Hitler describes the “chill down his spine” when he discovered the rampant sex slave trade was almost exclusively run by Jews. (excerpt from Mein Kampf)
You should read "WITH NAPOLEON IN RUSSIA ARMAND DE CAULAINCOURT, DUKE OF VICENZA 1773-1827" FROM THE ORIGINAL MEMOIRS AS EDITED BY JEAN HANOTEAU.
Jean was a member of Napoleons Imperial Guard and described how the jews tried to rob and murder French soldiers during the retreat.
Hitler didn’t “discover” a fact, he repeated long-standing antisemitic propaganda myths that were later formalized by Nazism. There was no “almost exclusively Jewish” sex-slave trade in Vienna or anywhere else.
This passage from Mein Kampf is a textbook example of scapegoating: take a real social problem (prostitution existed across all European cities), falsely assign it to an entire ethnic group, then use that lie to justify hatred and political violence.
Historians are clear on this: Nazi claims about Jews controlling prostitution were fabrications, not findings. The text is studied today to understand how propaganda radicalizes, not because it contains truth.
