Thank goodness this was done one time, recorded, and shared over the years. It's borderline child abuse and I'd hate to see another child go through this experiment. That said, it illustrates how easy it is to create a real problem. So sad. Why are we wired this way? Is is primal? Module one says race defined different families. As the world got smaller, race got redefined into types of whites, to all whites, etc. That means we were always in a nature of conflict. "Us" and "them" is woven in the fabric of who we are. We are virtually re-wiring our natural instincts. That's higher level stuff.
