It's not about users being outraged about what
they can read.
"Those other people are idiots and will kill us all without some rules" is a basic human conceit. These people calling for censorship on Facebook don't want to see that stuff, sure, but way more importantly they want FB to censor so that other people CAN'T read that stuff.
They think that if they shout loud enough, they will get to decide what other, more gullible/radicalized/violent/whatever people are allowed to read.
It's really condescending nonsense to claim that you know better than another adult what they should be allowed to read.
Lots of really famous/successful people are thinking along these lines lately. It's quite popular amongst the "thought leadership" set to think that Facebook has some moral obligation to play publishing cop and shut down private groups where people say things they don't like, because people other than the ones calling for censorship are so gullible and malleable and childlike that they'll turn into a terrorist if they read enough about 5G or vaccines or antifa or whatever in private FB groups or something.
A handy example is John Gruber's recent post on the matter:

The correct answer to people being wrong is education, never censorship.
I defer, as always, to Heinlein:
> “Thing that got me was not her list of things she hated, since she was obviously crazy as a Cyborg, but fact that always somebody agreed with her prohibitions. Must be a yearning deep in human heart to stop other people from doing as they please. Rules, laws — always for other fellow. A murky part of us, something we had before we came down out of trees, and failed to shuck when we stood up. Because not one of those people said: "Please pass this so that I won't be able to do something I know I should stop." Nyet, tovarishchee, was always something they hated to see neighbors doing. Stop them "for their own good" — not because speaker claimed to be harmed by it.”
