The goalposts for "sexism" have moved to the edge of the galaxy if people today think that's sexism.

Parent says that "identity is socially-constructed", they defend trans people, they say it "isn't any less justifiable than being assigned good ol' football-playin', roughhousin', English class-hatin', red-blooded American manhood"

- but the fact they said "presenting" as opposed to "being" a woman is sexism, as if they're some "chauvinist pig"?

That's why we can't have nice things...
