...and another one I just found which is particularly insightful:
I think this is another story about the destructive power of the internet echo chamber, where the asymmetry of one person vs. a mob of people who are in reality probably not all that engaged with the problem but nevertheless have enough engagement to send a nastygram or two creates a distributed denial of decorum attack that no single human being should be expected to deal with "nicely". Our ancient instinctive tribal signals of whether or not you are approved by the tribe, tuned for tribes of 150 people or so, receive a message that 15,000% of the tribe thinks you are a bad person, and our natural human response to that is a lot of stress at best (our ancient instincts tell us that eviction from the tribe is a bad thing , even though in practical terms eviction from this particular tribe won't be much of a problem at all in the modern world).

Especially the term "distributed denial of decorum attack".
(I'll try my hardest to make that my last submission this week. I went from a pre-actix-hullabaloo quote, to something of my own post-actix, to something of someone else's post-actix in such a short period of time, and the two "something of someone else's" ones are so different in what their focus is.)
