I’d argue that for several of the “experiences” on this list that success really depends on who you are and they aren’t or weren’t so great for everyone. And, certainly they all have socialist policies, but similar how it would be inaccurate to define the US as entirely capitalist, socialism isn’t the only defining characteristic. China, for instance, is more strongly characterized by its fascism.

And the DPRK? By what measurement is this considered successful?

That said, I’m certainly not intimately familiar with all of them, and if socialism didn’t have positive successes in the world I wouldn’t support it.

I’ll bite. What successful socialist experiences are being denounced?
