Why does this come as a surprise to anyone? It's not like racist people live in trailers deep in the South, all together on one big plot of land, possibly missing front teeth so it makes it easy to spot them. Racists are all around us in all spheres of society.
The only way to win, is not to play, and refuse to prticipate when you see it played by others. Remember, those with bias feel that it helps their life somehow. Few are trying to promote strife for its own sake. There is no 'other side', we are all on the same team. We win with love. Meet people where they are at, and guide them to wisdom. Yelling from the other side of the divide that they are bad and wrong will never win a heart. Misunderstandings are all around us, in all spheres of society.
