I could go on for a long while about this if you like but the short version is that they’ve been convinced that destroying US hegemony in any respect is a net world positive and a step towards true communism. If the slave king Fallowind were to rise up in Missouri and lobotomize every man woman and child, there would still be voices of approval. Hyperbole aside, check lemmygrad after any atrocity that negatively impacts the US to see what I mean.
But that… is so obviously the wrong way to think about communism… wtf is wrong with these people? Imperialism is okay if it bothers the worst imperialist?
Their community is relatively small and thus easily influenced towards relevant novel ideas, so many suspect Russia/China boosted divisive trains of thought. Radicalized communists are geopolitical positives. I just think tankies are loonies.
