Yes, they, as a people, are going to have to get over it, and move on with their lives, but that is a lot easier to say from where we are sitting.
I have no fear of the future however. In 20 years, I believe that they will be melted. Starting with my generation and now with the current generation of kids, we all grew up with the black culture all around us, and we embraced it. So it won't be so much the black culture melting into the "white" culture, but more of a meeting in the middle. I believe more and more of our kids are growing up colorblind and I believe it will reap great benefits in the future.
A white kid has no shame when he wears his hat backwards and listens to "black music". A black kid has no shame when he wears polo shirts and golfs at a country club. We are making progress.
