As some of you mentioned here - JW's are taught and indoctrinated to be totally afraid of the real world. Due to WT indoctrination they are totally alienated from the real world and fearful of becoming too involved in it. They're told lies about how " evil " or " bad " non-JW's are ; when in reality there are MANY great people on this planet , many of them make much better friends than we had inside the JW cult.
Some exiting JW people become the WT Society's own self fulfilling prophecy. What I mean is if you are told enough times that " bad, terrible things " are going to happen to you once you leave the cult - then you are already leaning that way, or conditioned to think that only bad will happen if you leave the JW cult. Just like a teenager who gets told by abusive parents that " you're no good '' or " you never do anything right " , the teenager goes out and becomes as bad as the parents say because his failure is their prediction. So he lives up to the low expectations set by abusive parents. I think it's like that in the JW cult. It's like the book The Peter Principle where everybody rises to their own level of incompetence . It's predicted to happen from people's superiors, then they help it happen.
Doesn't have to be that way though. So many exiting JW's go back to the cult because they do not educate themselves about cult mind control. Even being disfellowshipped they are not aware that they were " mind controlled " and so never lose their belief system of the WT Society indoctrination as their brain neurotransmitters are only trained to think in " JW speak " . So then, they return back to the cult rinsing and repeating the cult abuse that happens to them. Kind of the way I see this. Unless a person totally loses the JW cult thinking- they are in danger of returning to familiar religious abuse
