If you don't believe me, sit and take account of black male celebrities (including athletes) who have non-black girlfriends or wives and ones who actually have a black woman.
You say the most "notorious" guy usually has a white girlfriend.
My observation has actually been that the more money a black guy has or obviously will have some day, the more you can just about bank on his having a white, Asian or Latina female on his arm.
With other black guys, you might see them in interracial relationships, but it seems less likely just because--and this might seem offensive, but--the average white woman cares about money in a man a little too much to be dating guys, especially a black one, who doesn't have much and because black guys with less money tend to be in predominantly black environments (making it more likely he'll get with a black female) more than black guys with money.
Black women are among the least aggressive, and part of that is just being socialized as women that men should approach women.
I see a lot of black women interested in men, including white guys, but they insist the guy has to come to them.
Less white women do this, and this has largely become more of a cultural difference than a gender difference.
With white men not being as aggressive as black men or white women, combined with the extra racial issues when a white guy is interested in a black woman (not even just racism, but more like "whoa, how do I approach a black woman?? I'll probably get rejected"), that leaves a lot of black women waiting forever and ever for an approach that is not forthcoming -Like some others have suggested, black men view white women as a prize and a step up in society.
How did this white woman + black man relations trend start ? It would be easy to say this is just breaking barriers. In my community i don't notice many black women and white men dating.
However every so often I come accross a couple of a white woman and a black man.
In fact, very often, its the most notorious guy in the neighbourhood that has a white girlfriend. Why is a relation of a white woman and a black man, more common than vice versa ?
Black man/white woman is more common for a lot of reasons: -Black men are probably the most aggressive I've seen as far as pursuing who they are interested in, white women probably second.
