What Jews in power in Germany?

I'm not the expert on those specifics but as I understand it he made regular claims about jewish banks and influence in commerce being used to destroy germany. He blamed them for the hyperinflation and many other things. Interestingly there was the same kind of social degeneracy happening there with regards to transexuals and homosexuality as we see today in the US, except it was 100 years ago when the world was far more conservative and Germany was leading the "revolution". A lot of the book burnings were LGBT propaganda written by jewish authors.

While it is important to understand that these reasons existed, it is not important for the topic of holocaust denial whether or not they were valid. It is only important to understand that hitler, and many of his followers, believed they were valid and wanted to save germany from that evil.
