Nazi antisemitism had nothing to do with Christianity which Hitler rejected as a weak Jewish slave religion. Hitler's antisemitism was based on the theory that a Jewish-Masonic conspiracy was out to get Germany. He got that straight out of the Protocols. Nothing to do with the crucifixion of Jesus at all. Christianity was believed to be part of the conspiracy to make Germans weak and make them worship a Jewish God.
It wasn’t about where got Hitler his stuff. The hatred of Jews already existed.
No single figure in history contributed more to this than Martin Luther.
The notion that Hitler promoted a new idea that a blank slate of Germans is ludicrous.
