Being around conflict is awful.
We say that, and then I'm married to someone who did "debate" for fun in school. So it takes all kinds I guess! (But yes, no, I avoid it in every way I can.)

Regarding Facebook, I have an absolutely rigid separation between my professional and personal lives
This sounds very good and very healthy.

The whole point of this post was not to say 'my way is the best, and you should all copy me,' but to encourage people to do a kind of mental audit of the platforms they used, and ask themselves a) what they want to get out of said platforms, b) what, if anything was making them unhappy with said platforms, and c) what, if anything, could they do to remove those sources of unhappiness and make the platforms work for them. The answer to all these questions is going to vary from person to person.
Oh yeah, that's absolutely what I took away from it, too. That, and talking about it made me realize I could actually be even better at taking care of myself, and I went and added another dozen or so words to mute and turned off more retweets. It's already cut down on the Doom Content that was slinking through my existing filters, so thank you for spurring that! ♥
