You're drawing a distinction without difference. You can phrase basically any rule that discriminates against a subgroup as a rule on the larger group that only affects the subgroup. For example, I don't think anyone would say, "It isn't discrimination against women to forbid all people from doing something without a Y chromosome." The fact that the phrasing doesn't say "women" doesn't make it not discrimination, because it specifically targets attributes of women.
