Speaking as someone who was raised as a witness... I get that the indoctrination effects even adults, but think of how that indoctrination effects you when you heard it through all your formative years. When I left there was a long period of time when I would have to leave the room if a special news bulletin came on the TV because I would get physically ill... yes, I would literally get sick to my stomach because no matter how much I didn't believe the witnesses were right I just knew that news bulletin would be telling me that all religion was now outlawed and it would be too late for me. I had dreams of jehovah chasing me with mudslides at armageddon well into my early twenties. Then you have to look at social development. The 'I am better than everyone' attitude is a hard thing to shake when you grow up with it. It is an almost continual battle to humble myself when situations call for it. And I still don't do well in social situations. I was never allowed to have friends outside the witnesses and there weren't that many options within the witnesses. I am very blunt and abrasive and often misinterpereted because I just don't get, or don't care to get, all the subtleties of normal, healthy social interactions.
Now, don't get me wrong, there were things I got from growing up as a witness... I am not swayed by peer pressure and don't have a problem standing up for a cause I believe in despite what the authority figure in the situation thinks. I have the strength of character to not be overly concerned with those who don't accept me for who I am. I make no judgements on the basis of race. I am honest to a fault. But, honestly, I think there would be better ways for me to have learned those things growing up than as a witness. Also, those are not things that every kid raised as a witness takes from the experience, either, so it's no guarantee.
Here's the other difference. Growing up as a witness I knew my Dad's love was, to a degree, conditional. Yes, yes, he loves me no matter what, but I knew that the relationship would be damaged, strained, and difficult if I ever left... despite the fact that I was never baptised. Those who convert into the religion know that their families love them no matter what, assuming it is a normal, healthy relationship. Perhaps their families don't agree with their decision to join the witnesses, but there is no shunning or such. And if a convert leaves they have that family and old friends to fall back on... a built in parachute for the jump back into the world. There is always the knowledge there that they have something or someone to fall back on. If a witness kid messes up they don't have that security that those they love and care about will *always* be there for them. And isn't that the duty of all parents? To be a safe haven for their children no matter what? Witness kids do not have that, instead they know if they mess up not only will their parents turn their backs on them "out of love" but jehovah will destroy them.
When I speak with someone who doesn't understand what it is to grow up as a witness this is one of the things I say to give them an idea: You know when you were a kid and you would be scared of the monster under the bed. And your mom or dad would come in and tell you the monster wasn't real, wasn't going to hurt you, and checked all the places the monster might hide just to reassure you that the monster wasn't there? Jehovah was my monster, and my dad told me constantly just how real my monster was. That fear is what it is to grow up as a witness... at least it was for me and for many others I have spoken with.
