When I was a kid, we often played cowboys and Indians or sometimes we played soldiers. Always divided into good guys and bad guys. Some of us were very good at being shot and tumbling in magnificent form as we fell dead on the ground. Sometimes even praised by our fellow combatants at how expertly we died. I never wondered then, as I do now, why little boys and men are so possessed by killing each other and why they enjoy it so much. This is not new; it has been the case since we climbed down from the trees. Will we ever change? Probably not.

The only way humanity can survive is if we truly and honestly learn to embrace our differences
