Part of the problem is a lot of people enjoy the anger.
The need to judge these people as "garbage" who simply aren't handling technology well is worthy of interest itself.
I'd never advocate something as obviously ridiculous as requiring ID to post on social media or the other sort of rubbish people outside of the tech industry come up with to deal with this problem, though I'd also point out that quitting Reddit did wonders for my mental health and generally made me less of an arse. Facebook strikes me as even worse, even more tuned towards pissing you off and preying on that human need to have the last word.
I made a dummy Twitter account to be logged into, that has no friends, just to be able to see links people post. There's no such thing as a dummy Facebook account and I've not looked at anything on Facebook since. The only account there is their shadow account on me, something Twitter has no interest in doing, and which Facebook must do so it can accurately assign accounts to every living human and avoid dummy/sockpuppet accounts.
