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.
The argument is some people don't have the self control the extricate themselves from toxic conversations, so giving them a way to, albeit ungracefully, have the last word is the only way to stop them from stupidly getting their BP up over an angry internet shitfit.
I'll be honest, I don't think we should allow someone to be passive aggressive just to save them the stress. If they're going to rage over the internet they'll find something to be mad about eventually.
I mean, see my other comment for how I think we could improve thus
