I'd hazard a guess to say that actual Bolsheviks would be appalled by American liberals, many of whom engage in conspicuous consumption and are vastly more interested in the appearance of affecting change than in the actual work required to make it happen.
There is a vast difference between American liberals and left-wing politics.
The Bolsheviks still had the complete case of "missing the goddamned point" and beligerence such that they put totaltiarians in power. I am afraid that "more interested in the appearance of change" applied to them as well. Hell they fit the exact same framework of "fanatical hatred for those with more minute policy distinctions". Their most damning flaw was that they were in the end more interested in killing anyone better off as a scapegoat and dogma policing than them than doing anything to make life better.
They aren't the same (thank god - the original Bolsheviks were psychotics!) but plenty of resemblences. There is still the absurd supply-and-demand denialism common to both the area and the self-proclaimed left-wing. Then there is the whole "fight new higher density housing as gentrification" making everyone worse off as the supply doesn't rise but rents do anyway.
