@ Garybus and PP - surely you don't think it is just that easy? It has many more layers that just a simple "get over it". I don't think people would mind being shunned by "some jerk" but for most it is family and what they thought were friends. Can be pretty hard to reconcile that kind of emotion and still come out sane.
It's never a case of a simple "get over it" and I'd never suggest it was. However, to stay in a cult because you fear losing contact with people who only stay in contact with you because you're seen to be part of their cult is surely counter-productive and in the long-term much more damaging that simply leaving.
It's especially disturbing that some willingly choose to stay in the cult, and live with a sense of foreboding due to the cult's rules and a sense of looking over one's shoulder due to the cult's elders, because they fear family members not speaking to them ever again. Not only are they subjecting themselves to a lifestyle restricted and shaped by a set of doctrines they don't believe in, but even worse, those doctrines are formulated from a fantastical book they don't believe in either!
