re: Nazis and Communists

You did say I was confused, as though I didn't know the difference between the socialist and communist phases. In the common parlance, Marxism generally refers to the socialist phase, and not the communist one. I could have been specific and made distinctions between Marxist-Leninists, Left Communists or any of the other varieties, but Marxist-Socialism describes all of them. The only distinction that should be made, in my view, is the one between the anarchist and Marxist factions, as the former was explicitly anti-authoritarian.
