I’ve gotten the impression that a lot of people think that they’re not racist just because they don’t use the N-word, or they have some black friends. But there’s really no way to not develop some ingrained racist beliefs just growing up and living in this society (unless you are someone who is just incapable of learning). I think that most people of my generation have heard their parents say some pretty damn racist things too. So, I would say to these people: first acknowledge that you almost certainly hold some racist beliefs. (I think that people are more likely to accept that than to accept that they are a racist, which is something that most people think of as innate and unchangeable). Then you have to actively challenge those racist beliefs. That takes effort and action. But in the end, I think most people who do this will become happier people with fuller lives, since racism causes fear and wall building.
