"Please don't post shallow dismissals, especially of other people's work."

I wonder if an explicit expansion of that rule would help. Maybe in all caps. Saying "picking on grammar is a shallow dismissal".

Picking on LLM use is a shallow dismissal, too.

I don't believe that's always true, and I suspect it was left out of the guidelines deliberately, and I wish people receiving suggestions would stop interpreting it that way. Of course people suggesting grammar corrections and treating it like they just demolished and eviscerated your argument are part of the problem. But what about people out here just trying to help? Grammar is important, as it's the syntax of the programming language we all use with each other. People act as if bad grammar is something you're born with, and can't change. Like learning grammar is impossible, and those who don't bother should be a protected class. I'm just trying to help man. Or I was anyway, before I stopped. But if I'm trying to engage with someone's main point, it should be obvious. Whereas a quick grammar correction is just that. But it's a tangent, and not interesting (especially if you already know), and supposedly grammar is "not a technical topic" (despite daily use) so it ends up deemed a "low value comment" and gets downvoted to oblivion.
