Not OP, but the processing of learning that being X isn't a joke in and of itself taught me respect for other groups. You compare the joke about being gay vs a joke that someone is gay. One is a funny commentary on the gay experience, and the other is homophobic. Learning that difference, through experience help teach me where to draw the line between appreciating other cultures and cultural appropriation. And yeah a lot of these lessons can be taught other ways, but I have often found experience to be the best teacher. We should encourage kids to discover better morals and not just follow the morals they are taught. We learned a lot over the past century letting kids do that, we shouldn't stop now. The youngest generation has constantly shown the older how to be more accepting of neighbors, and kinder to our friends.
