Consider that as a class, black women are placed lowest on the pole of attractiveness and bi racial "black" women often have trouble fitting in with the black community on top of that. I would probably be bitter too - especially if, as is commonly the case, you're the product of a white mother (generally considered the most attractive) and a black father, the type of man who rejects women that look like you to chase white skinned women. Your largest pool of potential mates are black men who statistically have sky high STD rates, domestic abuse rates, child abandonment rates, marriage and divorce rates, awful income potential etc and most of them will drop you in a heartbeat if a white woman gives them a chance.

More and more of these bitter women are going to be produced as more white women pair up with black men (and to a much lesser extent white men with black women). And society and media will work to convince them all that this is the fault and plot of white people (especially white men) rather than the absolutely terrible state of black men and their treatment of their own women or the white women who enable this grotesque situation.

Somewhat the same could be said about hapa males, except of course without all the awful statistics mentioned attached to the men.
