They often have socialism in their name, but I don't really consider them socialist, as you said - they're welfare state supporters, which is really, really far away from socialism in soviet controlled eastern europe
plenty of democratic socialist parties that never devolved into rampant totalitarianism like the leninist parties did
I guess you're right there, still, they tend to be authoritarian - socialism in the soviet controlled republics was rather ugly - centrally planned economy, rationing of everything from meat and sugar to cars and housing, censorship of any political subject in media, ever present corruption, berlin wall to keep people from escaping...
As far as I know, no, there aren't any - every single example of "working socialism" they give you, are basically welfare states - capitalist countries with high taxation going towards social benefits - like free health care, free education, social security and so on.
They're cultists. If you talk to them in neutral sub, You'll find horribly defective logic and broken definitions ("Your definition of Anarchy is wRoNg, anarchy is an organised system!!!").
If you try talking to them in one of their sub, you'll get banned instantly. Socialists/communists are pro censorship and therefore pro coercion. No wonder, every communist state turned into dictatorship.
Well Socialists/communists from lemmy.ml will tell you that you're wrong - you escaped from heaven on earth into capitalist exploitation grinder, and actually Cuba is perfect equal economy, destroyed by evil western sanctions.
