This rant reminds me of how I felt at the end times of usenet in the mid-late 90s'. Usenet groups were awesome, until they were overrun by spammers and angry egos. Then I had to go. The problem that others have pointed out, if reasonable people fatigue out and leave, it self-sorts for the people that love to show how smart they are, or what big angry egos they have, and it spirals down from there. On one of your points, I have had the grand blessing of working with a number of people way smarter than me. And the nearly universal quality of really smart people is that they never point out how smart they are. Oh there are outliers that will constantly remind people of that fact, but by and large, the really (really) smart people never bring that up.
