I wish I could explain that one
HOW the people allowed such a situation
. But explaining and analyzing the mechanisms of propaganda and steady radicalization of the Nazis is one thing, understanding how regular, normal people were able to lose so much of their humanity and commit crimes on such a scale that it lacks adequate words to describe it or how they were able to plan exactly how much a KZ prisoner had to able to work to make the max profit as they worked them to death in the german industry is another.That is the worst thing, Silver, the ingenuity and perfection of the whole process.. the Nazis took stereotypical german qualities that used to be held in positive regard like punctuality, hard working people, precision, perfectionism, authority etc and made the worst mockery out of them that is possible.
Sigh, a truly german issue is on how to come to terms with that.
Auschwitz looks nice if you go there, neat red brick barracks, flowerbeds.. it doesn't look like a place where so much suffering took place at all, it is not horrific. Even if you are right there it is impossible to comprehend and grasp what took place - you can't and everybody fails who tries it.
