I was baited into an argument with a social justicite the other night, and I wish I'd kept screencaps of the thing. A Frozen thread on /co/ degenerated into the usual "Wah feminists" whining that pops up every time a show has a female main character. About halfway in, a person who's basically spent the thread denouncing everything ever done by whites, males, or heterosexuals as sexist/racist/what have you declares that "White male gaming culture is the most sexist culture there is."
That's where I stepped in. I agreed that gaming culture can be very sexist, which is why I mostly game solo, but said that calling it the most sexist culture ever is to be either naive or sheltered and cited several instances where women are legally disenfranchised or targets for revenge killings and outright murder.
"Stop using your racism to defend your sexism!"
They trivialize the very real plight of women around the world, yet I'm the sexist for pointing it out. After that, I called them out for what they said, offered a few observations about their general intelligence, and left the thread. Perhaps I should have taken them to task for their own racism. Guaranteed they wouldn't have said that if the women in question where white.
