I don’t blame what the Chinese commies did on Marx. The persecution of “landowners” was Mao’s doing and it was executed by local villagers who wanted to settle personal grudges and to prove that they are “revolutionary.”
Anyhoo, back to topic. Mao was a piece of garbage and one of the biggest dickheads in the history of the world. If Liu Shaoqi had come to power, I think the Chinese people would have been spared a few decades of suffering. But as usual, in power struggles, the more despotic person usually wins.
