[Still Growing]

I think the major issue is that its encoded in humans DNA to herd. This creates the scenario whereby people judge the minority by instinct.

By minority I mean any group which is not in the majority at any given time.

So if a white person goes into an area whereby they are the minority it is often they they will be judged more critically. Or if an atheist happens to be around a group of religious people.

I have lived in other countries and I can tell you that racism exists every where! After some time of observing this I realized that its not actually racism but other groups herding and being critical of my being the minority in that arena.
