Those people came to those views somehow. I'd hope that a less radicalizing social media platform might move them away from those views. Finding common ground isn't just about figuring out where people currently agree, it's also an act of persuasion convincing people to change views to then-mutually shared views.

Wanting people dead or imprisoned simply for existing is the sort of inconsistent view that is likely easiest to change by moving people out of radicalized spaces...
