The need to identify with a social/tribal group is not inborn, it is forced onto children at school. If it was inborn then everyone would display this need to identify and empirical evidence tells us that this is not the case. Those of us who understand this need is both illogical and harmful fall into two categories, those who were not convinced by the propaganda from the start and those who've overcome the propaganda through education. As I changed schools 19 times I'm fortunate that I mostly fall into the former category although there may be some shades of grey in the middle.
