Saying that communism leads to fascism is a silly concept that I don’t feel the need to expand on. All states are authoritarian so I’ll give you that one atleast but I don’t think we can get to a stateless society without a proletarian state in transition. We are never truly free under any state society so yes personal freedoms are restricted but this isn’t unique to socialist societies. The question should be what freedoms are restricted, how are they restricted, and why are they restricted. Personally I believe the freedoms restricted under a socialist state are preferable to the freedoms restricted under a capitalist state. I don’t think people should be free to own private property (property that exist to produce private capital) for instance. I do think everyone should have the freedoms that proper medical care, education, and employment; freedoms which are up for debate under a capitalist state.
