Communism will always be violent, page-211

Hitler's first task was to round up and kill all of the socialists. That's why capitalists loved him. Hitler smashed the unions and killed or imprisoned all of the leaders. Workers had to be made to know that they belong to capital, not allowed to argue. Look at Hitler's luxury stay in the prison hotel after the Beer Hall Putsch. Real socialists like Rosa Luxemburg were among the hard rights' first victims even before the establishment propelled the Nazis into power.
