I agree that I disagree with the song "You have to be carefully taught." While there are some obvious cases of carefully taught hatred. I believe a lot of predjucices are learned from a snide comment here and a misunderstanding there. I also believe some hurtful things said are not meant, simply because what was said and what was understood aren't always the same thing. I'm sure a chat group about words knows the power of words. Sometimes the delievery is imperfect. We don't realize how ugly it sounds on the other end. Perhaps it's hard to understand how ignorant "Black people eat fried chicken" or "Chinese people own laundries" sounds until it's happened to us. And Maybe? when we talk about a good word gone bad, we're not saying something nasty but commenting on how the definition has gone from meaning happy to homosexual to uncool.
