That is a very good question Zilla.
You would hope that we as a society are trying to get to a post-racial era, where race is not a factor in anything that we do.
So its a bit troublesome, when black women seem to deliberately seek "good black men" instead of just "good men".
However, the fact of the matter is this (imo anyways), given the history of race relations in the U.S., and its lasting effects, the "black experience" in this country for the most part is still very different from the "white experience". Even black kids raised in the suburbs (such as myself) tend to have distinctly black cultural ties and life experiences. They are simply a lot of cultural elements and life experiences that black people share because American society has pigeonholed them together, that they do not share with white people. Its not that black women do not ever find white men attractive, but that they think by dating a "brother" they will be dating a person who can relate to them on the issues that are overwhelmingly specific to black people, and one that can identify with their "blackness", which is a still a major source of identity for a lot of black women, and black people in general. It should be stated that the fact that many black people embrace a black identity separate from mainstream America does not result from black peoples desire to be different, but is a reaction to the fact that they were TOLD they were different and were TREATED differently for centuries in this country for the SOLE reason that they were black.
This is nuts. I mean, it sounds true enough, but still, I can't fathom how big the states are that there's such diversity from one area to the next. There are parts of London I don't know about, so, wow.
You would think though, that the opposites attract rule would work here. I know that, personally, it's kinda jarring meeting someone similar to myself. So this apparent black woman's search for a black man -- or at least someone with the same reference points -- must be kinda hindered when someone comes along and it's purely physical. So maybe it's just for long-term relationships that this is an issue, if you can call it an issue.
