I was also shaken to the core by Dachau. However, I looked not at Germans but at people all over the world and wondered how can I love you knowing that you are capable of such as this. I looked into my own soul, and there was the answer.
But "all" people are not capable of doing this. We in the US, as a people, would never do this. Nor could most individuals in a "civilized" society be swept up into this. At that time, I was looking at people who may or may not have been directly or indirectly involved in the systematic elimination of a people because of their religious belief. It wasn't an esoteric question of all humanity, it was a question of personal responsibility.
One of the strange tragedies is that the Germans wiped out some of the death camps before the Allies got to them. They were razed to the ground and the inmates transferred to other camps. The only thing left was the roads, concrete foundations and unmarked graves.
