What am I prejudiced about?

I think I am most prejudiced about people being racist and mean to other people. I can't stand hearing kids in the hall constantly making fun of other kids they don't even know. Sure, I do mess around with my friends, but we all do. We all know each other well and know that we are just kidding. But, when people make fun of, or are racist, to someone they don't know it is so wrong. They are probably very nice people. Also you don't know what they are up against at home. They could be going through a very difficult time. I hear the saying all the time, "treat others the way you want to be treated." So very true, but how many of us actually do it? Not too many. If we just followed this simple guide line the world would be a much better place.
