What is Marxism?
Marxism is a theory that communism can be achieved by using an authoritarian socialist intermediate stage, known as the dictatorship of the proletariat. It has consistantly failed to reach communism, though, as you should know. Totalitarian socialist intermediate stage, you mean. And the fact that anybody would start a thread in defense of such an odious man and an abominable system as communism is abhorrent.
