I understand where you’re coming from and agree in principle; however, I stated that the issue is with common parlance, which very much does include authoritarians among leftists. The Wikipedia article you linked even says so under the subsection: Types, where it includes Maoism. Perhaps I should stop referring to such as leftists so as not to normalize that perception, but it is already so and would make having a conversation with people far more difficult if I were speaking from a reference point that most people don’t share.
SML 1 was my first game, and I love it dearly, but SML 2 is objectively better in almost every way.
