(1) I admire your energy, but sir/ma'am this is a Wendy's.
(2) I am very confused that you thought I was talking about tolerance-of-intolerance types of conversations, when I was more intending to say "I don't need to write an essay responding to technical comments even if I think I have a different angle of technical insight than the commenter, and not worrying about that can be freeing."
(3) For posts like the ones you mention that do trigger the "tolerance of intolerance" paradox, sometimes the very "feeding" of a troll is what makes them feel part of a community, and refusing to engage can indeed be the right way to handle those messages, and the morally correct thing to do.
(4) Not to mention that there are many ways to effect change that are higher-leverage, and less wearing on one's limited stamina, than replying to every disagreeable comment on the internet.
(5) I'm not proud that I've written a five-point answer here. It has not sparked joy, but I've written one anyways. Do what sparks joy, and consider my reply here a cautionary tale.
