telling racial jokes, stereotyping, and laughing or making fun of people's differences may not be the same as forcing blacks to the back of the bus or refusing to serve them in your restaurant, but it's not a healthy thing by any stretch of the imagination. with kids, it fosters an attitude of "you're not as good as me because you're different" or "i'm better than you because xxxxxxx." none of it is good, whether it's actions, words, or a secret prejudice no one knows about.
