Well... China really isn't a communist country. And if you do read up on actual communism, you will find out that lots of the ideas have been incorporated into western societies. Maybe not in the US, probably more Rousseau than Marx. The earlier writings of Lenin and Rosa Luxemburgs struggle illustrate that really they had great ambitions, mostly very altruistic. What the Russians have turned that into... well I am not going into that. But China isn't really a socialist country at all if you ask me. It's lacking a lot of the original intentions when it comes to human rights and protection of workers. They also misinterpreted a lot of marx writings because of translation issues and cultural differences, apparently. Can't give concrete examples but I have been told in University that this is one of the causes why they perverted this whole thing.
Communism in it's purest form in my opinion manifested in Cuba right after the liberated it... right before castro went completely crazy and started murdering everyone who didn't fit. Ernesto Guevara was a humanist, then a rebell leader, and when the pressure got too big and his responsibilities became too large he turned into a war criminal. Castro never had any intentions of founding a socialist state, he just utilized the intense revolutionary potential. He really just wanted to become head of state himself and get rid of Batista (who was even more terrible as a leader, and a fascist fuck, pardon my language).
It all comes down to this: Great ideas of liberation always turn into violent carricatures of themselves if someone has too much power, be it a single leader or an oligarchic leadership instance of any kind. So keep reading about it, use their ideas, reinvent them all the time but: call it something else!!!!
