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.
Nah, i wouldn't even comment that i disengage, i'd just ignore it.
People aren't always gonna be online and able to reply to stuff, much less have longer discussions and i think most people understand that. sometimes i feel bad for not replying to people who replied to me because i went offline for a couple of days and didn't see it, but that's just part of communicating on a site like this.
