I'm sorry, it doesn't work like that, while there might have been some Black men (and women) upset by her role in that movie and the fact she won an oscar for it (to put it better, that the AA''s would give her and Denzel awards for "negative" roles), if Halle were to dump her model baby daddy, do you honestly think Black men would stay away?
If she were put on a Black mens magazine, we would be to busy looking at the pictures to even bother to get upset like the essence readers did over Reggie. Fine is fine, and going with a White man doesn't make an attractive Black woman any less so, and I say this for the Black men who only/mostly go with with Black women. Plus, they know Halle was with Black men for years, I doubt Essence readers care about the prior relationships of the Black men who are now with White Women. No BM here should be crazy enough to care and they realize she is half White anyway.
