If anything the psychological reactance to moderation is a disorder. Specifically it would be categorized as an externalizing disorder in the likes of ODD, CD, and ASP.
Being opposed to people like that isn't ODD. Its also something I think will be a problem in selling Mastodon - it's easier to justify a strict dictatorship in a small community when other choices are available, "just go somewhere else then?", than it is on big social media platforms where the expectation (at least in theory) is that they'll be somewhat balanced and impartial. No expects impartiality from a discord mod.
The perfect system of rules for moderation would be one you'd comfortably handle out to your ideological adversaries to enforce. If the outcome is still unfair, there's something wrong with the rules.
Something like "I cut, you choose".
I've also noticed that there's a group of people who absolutely hate to be told what to do. They have an innate psychological reactance toward it. It shows up in defiance to regulation, paying taxes, and yes even the idea that their internet posts could be moderated. It's a strange attractor in personality-space and they are very effective at using the mechanisms of social construction to pass their ideas off as the natural order.
