12 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. . That observation is clearly correct. In common parlance, Bostock and Zarda were fired because they were gay, not because they were men.

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
