I don't think it's people worried about this as much as people feeling it comes off as being forced.
Heck, anytime I mention boy clothes or girl clothes around my 7 year old daughter she parrots what teachers tell her "there's no such thing as BOY or GIRL clothes"
All I can think to myself is "why aren't they just teaching you math, reading, science etc? What's this forced stuff? They won't teach you about the injustices of history but they'll tell ya son he can put on a dress. GO FIGURE.
End rant Coli.
Couldn't have said it better myself

all over.
I would snatch my children out of that school quick
