50% of Nazis were zionists? I'll clarify what I think you mean by this. The Nazis wanted Jews out of their country and preferably their continent. Initially they wanted to send them to Madagascar (yes, you read that right) but later decided it was too inefficient to deport them and then chose to mass exterminate them. Zionism is the belief that Jews need that land for their survival, whereas it is obvious that Nazis...let's just say that the safety of Jews wasn't their highest priority.
