I'm just middle aged and lost all energy for unproductive discussions. The second another poster posts something genuinely hostile, like "touch grass" kinda shit, I'm just done talking. Also if we're six comments in and the other guy won't even admit to being wrong to the thing he said on comment one, despite me doing twenty minutes of research to prove conclusively that he's wrong, I don't want to waste another second of my life on him.

every time it’s used, it was established as a way for moderators to enforce disengagement. If someone isn’t harassing you, you can just not reply. That’s always fine and okay. Unless you’re forming personal relationships with people here somehow, the person ideally won’t even notice because they’ll have a handful of other threads they’ve commented on anyway.
