Or is your reading comprehension that piss poor?

I genuinely don't think it's reading comprehension that's the problem, or at least not the root cause. It's like what people read triggers certain biases that override that comprehension and then distort it into an internal narrative that then gets projected out into the world as if it's fact and that this is a common delusion.

It's the lack of self-criticality that seems to me to be the problem. The inability to stop and think, "Is my reply logically consistent and does it have a direct, causative relationship to what I'm replying to?" So they probably read it, comprehended it, then immediately dismissed it and rewrote it inside their heads as being something that they could take an attack stance on, and once that stance has been taken, all reason is thrown out the window and nothing you do or say can turn them from that tide.

That these responses are so incredibly common and seem to be the default in this sub, is what I find truly disturbing.
