I read something interesting, what do you think? (a little long)?

A while back I read an interesting article. It said that we inherited a tribalism trait from our ancestors (don't quote me on the terminology). It said that our ancestors were part of tribes our groups and their survival meant the destruction of an opposing tribe, or that the survival of the opposing tribe meant the destruction of your own. So because of this our ancestors had to be able to spot those which were different and kill them.



This trait today, forces us to point out those that are different and view them as enemies. Which explains things like racism, nationalism, etc.



A study was done on delinquent youths and they were asked if it was ok to steal from an elderly lady. They said it was not ok, and then they were asked who it would be ok to steal from. And they responded "maybe the Chinese delivery guy." They came to the conclusion that because the delivery man was different, it was ok to rob him. I was wondering what everyone else thinks on it.I read something interesting, what do you think? (a little long)?

There was a British school teacher in the 1960's who divided her class into the blues and the reds. Blues were taught that reds were inferior. At the end of the game the belief persisted. Some "reds" were still having trouble with the "issue" 20 years later. The sides were chosen randomly.

In a general sense, there is no question that our primate past explains much of our violence
