He had anti Jewish stances but there were far worse people than him. It is unfair to mention him without mentioning others. For example Muhammed was far worse and very anti Jewish, too, the guy that founded Islam. His racism even lead to mass murder or genocide on Jews and racist laws against Jews in the Quran (also against Christian and Atheists). Xenophobia is not that seldom with religious leaders because they are sometimes influenced to some degree by the negative principle. You have to distance yourself from the bad parts in the religions, anyway. There are a lot of religious people that were pretty xenophobic. And Martin Luther was not the worst.
Who cares about others? I don't..I could give a shit less about Muhammed..Did he hate Jews as well?
Yes. He even made racist laws in the Quran. He is always defended by the world despite his racism (because the media representatives themselves are racists) but Martin Luther is critiziced and that is hypocrisy (not of you of them. I just wanted to add that) He was one of the smaller racists. Antisemitism was pretty widespread and not only in Germany, that was spread around the world.
Yes the theories are similar to the theories about the Illuminati (that is what I would say). Hitler hated capitalism and Communism because he thought it was controled by Jews and Jews=Illuminati in other theories.
