You seem to be saying that the left, by definition, can't be in support of censorship et al. I don't see how this follows: in fact, I feel the exact same way about _liberals_. Individual negative rights are definitionally liberal values, while being on the left (or right) is obviously compatible with authoritarianism.

More empirically (though anecdotally), I happen to have a decent amount of exposure to honest-to-god self-identified Communists and left-anarchists, the type of people who talk about praxis and casually mention revolution, including a good handful in my social circles (though none that i'm extra-close with).

While they're dismissive of the prissier, more superficial forms of identity politics that many moderate leftists enjoy performing, they're often openly dismissive of liberal values. While their preference is for regulation, they're fully in support of forcing platforms to more heavily engage in banning and censorship of undesirables (or as you and they put it, "take responsibility" for making the platform "safe"), presumably as a strategic move.

I literally never claimed that. I said that it isn't the left pushing for censorship from corporations because the left almost entirely hates corporations more than liberals or the political right do.
