Yeah, that would definitely explain the hypersensitivity when it comes to any criticism of China or the USSR, valid or otherwise.
It still strikes me as counter-productive, though, as there are many people on Lemmy who have capitalism-critical views who could be persuaded to shift further left or become more interested in socialist causes. Banning them, or censoring them, or labelling them as idiotic liberals, only serves to undermine that endeavor. Socialism is dying fast enough in the west as it is.
