These people believe in the myth of "Western Civilization" that is taught in virtually every college and university in the USA. They don't consider Mao, Stalin, and even Lenin, to be a part of "Western Civilization". From there, it isn't much of a step to go fash and say that Marxism is an "Asiatic ideology" that feminizes men and "masculinizes" women. Socialism is Asiatic, other, and feminine. Lenin was depicted as a scheming Jew in fascist propaganda. Stalin was always portrayed as Georgian and Asian.
Orientalism plays a large role in why people over estimate the "death toll of communism". The Holocaust that the Nazis carried out was particularly horrifying to Europeans. European Empires such as the British East India Company had committed mass atrocities and genocides for hundreds of years in places like India, China, Africa, and the Americas. This was the birth of capitalism, in blood. The idea of Europe having this level of genocide horrifies the Reactionary Mind.
Edward Said's book on Orientalism explores the subject further.
Dude, your whole argument comes from this documentary that was on Fox News.
Dinesh D'Souza is the one who started all these bullshit lies about the Nazis being left wing.
Seriously. The article is jaw droppingly dumb, I can't imagine what reading the whole book must be like. I have to say though, reading the Amazon reviews is pretty good if you've got a stiff drink.
