It never ceases to amaze me, how contemptible and stupid the rank & file JWs are in the eyes of the GB. They view them as imbecilic children, with a faith so fragile that the merest glance at one piece of "apostate" literature, one furtive peek at computer porn, one hour's conversation with someone who doesn't worshipfully fawn over the GB, will cause it to irrevocably shatter into a million pieces.
That may be largely true, because a JW's faith really isn't based on anything but random interpretations of scripture by some dudes in Brooklyn. Sure, Witnesses can do "personal study", but all the personal study in the world doesn't matter if you aren't allowed to come to your own conclusion. I can just read the Watchtower and accept the Watcthtower answer or I could spend four hours going over the Bible and then, just to make sure I don't think about things in a different way, I still accept the Watchtower answer. So my faith isn't really based on anything.
When someone comes along with some faith or belief (which doesn't have to be religious, per se, it could be something scientific) that is based on something, it's not incredibly hard to sway me. So my only defense is to run away. Which is exactly what the Watchtower tells us to do.
