Seeing just one side of a conversation with "Baptist Joshua on YouTube". From being in such a conversation with BJ once, I don't think he's had enough exposure to people outside his groups (ethnic, religious, political), so he says some pretty harsh things about outsiders.

I think he needs interaction with people who are outsiders, but not in a debate format. I'd say more of a "coming alongside to help" format, where he learns that members of $OUTSIDE_GROUP are just people like those inside his groups.
