I heard the most interesting talk last year at the PA convention (Witnesses Now For Jesus) regarding the roles that JWs take...that basically there are three roles in a person's life, authority figure/parent, adult, and child. The Society becomes the authority figure, the JWs become the children and the THINKING, REASONING ADULT is suppressed, in fact destroyed. Hence, the JW becomes incapable of processing information or making decisions after awhile. They become completely subject to the whims of the Society as that supreme authority, relinquishing choice, thought...freedom...to become children again. Never ever allowed to grow up.
I will find that talk on tape and maybe make a trascript of it for here if anyone wants to read it. It sure shed a lot of light on their mentality.
