And there is also of neoliberals that pretend to be leftist, yes, so called "Radlibs".
Then there are leftists that accuse other leftists that aren't of their same brand of being liberals, for example MLs calling anarchists liberals because they admit markets, or anarchists calling MLs capitalists/liberals because of state capitalism and the DotP, and then MLs calling DemSocs liberals because they want to operate at least partiallty within "bourgeois democracy", etc...
It's a very North America thing, though.

These are the people doing the canceling (both to the left and the right of them). It's worth nothing the distinction as it's this group with the power.
Or, at least, approximately nobody; you can find examples of anything, but it's not like a significant thing.
