Is that the sound of things falling into place?
Good for you yarma! Cults are much easier to recognise from the outside. Since you were brought up in one how were you to know any different? Might be even harder than for a signed up cult member who at least knew life from before their cult involvement.
I sense your excitement at making sense of things. We here at least can appreciate that. But I'm guessing your mother and other premies you know won't be so pleased. The notion that she's been barking up the wrong tree for 50 years won't be made any more palatable because it happens to be the truth. I have a brother that's been involved just as long. He hasn't spoken to me in 10 years ( perhaps because I post here?) but if we were in a room together I doubt I'd mention the cult. That sleeping dog can lie.
Wishing you well in assimilating your discoveries.
