This is nothing more than the thought police grasping at straws trying to project an aura of legitimacy.
People say nasty things to each other. Nobody is more nasty to each other than young women. That is a fact. And, if I had a nickel for every time I overheard a nasty conversation between females at the water cooler about some man, I'd be pretty darn wealthy.
So, let us stop lying to ourselves by saying that gender hostility is a one-way street, shall we? People are people, and people will always say nasty things to each other. The thought police need to get over themselves and learn that the ability to deal with adversity and hostility internally is necessary for survival.
