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 can do that IRL too. Don't like something? Just leave. As a BJJ coach, whenever I'm teaching about double tapping to submit I go "it doesn't matter if you don't feel like you had a submission, if they get bored and decide karate is better, you just let go and let them go out the door"
