I think "humiliation ritual" is a hugely important concept to keep in mind these days: It has a lot of explanatory power for the stuff we're seeing in politics. (For example, televised Trump cabinet meetings where the brown-nosing is almost beyond parody.)
A cult will demand members do things to "fit in", especially things that have a cost ("prove your sincerity") and also things which alienate them from the non-group. The latter is a ratcheting trap, leading to: "We are your only home now, nobody else will have you."
It’s the psychological effect of a Mormon mission. Spend two years getting hate from all angles, teaching you just how good your home, family, and church are. Every ex-mormon I know contemplated suicide on their mission. Every practicing Mormon I know has a story about “their lowest point” and how actually it was a really really good thing if you think about it sideways
