I agree with the sentiment in general, but wrt China in particular, how socialist is it really? Yes, it's a one-party authoritarian state that calls itself communist, largely due to historical reasons. But the contemporary Chinese economy seems very much to be a market economy. Albeit one with a lot of state intervention typical of authoritarian regimes, but that doesn't make it socialist much less communist.
Well indeed. What does that mean? Nobody seems to be interested in any kind of intellectual accuracy or coherence, they just want to use "socialism bad" as a thought-terminating cliche.
