I agree with LG, if a born-in leaves as a teenager, they seem to assimilate better into the normal world. The longer they are in, the harder it is to start over and buck the system. By the way, I never look to see the ratings of movies before I see them. I just go by interest.
I am a convert and I think having a "normal" life before becoming a witness is a nice bridge to cross back over on. I was attracted to the idea of an earthly paradise and wondering how to raise my child when I joined the madness. Instant friends you could trust, instant friends wherever you went, never going to die, what's not to like?
I also had a grounding in another religion before I joined and that actually helped me to leave. As I realized that the promises the witnesses made were false, it was easy to pick out the twisting of the scriptures they engaged in.
The hardest part, as anyone can see on here, is the turmoil within families that leaving causes. This can happen to born-ins and converts. The saddest ones are those that leave, yet still believe it all. They are in a state of constant turmoil.
