While you still were JWs did any doubting JW ever try to talk to you about the flaws of the org and instil in you some doubt?
Someone had told me that he didn't believe the GB members were straight and honest people that many of their ideas were wrong and that they had a secret agenda to pursue beyond the one they publicly proclaimed.
At the time I thought he may be right since they seemed to control everything and didn't allow anyone to contribute even the (so called) anointed. I later found out he was right.
