I think @Cowbee@lemmy.ml already covered these, or at least some.

1. By state, communists mean a system that enforces the will of one class over the others. A stateless society is a synonym for a classless society. It doesn’t mean there’s no government.
2. No socialist state has achieved communism in the past because it is necessarily a long-term project. You can’t simply go to bed one night in a capitalist state and wake up the next in a classless society. Certainly none will achieve it while imperialist states are still working to deny it. They are in a stage of siege socialism.
3. “Autocrats.” That’s not how democratic centralism works; that’s how Western capitalist propaganda tells us it works. From a declassified 1955 CIA report:

   Even in Stalin’s time there was collective leadership. The Western idea of a dictator within the Communist setup is exaggerated. Misunderstandings on that subject are caused by lack of comprehension of the real nature and organization of the Communist power structure. Stalin, although holding wide powers, was merely the captain of a team and it seems obvious that Khrushchev will be the new captain.

4. No communist worth their salt ever talks about any sort of utopia. Marxists are materialists, not idealists. This is basic stuff.
