It's kind of complicated because we're having difficulty coming to an agreement on what socialism actually is/isn't.
Read "Das Kapital," and the "Communist Manifesto."
Envy rich, violent revolution, ownership of the factors of production by the state.
Totalitarian. USSR, PRC, pre-1989 East Germany, Cuba, No. Korea, Venuzuela, to start the list.
They don't deny being comminist, and it amazes me that people here waste time arguing with you over this.
In case you never learned, the East German subjects were held IN by a wall, called the "Berlin Wall."
Barbed wire, an area called "No-mans' land, whereby they might "make a run for it," but get gunned down.
East Germany was the model satellite of the Soviet Union, where your buddy Bernie honeymooned.
FYI the communists, call themselves "socialists."
