Also like how do you talk about liberalism and neoliberalism in a non confusing way while also claiming liberalism is left?

You make it clear with your audience that you’re talking about the “liberal” in the economic sense and not “liberal” in the philosophical sense. From a philosophical perspective is the difference between being pro changes (liberal) vs being against changes (conservative), and as the person previously mentioned, in this sense you could say there are conservative communists (want to follow Marx’s philosophy to the letter) and liberal communists (believe in the basic principles but feel some things need to be adjusted), just like there are liberal conservatives (believe in small/efficient State but individual freedoms) and conservative conservatives (social conservatives).
