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.
I gotta have 10% of the "disengage" comments on this site.
Life is short. I can't imagine you being on your deathbed lamenting the fact that you routinely refused to go 12+ comments deep with someone who was being obstinate and arguing like its bloodsport.
You have a right to reclaim your peace.
