Daryl Davis, yes his story was a big one, they slightly exaggerated just how effective he was but that’s okay. (Not everyone he befriended actually changed, humans have this weird world we can live in where we can hold contradictory ideas like, being a KKK member while having a black friend, that takes extra levels of involvement to try to change.)

For me, I mostly have flipped incels and their ilk, which come in many colors and backgrounds but the left has largely written off young men and boys in this situation because part of their schtick is to be as toxic and repulsive as possible as a way to validate and “prove” they don’t deserve love or good things in their life. They’re probably easier to flip than older, set in klansmen who have lived entire lives under one narrative, but the point remains - changing people is not some jedi skill that only “powerful, trained minds” can do, anyone can do it.
