Cults....Religions.....if you build one, the people will come.
It seems to me that depressed desperate people ( possibly our parents or grandparents?) were the first ones to get involved in these religion(s) and cults. They spent hours and hours steeping themselves in it until everything sounds beleivable. They get totally caught up in it and they got their children caught up in it. Pretty soon those kids grew up and after all that time, it seemd normal to them and they continued on with it. For others, it meant they had to leave and suffer the consequence of having to start over with no support system and few social skills. The religions that make it, grow and get populated by the children of the original depressed recruits and sometimes the occasional depressed new recruit. Those whose life is going well don't tend to join cults.
I think that's how most religions got started in the first place because let's face it, they're all pretty wierd. JW's are a relatively new religion and some really old ones can claim to know or have relatives who knew the original founders of it. Who knows what Charles Taze Russel and those ones from the early days, were like in real life. If the internet had existed back then, they might have been exposed as the charlatans they really were, before they could have gained enough ground to become stable and take on a life of its own.
Hopefully this guy will have some sort of crack up in a few years or be exposed as a lunatic before too many of those children grow up in that environment.
