Left and Right are far too ill defined in a complicated political system to say authoritarianism is inherently incompatible with leftism. The very first left / right split was between two different groups of authoritarians with one side wanting to a government similar to the prior monarchy they had enjoyed, and the other side establishing a brutal dictatorship that killed 40,000 people for not hating the concept of monarchy enough. We need a more complicated metaphor than Left / Right because otherwise we get stuck in “no true Scotsman” debates about the many different spectrums of opinion someone can have. I agree the political compass sucks, I don’t agree its a tool to coopt leftness by right wingers. I think, as I said, what we need is to start normalizing more complicated spectrum tools like 8values and 9axes
