Red Fascism
Red Fascism is an authoritarian form of communism (similar to National Bolshevism) that are used to establish a dictatorship. Despite being called socialists, the Nazis were not Red Fascists, and were simply a separate branch of Fascism.
Some groups of red fascists, referred to as tankies, support dictators such as Stalin, Mao, and other communist dictators as well as their ideologies.
