Almost entirely different in their similarities but not in the method they are deployed.
Ok so with any such type of groups there is going to be good bits and bad bits. Might as well be a marriage. Because that is the basic trouble a relationship with such a group is, it has to be a HIGHER commitment than a marriage or even a relationship with a kid.

All things to make one persevere. Through the bad.
Here they differ, but only in some ways. Both keep secrets at randsom. Both make sure you know you will shunned no end if you think of leaving/back sliding.
