One thing: Hitler waged his war on the stance of racism. It was all the craze to blame Jews for everything at the time. Hitler got most of his ideas on how to persecute the Jews from the Catholic Church. Even the famed "Protestant Reformation" leader Martin Luther was EXTREMELY against Jews. He condoned hate crimes and even murdering of them.

Look at what the father of the Protestant faith has to say about Jews.

Germany needed someone to blame for their failure to win World War 1. They were content to believe that Jews who had infiltrated the highest levels of the Germany government surrendered to the Allies when they could still win the war.
