I write the following from what I have personally experienced/witnessed so I realize it does not apply to everyone, but it's another perspective to consider.
I know a lot of women and none have ever been interested in thugs. We came of age before the era of the glorified thug. It may explain problems in the 20 - 30 age range, though.
What I have encountered with men my age (40s - 50s) is that while in their 20s - 30s, they choose to remain single while replaying their adolescence. Having earned college and professional degrees, they were making good money, had their own place and a nice car. As the "cream of the crop" the pool of available women grew, and they could pick and choose. On the other hand, their female counterparts, with whom they'd shared high school and college, and with whom they had socialized for years, were forgotten. Add to that the onset of the thuggish male generation, and the pool of "good men" for these women shrank. So, a generation of eligible women was alone for the better part of their prime marriage/childbearing years. The good thing is that many of these women use the time wisely to build their education and careers. I even know a few that have adopted children.
Quick story: A man of 35 who was interested in me called me "an old B" (literally) when he found out I was 39. Eight years later, this man is still single at 43 and still very much the adolescent despite his other life accomplishments.
As for dating/marrying outside the race, I only know a few black man who are married to white women. A lot of black men date/marry Latinas, because (I am told) when seeking a woman who is "traditional" and beautiful, they have the complete package. However, I have started to notice an increase in the number of black woman/white man relationships/marriages -- especially black women dating/marrying European men -- who don't have the same racial hangups that Americans have.
