It's a serious thing, yeah. Women who work to displace, or hinder other women as a class, disgust me. See: any pro life female politician. And yeah, it's always fun to see the excuse of "I don't think you know what you are saying, cause this woman disagrees, and she's a woman, and she says there's no sexism" (also "this guy is black and he says there is no racism". In fact one of the single most successful use of the "this guy is X and he says.." was in the gay marriage issues. The right found gay men who didn't think gay men should be married, cause gay men were - i dn't know, "different" "above that", "beyond traditional lables' etc. and so they could not only say "gays are bad" but also "and even gays don't want gay marriage, so why are we doing it".
Black police officers tend to be far more racist towards Blacks then White officers, at least in places that aren't overtly racist. It has to do with people not being aware of self prejudice. It's even worse with misogynistic women who are even aware of the fact that they can be self prejudicial and yet they're ****ing arrogant about it. I really hate the misogynistic women who come up with examples of brainwashed women giving birth after violent rape and use it as an excuse to force that on all women.
"Denying women the vote isn't sexist, because some women said so!" (True story.)
Or pointing to people like Malcom X who wanted Blacks to separate as evidence for segregation because "Blacks don't really want to integrate."
I doubt the cop thing is self prejudice as much as needing to fight the prejudice in the line, so they work double hard to "fit in". "Yes, of ocurse i can do my job and arrest black people even if i'm black" etc.
And the use of "she is an X, and if she said it, it must be true" is part of the world of privlidge. using other people to make your point.
