By your logic USSR was far right.
I also highly doubt USSR would accommodate people who move in and don't bother to integrate into the culture and speak Russian. Ask people from entire countries where Moscow did Russification, and those people didn't even move in from outside they already lived there.
USSR was schizophrenic in that regard. Early on, it had https://en.wikipedia.org/wiki/Korenizatsiia, which was quite literally about de-russifying the local elites and promoting local languages. Then Stalin did a hard 180 on that, like he did on so many other things (e.g. re-criminalizing abortion and homosexuality, or reintroducing paid high school). I don't think it's unreasonable to argue that under Stalin, the USSR truly switched from being a left totalitarian dictatorship to right totalitarian.
They had strong opinions of what was deemed "socially useful" work and were not above abolishing those pursuits they deemed to be useless.
All able-bodied people were expected to work (in approved roles) and you would be provided a job if you couldn't find one but if you refused to work they would deem you a "social parasite" and prosecute you if you didn't reform your behavior.
Somehow, people seem to forget that Marxism is an ideology of workers.
Not really, Marx and company were nobles, lawyers, etc. The ideology concerns provoking a civil war and taking over, workers rights is just the rhetoric to cause the revolution. The worker’s paradise never materializes because it’s not actually about that.
Not all of the component parts of the ideology are necessarily false due to their introduction and popularization by Marx. Personally, I find his writings obtuse and his beliefs abhorrent. There is, however, merit in the idea that the state should benefit its people, a large percentage of which are the productive working class, but it shouldn't be ruled by the working class. The state is its people and their culture, it shouldn't oppose their interests or subjugate and exploit them for the advancement of ideals alien to them.
Why not, though?
I mean, if you subscribe to democracy, the only way this would not be true is if said democracy was somehow subverted into a caste system where only some people are de facto eligible to be elected.
