Too bad, and I get what you're saying about the seeming levels of hostility. I dropped off for a while also as the clamor seemed just ridiculous, and actual discussion/debate, somewhat rancorous or not, seemed impossible to see beyond all of the just naked rage.
People are fired up right now on a lot of fronts during a really chaotic period. That is spilling over here.
It's been a long slog for a lot of people between ~March and here and a lot of it has been bad, bad stuff. People have died, they're still dying, the economy is taking a pounding, the cities are burning, violence is rising amidst social unrest stemming from the Virus and social conflict.
Worse, there is no certainty about when or how any of it ends, which messes with people's heads more I think than people realize. I've seen studies on how this type of uncertainty gnaws at people, increases stress levels beyond a given situation itself and manifests in a host of other ways.
People are worried, they're scared, they're drained, teetering financially, in a lot of cases they are angry from one perspective or another and they're lashing out.
It will pass. Hopefully relatively soon, as this basically sucks.
