S.C. § 2000e-2(a) (emphasis added).

 As the Court today recognizes, Title VII contains an important exemption for religious organizations. § 2000e-1(a) ; see also § 2000e-2(e). The First Amendment also safeguards the employment decisions of religious employers. See Hosanna-Tabor Evangelical Lutheran Church and School v. EEOC , 565 U.S. 171 , 188-195, 132 S.Ct. 694 , 181 L.Ed.2d 650 (2012). So too, the Religious Freedom Restoration Act of 1993 exempts employers from federal laws that substantially burden the exercise of religion, subject to limited exceptions. § 2000bb-1.

 The full phrasing of the statute is provided above in footnote 2. This opinion uses "discriminate because of sex" as shorthand for "discriminate ... because of ... sex." Also, the plaintiffs do not dispute that the ordinary meaning of the statutory phrase "discriminate" because of sex is the same as the statutory phrase "to fail or refuse to hire or to discharge any individual" because of sex.

 Another longstanding canon of statutory interpretation-the absurdity canon-similarly reflects the law's focus on ordinary meaning rather than literal meaning. That canon tells courts to avoid construing a statute in a way that would lead to absurd consequences. The absurdity canon, properly understood, is "an implementation of (rather than ... an exception to) the ordinary meaning rule." W. Eskridge, Interpreting Law 72 (2016). "What the rule of absurdity seeks to do is what all rules of interpretation seek to do: make sense of the text." A. Scalia & B. Garner, Reading Law 235 (2012).

 See 18 U.S.C. § 249 (a)(2)(A) (criminalizing violence because of "gender, sexual orientation"); 20 U.S.C. § 1092 (f)(1)(F)(ii) (requiring funding recipients to collect statistics on crimes motivated by the victim's "gender, ... sexual orientation"); 34 U.S.C. § 12291 (b)(13)(A) (prohibiting discrimination on the basis of "sex, ... sexual orientation"); § 30501(1) (identifying violence motivated by "gender, sexual orientation" as national problem); § 30503(a)(1)(C) (authorizing Attorney General to assist state, local, and tribal investigations of crimes motivated by the victim's "gender, sexual orientation"); §§ 41305(b)(1), (3) (requiring Attorney General to acquire data on crimes motivated by "gender ..., sexual orientation," but disclaiming any cause of action including one "based on discrimination due to sexual orientation"); 42 U.S.C. § 294e-1(b)(2) (conditioning funding on institution's inclusion of persons of "different genders and sexual orientations"); see also United States Sentencing Commission, Guidelines Manual § 3A1.1(a) (Nov. 2018) (authorizing increased offense level if the crime was motivated by the victim's "gender ... or sexual orientation"); 2E Guide to Judiciary Policy § 320 (2019) (prohibiting judicial discrimination because of "sex, ... sexual orientation").

'affectional or sexual preference,' " defined as "having or manifesting an emotional or physical attachment to another consenting person or persons of either gender, or having or manifesting a preference for such attachment"); S. 1708, 97th Cong., 1st Sess., §§ 1, 2 (1981) ("inserting after 'sex' ...

 An amicus brief supporting the plaintiffs suggests that the plaintiffs' interpretive approach is supported by the interpretive approach employed by the Court in its landmark decision in Brown v. Board of Education , 347 U.S. 483 , 74 S.Ct. 686 , 98 L.Ed. 873 (1954). See Brief for Anti-Discrimination Scholars as Amici Curiae 4. That suggestion is incorrect. Brown is a correct decision as a matter of original public meaning. There were two analytical components of Brown . One issue was the meaning of "equal protection." The Court determined that black Americans-like all Americans-have an individual equal protection right against state discrimination on the basis of race. (That point is also directly made in Bolling v. Sharpe , 347 U.S. 497 , 499-500, 74 S.Ct. 693 , 98 L.Ed. 884 (1954).) Separate but equal is not equal. The other issue was whether that racial nondiscrimination principle applied to public schools, even though public schools did not exist in any comparable form in 1868. The answer was yes. The Court applied the equal protection principle to public schools in the same way that the Court applies, for example, the First Amendment to the Internet and the Fourth Amendment to cars.

 This case raises the same kind of inquiry as the first question in Brown . There, the question was what equal protection meant. Here, the question is what "discriminate because of sex" means. If this case raised the question whether the sex discrimination principle in Title VII applied to some category of employers unknown in 1964, such as to social media companies, it might be a case in Brown 's second category, akin to the question whether the racial nondiscrimination principle applied to public schools. But that is not this case.
