hmm if you are condemning these acts from comrade Stalin, I think Marx encouraged dictatorship of proletariat, Karl Marx believed in a transitional period in the road to total communism this being a socialist state under a dictatorship authority of “the people’s party”, even the acts of purge that Stalin carried I think were mentioned by Marx, I personally don’t think that Stalin betrayed Marxism, but if Marxism is a totalitarian system, and we’re here calling totalitarians “fascists” then Marxism is a form of fascism
