Yeah, but that’s the problem. Communism sort of relies on that communist state transition period. Or at least, that’s where every single communist state has turned into a dictatorship. The party-in-the-meantime never gives up their power “after a communist utopia sprouts.” That’s really the main leftist communism critique.
Socialists, communists, anarchists all have very similar ideas of a socialist utopia. But it’s how we get there where we all differ. Anarchism is communism minus the ruling party while relying on people to be good, self sustain, and fight back together when under attack. It would be great if we could have some left unity, but….well, ask the FAI how that went.
