Not sure where your 'rule of elites' angle into play here, good faith and rationality are things that are debated and roughly agreed upon within societies and institutions (perhaps I do agree with your statement "These are emergent properties that come from free speech"). My point(s) were explicitly that: - Cancellation often happens with ill intent from bad actors: partisan, one sided policies that don't apply to 'their side'. You'll see little in the way of due process, benefit of the doubt / chairitable intepretation. - That combined with reactionism and little desire to combat base stereotypes, makes an easily weaponizable army.
I found Jonathan Haidt's description of cancel culture to be on the mark. It's all about intimidation: Not just for the one being cancelled, but of everyone else who's watching. It's a prelude to a wave of self-censorship.
