Parents and schools should place great emphasis on the idea that it is all right to be different. Racism and all the other 'isms' grow from primitive tribalism, the instinctive hostility against those of another tribe, race, religion, nationality, class or whatever. You are a lucky child if your parents taught you to accept diversity.

You have to look at the history of the Middle East in particular. It has been one of failure and frustration of feudalism and tribalism.
