To be fair, I see plenty of white chicks falling for dudebro types who treat them like shit. It's not a black thing, I just "know know" more black people than white people, grew up around them etc.
Lots of guys run into the same problems. Personally I've seen many black friends chase after the sorriest black guys, get burned, then want to go to Starbucks with me. Next month whoops, dating another dumbass.
