Well again, how are we defining Nazi ideology? What Hitler thought? Not sure I know what he believed in, after all he would be pretty pally with the church one moment and then equally close with the Thule mob the next. On the other side, the occultists were a total mess, little continuity and all kinds of mumbo-jumbo cherrypicked from (often badly researched) pagan beliefs. I'm really not sure that Nazism had any specific religion though I agree with Kai that (much like communism) the idea was that eventually Nazism would take the place of religion.
