Stuff like this is really bothersome. Another example is when a woman is clearly being a misogynist, but thinks that's impossible because she's a woman too. The worst and most sexist things I've ever heard were from white professional women who think the rules don't apply to them, epsecially if they are discussing younger more attractive women or poorer, less educated women. And in the workplace no less!
I think we live in an absurd level of PC pressure and I think that partly explains why guys like Trump are doing so well in the polls. People are just sick of navigating this stuff and its all fairly arbitrary. Ignoring this isn't doing anyone any good, especially the Democrats who keep losing elections. Not sure what the solution here is, but I hope the pendulum is beginning to swing the other way. The fact that 'mansplaining' is in the iphone dictionary is especially odious. Its a straight up slur. Being a tonedeaf know-it-all knows no gender.
