Impossible. We already have millions of interracial people and will have millions more in the future. For example, one of my friends is half black/half Korean. Another is a fair skinned, green eyed Jamaican. My secretary is half white/half Filipina. I have good friend who is half German/half Palestinian who is married to a guy who is half black/half Palauan (and they have two kids). I have another good friend who is Chinese. She married a guy who is Hawaiian/Chinese/white. They just had a baby. This is the future of America IMO.
You also have to take into context, of how one views another or themselves. For instance, several Hip-hop video vixens are half Korean/ half black, both of their fathers were in the military. Now if your culture, (African Am) has more "strong-headed" women in it, and in Korean culture (especailly old skool Korean) the women are taugh to be demure, and submissive. If your in the military, would you want to hear mouth, or get a good meal.? You pick.
You saee many African Am. have such low self esteem ,it is unreal. I know of three women who want to have light skin babies, because they view their dark skin and ahir texture as inferior. One is dating a white dude, another a light Hispanic, and the other likes me. I cannot get with their mentality, nor do I want some child that thinks they are more supeior to other black childen because he or she is lighter than them.
Have you ever talk to a black person, who everything other than black? For instance, they are quick to say: "I have Cherokee and Italian in me, that why my hair is so 'good'. Girl, you know I got that good 'baby hair' rockin'.
With instances like this, Racism will always exist, only until one over-comes their own biases and prejudices of themselves, will racism soon start to erode.
