Haha this is a great hypothetical comment!
The concreteness is helpful because I think my take is that, in general, writing something like this is emotionally exhausting (not to mention time consuming!) - especially so if you’ve got skin in the game and across your life you often come up across things like this to respond to and you keep having the pressure to force your feelings into a more acceptable format.
I reckon that crafting a message like that if I were upset about something could well take half a work day. And I’d have in my head all the being upset / being angry / being scared people on the forum would find me unreasonable / resentful that people might find me unreasonable / doubting myself the whole time. (Though I know plausibly that I’m in part just the describing the human condition there. Trying to do things is hard...!)
Overall, I think I’m just more worried than you that requiring comments to be too far in this direction has too much of a chilling effect on discourse and is too costly for the individuals involved. And it really just is a matter of degree here and what tradeoffs we’re willing to make.
(It makes me think it’d be an interesting excerise to write a number of hypothetical comments arrange them on a scale of how much they major on carefully explaining priors, caveating, communicating meta-level intention etc. and then see where we’d draw the line of acceptable / not!)
Thanks for writing this <3
