Every year on the 4th of May, the Netherlands memorizes their deaths of world war II When I was a toddler to teenager, every adult had memories of The War. Yes I am that old. Everybody knew plenty of people who died due to the hostilities or due to the holocaust. And every conversation in those times turned to that subject, invariably, ending to the question, how was it possible? How could a complete population, our neighbors, normally nice and kind people, have turned into such monsters? What could possibly be the force behind that, to drive normal people to such a madness? And then silence. Of course nobody had any sensible answer to that. But we all vowed that it would never ever happen again. Nowadays after decades of good progress in sociology studies, things slowly start to get clear. It seems that everybody needs an enemy. Does that make sense?
