I'm the same as Jimmy Young and LHG - it was the 1995 generation change that first opened my eyes.
The Watchtower mag that announced that change also had an article about child abuse. The article said something like 'if a child says Brother Creep abused him/her but Brother Creep denies it, then there's nothing you can do. You just have to wait on Jehovah.'
The generation change made no sense. It only made sense if you considered the view that the Governing Body didn't know what the hell they were talking about and were just making it all up as they go along.
And the child abuse article - I was 'in' but I could see this was wrong.
I stayed with the JWs for another 11 years because 'where would we go?', etc.
