I didn’t know that. Thanks for sharing.
Yes, Marxism, though the granddaddy of Communism is distinct from it. It was modified by Lenin and Bolsheviks and then even more so under Stalin. Whereas Marx foresaw a time when the proletariat would no longer need the government, Stalin’s communism argued that the state would always be necessary to safeguard the movement against anti-revolutionary influences. But in reality this was but a foil to ensure his continued power. Communism then mutated again in China under Moa Zedong. Yet they all presented themselves as being true to Marx and Ingles original vision of communism.
So In someways it is redundant to talk about Communism or Marxism as if it is monolithic. So if someone says that CRT is ‘Marxist’ or ‘Communist’ it is probably worth asking which Marxism or Communism they are talking about.
