Such a bullshit argument. "no you see, it's ok to be a bigot because of the context!" Such crap - it really sickens me to see people arguing in favor of bigotry and hate because they feel they can get away with it.
Welcome to feminism. Unfortunately, the only group which is actually trying to solve sexism through ending gender-based treatment and stereotypes is (a faction of) the Men's Rights movement, and they're a cesspit. We're all fucked :-(
