Not every book from a Jewish author was communist propaganda and subversion. But a high % probably were. It was easier to ban every Jewish author, than to sort out Zionists. Zionist propaganda makes it seem as though the NSDAP disliked Jews, for no reason. Zionists never talk about the Balfour declaration that caused Germany to lose WW1. They never mention the oppressive treaty of Versailles and the Weimar "government". And they never talk about Jewish Bolsheviks that committed the red terror, holomodor, and other atrocities. Jewish Bolsheviks threatened to do the same thing to Germany / western Europe. And that's 1 of the many reasons why Jewish people were considered enemies of Germany. After the bombing of pearl harbor, Japanese americans were considered enemies of the USA.
