In thousands of years, humans will integrate to the point that race is no longer an attribute to get worked up over. I predict race will still contain historical importance, but will be mostly referred to in an aesthetic manner. Our human genetics would still create a general fear of the unknown, but only ignorance creates hatred between races, and instincts will prevail! Put a neo-nazi woman in an abandoned town with a hesidic jewish man, and they will probably procreate anyway. That approach makes a lot of hate-fueled acts futile, and makes racism pointless.
