What was the chief reason for adolf hitlers anti-semitism?

Answer 1

His group fought pitched street battles with the Bolsheviks (90% J e w s) who wanted to make Berlin into the spearpoint of Communism for all of Europe. That was one thing. There were many more, one being the tides of pornography, produced by J E W opportunists that were being pushed into Germany after it's loss in WW1. The chief reason though was the fact that in 1933 world J e w r y declared a financial war on Germany and this is documented in a New York newspaper.
