Alright, now at what point after the revolution has been won is that achieved? The day after? If not, might there be a transitionary period?

Point being that socialism is the word used by MLs to describe the transitionary period, and communism to describe the post-class society where workers own the means of production. So "this is/that isn't socialism" is deemed useless moralistic leftwing anticommunist rhetoric, and really just not productive. You're more than welcome to critique this transitionary period (I mean by god there is a lot to critique about China and please do), but you should view it within the context of this period. Socialism isn't a static checklist of policies.
