Those examples of departing from left-canon (libertarian, “feminism-isn’t-perfect”, and “pua is often questionable in practice but not fundamentally bad from first principles”) are okay by me. I depart from the left-canon on those points myself and find the leftie moral outrage tactics on some of those fronts pretty annoying. All those things are still fundamentally egalitarian in values, just different in implementation. The homogeneity I was referring to was in egalitarianism and a certain type of emotional stance, a certain agreement concerning which first principles are valid and which goals are worthy, despite diversity in implementation.
(But, as ChristainKI pointed out, Moldbug himself was a commentator, and that predates me, so it’s true that the seed has always been there.)
