We evolved a lot regarding racism, backward and forward, is certain. If you look back in history, over the last thousands of years, you will find that racism existed among groups, back and forth throughout all those years. Racism and the lack of it are nothing new. Rather, it is kinda natural that it happens both ways at different times.
