Of course white supremacy exists and white women are the standard of the ideal woman in the US. I'm sure they affect black men's choices.
I'm sorry, but I disagree; Don't you think it's a little bit over the top?
Don't speak on behalf of others, saying what anyone else thinks.
People who claim that a white person is the ideal person in any scenario tend to have very racist tendencies and I sure do not hope that you're like that. Instead of you claiming that black men prefer white women and somehow clouds their judgement, why not try to focus on black women's qualities and how they are also a unique group of individuals with different strength and weaknesses from white women?
