Why are people racist?

People are racist because they're afraid of thinigs they don't understand, and are afraid to confront the way they feel. Subconciously, they know they're wrong but they simply can't face that. So it makes them angry. And since they'll never take that anger out on the real problem their ignorance, will take it out on what they perceive is the problem with other races. I think we all need time to get used to change and things we are not familiar with. There are wonderful people in all races. We can learn a lot from each other. Racism is a learned trait. Humans are very competitive and if we can find fault with someone else then we make that a gain for why we are better. This does not stop with race, it could be religion, sex, height, weight, eye or hair color.
