On the one hand, I'm not in a place where I can question the lived experience of your roommate. On the other hand, a sexist-racist heuristic is still sexist and/or racist.

If I, as a Chinese dude, stated publicly that I don't want to date Chinese women because they're hyper materialistic and status seeking (not a belief I hold irl), I would hope that people would speak up and tell me that that's a fucked up thing to say.

Or, to remove the gender and patriarchy angle from it, if I got mugged a few times by people of a certain racial group, it would still be really fucked up of me to claim that I have a heuristic where I avoid people of that race.

That's why she dates men from the culture that invented lobotomies specifically for their wives ofc.

Sounds like the straight equivalent of "no blacks, no fats, no fems". Came to call those 'three no's queers'; I threw out dating apps after more than half my locality where I used to live had that at the TOP of their profiles.
