Exactly! Marxists, anarchists, and leninists are alllies. Statist liberals on the other hand, whether they be social democratic corporate capitalists or stalinistic state capitalists, will always try to infiltrate and divide the communist movement.

It's just like this motte-and-bailey meme. The implied position is that the communists were wrong to tell the Americans to vote against fascism. The strong position, which is claimed to be the only position when it meets resistance, is that it's only against capitalist liberals.
