Yes, Engels does a pretty good job of explaining why “authoritarian” complaints are usually explained purely by vibes.
He mostly explained how he actually didn’t really have a proper grasp of what authority actually means. He conflated them with a lot of things without actually making sense. I’m surprised why “On authority” is so widely known.
Let me guess, you’ve read “The problems with on authority”, but haven’t read "A Marxist Response to “The problems with on authority” " ?

He has a great grasp on how often Anarchists operate mainly on vibes, even if in practice when they get into power they still implement some form of authoritarianism, such as the labor camps in Revolutionary Catalonia.
Sorry, but claiming that just shows that someone didn’t engage at all with anarchist theory.
Edit - addendum: even if this wasn’t true back then in Engel’s days: Still quoting him today ignores all that anarchist theory on power that happened since then.
