Ideally, I think a social platform should lure radicalizing agents, then expose them to de-radicalizing ones, without exposing everyone else. Might be a hard task to achieve, but worth it.

You really think this works? I don’t. I just see them souring the atmosphere for everyone and attracting more mainstream users to their views.

We’ve seen in Holland how this worked out. The nazi party leader (who chanted “Less Moroccans”) won the elections by a landslide a month ago. There is a real danger of disenchanted mainstreamers being attracted to nazi propaganda in droves. We’re stuck with them now for 4 years (unless they manage to collapse on their own, which I do hope).
