When you hear “authoritatian,” are you referring to states in general as instruments of authority, specific forms of states, or a specific metric of, say, representation? The reason Marxists say authoritarianism is a meaningless descriptor is because it doesn’t analyze what authority actually is in a way that is useful. I believe in a more unitary system of governance with democratic control by the working class. Some may say the democracy bit makes it non-authoritarian, some may say the unitary aspect makes it authoritarian, some may say the fact that it’s a state at all makes it authoritarian, and yet these are all equally valid/invalid usages of the term because it isn’t based on objectivity.
