Ah, so just to clarify regarding insider / outsider terminology, I'm getting those terms from my research into religion in general and anthropology[1][2] rather than my own religion. But that made me chuckle a bit, the idea of a bunch of stepford wives chanting "outsider...outsider" and banishing someone. That is a familiar sort of stereotype to me as an insider, though many outsiders (again, not really my term, just a convenient abstraction) haven't usually seen such a mental concept through to completion via e.g. direct research, so it's still a shockingly common perception. I have some pretty hilarious anecdotes from encounters with those perceptions, but they are long to tell.

(BTW I'm happy to leave the non-scholarly use of terms like "outsider" to nation-states[3]...hehe)
