Changing the definition of “sex” to mean “gender identity” in federal law has widespread consequences. For one, it would require employers to treat men who perceive themselves to be women as if they are, in fact, women – unless those employees don’t “meet the expectations” of what women “[t]ypically” look like. This is an impossible standard that would force employers to engage in the very stereotypes the law is supposed to prohibit.

Beyond that, changing the meaning of “sex” would greatly impact women and girls. It would allow for women’s scholarships to be given to men who perceive themselves to be women. It would force girls to compete in sports against boys who identify as girls, which denies them a level playing field. And it would force organizations to open women’s shelters, locker rooms, restrooms, and showers to men who perceive themselves to be women."
