Red fascism
Red fascism is a concept equating Stalinism and other variants of Marxism–Leninism or communism in general with fascism. As a term, it dates back to the 1920s and was originally used by left-wing individuals who were critics of Bolshevism; by the 1940s and the Cold War era, particularly in the United States, it was adapted as an anti-communist slogan within the framework of totalitarianism.
