This is a topic that's been tossed around quite a bit in the past (and I wanted to get a current sentiment), but this is for non-black guys, or non-black girls.
As a non-black guy, would you date a girl who has dated or messed around with a black guy. In several circles I've lived in, among white guys, the answer is typically no.
For non-black girls, if you have dated a black guy, has this become an issue for a non-black boyfriend (or dating prospect) in the future.
