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.
You're not getting paid for this. You're not even a volunteer. You're doing this (presumably) for recreational purposes--because it makes you feel good. You don't owe anyone anything. Disengage when you're not getting what you want out of it.
