Do you think in 100-200 years people are all going to mixed with different race?
Look at all those white women with their black Kings :) talk about black man victory.
No, a lot of white people will still only be with white people. A lot of asians will only be with asians. Blacks with Blacks, Natives with Natives. Brown with Brown. I don't think that will entirely change.
Most people still prefer to date, marry and have children with people in their own race.
By the way that's not racism just preference.
