You’re failing to understand that the interest of “tankies” is in democracy being enforced by a proletarian control of the state. The copypastas you were getting were poor communication but they had a point.
The fact that you’re comfortably arguing in parallel with blatant neoliberals should give you pause, or are you going to tell me they are less of a concern because they are not “authoritarian,” because when people are richer than God and control immense swaths of production and politicians themselves while skirting regulation to fuck over the workers their class made desperate by enclosing the commons, that is not “authoritarian”? This whole thing seems kind of bankrupt to me as far as political theory goes. The mechanisms of control are diffused by various means into the economy and divided among the public/private sector, but if the private sector owns the public sector (and it does) you’ve got a class of kings who only half-pretend they aren’t (Zuck deliberately getting that Caesar haircut is a tell).
