Look it up. It's in the history books.
Mein Kampf is not a history book son.
Nope. And the slaughter Hitler admired, and was inspired by, was that of the Native Americans.
"Thus suitably motivated, they proceeded to massacre the Jews in German cities like Mainz and Worms. Thousands of defenseless men, women and children were chopped, burned or otherwise slaughtered.
This sort of action was not an isolated event — indeed, it was repeated throughout Europe by all sorts of crusading hordes. Lucky Jews were given a last-minute chance to convert to Christianity in accord with Augustine's doctrines.
Even other Christians were not safe from the Christian crusaders. As they roamed the countryside, they spared no effort in pillaging towns and farms for food. When Peter the Hermit's army entered Yugoslavia, 4,000 Christian residents of the city of Zemun were massacred before they moved on to burn Belgrade."
What Were the Crusades?
