Black women have told me it's because I'm a sellout.
The white men who can get past the mental anguish of my black penis tarnishing "their" women think I'm making some latent admission that their race has the most attractive women.
The concept of a black man in a relationship with a white woman is a "thing" that people have an opinion on, and that opinion comes with an entire set of stereotypes, fueled by racist ideology, a complicated past, and sometimes even pop culture.
Kanye West once rapped about how successful black men will "leave your ass for a white girl," and then put himself into that box by marrying a white woman, furthering the pervasiveness of flawed, generic ideas about interracial relationships.
A racist jury acquitted his murderers, Roy Bryant and J. Milam, despite overwhelming evidence, and, to rub salt in the wound, both admitted to killing Till in magazine the next year. The shoe was on the other foot for once and so be it if two white people wound up dead. That's harsh, but that's the historical context of black men dating white women that I unfortunately have to consider when doing the same. Even then, I understood that it was racial, but there was a disconnection from my personal reality. Whatever I learned from the trial was tucked away as something that I should know as a black man, but it didn't have a life-altering impact on my own development. For whatever implications the trial had, that shit also had nothing to do with me. My attraction to them was likely a natural response to my environment. Nobody was trying to assimilate with white people, but sometimes that's just the way things go when you want a better home and better schools for your family.
