Socialist democracies are cool. Think Denmark, Finland, Iceland, Norway, etc
Socialist authoritarian states like China, the USSR, etc. those are not cool.
The problem isn’t having social safety nets and collective control of shared critical resources like transit and healthcare. The problem is when you don’t let people vote for their own best interests.
They are not socialist. They are "Social Democratic", capitalism, but the workers get a bigger share. The parasites known as Capitalists, or Burg... fucking french... Bourgeoisie, are still a thing. The workers do not own the tools.
I can see that you are somebody who takes the subject of fascism seriously. Have you considered subscribing to or lurking !capitalismindecay@lemmygrad.ml? Although it currently only has one regular contributor, I update it frequently and I am willing to answer whatever questions that you may have on the subject.
Did you ever heard the term Anarchism. Or Anarchist/ libertarian socialist like Kropotkin, Bookchin etc. Or things like Rojava. Or any socialist projects which really gave what they promised, since there means marked their end?
All socialist and not slavery like most of the things you counted
Also the parts I know about Marx is actually not to bad.
