It’s more than a bit disingenuous to try to conflate “the progressive left”, as the term is generally understood, with “the far left” in the OP’s sense of pro-communist kneejerk “rejectionists”, or with the actual communist totalitarian dictators that you denounce in the last sentence of your post.
No, the modern progressive left that actually does have some influence in some institutions is not even close to the crankish fringe “far left” that the OP is complaning about, much less to any kind of brutal Marxist dictatorship. You’ll strain yourself hauling those goalposts around at that speed.
