Curiosity.

First and maybe only question is why their perspective changed, likely followed by getting a better understanding of what shaped their previous point of view…

“Glad you got out.”

My first question is “how long ago?” Because if I’m talking to a 30 year old who was a nazi at 20, then I’m not even suspicious. If it was much more recent, I’ll give them the benefit of the doubt but I’ll keep an eye on em. I don’t want people whose sympathies are changing from far right to far left to think that they will always be unwelcome, but I have to be wary of bad faith actors.

Driving people out because of their past isn’t fruitful. Someone used to have bigoted views but something made them change their mind, and they pushed hard enough to reform their life? Sounds like they wanted it, and are probably a changed person.

I know a few people like this. They help others leave similar situations. Great people doing important work.
