> Is it possible to bring fringe groups back into the fold of peaceful civil discourse

It's not really "fringe" groups that are the issue here; it's "extreme" groups - no-one is calling for the flat earthers to be deplatformed, for example.

> Does censorship, even if justified, fuel anger and distrust

Probably but I'd guess only among the people who are already inclined that way already.

> the population must always have their speech regulated

If you put "some of" after "have", it's the situation we already have.

I believe deplatforming of flat earthers is already happening. Anyone who holds that position is not allowed on television and not allowed to run national tv ads and wouldn't be allowed to teach.

Here's Mark Sargent (King of Flat Earth) on reasonably high profile UK TV show less than a year ago.
