I guess the flip side of the problem is that any real debate has been sidelined by a vocal minority (this thread is a microcosm of that) - and that's also bad.
There's definitely an extent to which a new generation can react against the defining characteristics of the one that went before - Andrew Doyle (in The New Puritans: How the Religion of Social Justice Captured the Western World) suggests this may be a way that we pull away from the more extreme social justice/witch hunts we're seeing lately.
But that could be a case of addressing the symptom rather than the cause. If a new generation rebels against, say, the idea that men can enter women's sports or that wearing blackface 15 years ago is somehow horribly offensive, the question is whether they'll just find other things horribly offensive and go after them Salem Witch-style, or whether they'll moderate their views overall. They're two very different things of course.
I do increasingly think that social media needs to be burned and destroyed though. And "Oh you can't regulate the internet" - but then I think we saw with Trump's TikTok ban that you can. And yes, I'm sure there's ways and means around those bans, but if banning X, Tumblr, TikTok or whatever ones are best gone after means interaction decreases by a significant amount, then that's got to be a win. And if some influencers or content creators lose their jobs, well in the greater scheme of things, so what?
(And yes, I'm aware of the Simpsons meme on the irony of appearing on social media in order to decry it, so don't bother pointing that out)
