German Nazis and German Communists (who were very much not the fluffy Euro-Communists of the Cold War) made up a majority of the German population. The ends to which people were forming active, violent militias were different, but when massive groups of people are taking up arms, a society has chosen the path of violence. German elites, conservatives, and moderates actively chose to let the Nazis take power, because it seemed superior to the alternative at the time.

The Jews etc. were the scapegoats of Germany, and the party and their leader rose to power because Germany was the scapegoat of WW1 (justly or not). I don't imagine that Hitler and his party would actually have gotten such a foothold if it wasn't for the fact that the German people were resentful for being under everyone's heel, and that Hitler's leadership brought Germany out of a slump in the 30's.

No? My knowledge of history is rusty.
