The problem is that white people see racism as conscious hate, when racism is bigger than that. Racism is a complex system of social and political levers and pulleys set up generations ago to continue working on the behalf of whites at other people's expense, whether whites know/like it or not. Racism is an insidious cultural disease. It is so insidious that it doesn't care if you are a white person who likes Black people; it's still going to find a way to infect how you deal with people who don't look like you.
