We didn't see it because the WTS kept us busy reading and underlining and preaching and going to meetings... the idea is for the rank and file to never have enough time to stop and think and to ask questions. Plus, they hammer home the idea that the GB must be obeyed at all cost because they are the conduit to God via His Holy Spirit. To question them is to put your eternal reward in peril.
The one thing that all of those factors have in common? Pressure. They keep pressure on you, so that you are either too tired, too busy, or too scared to do anything but go along with it. That's why it can feel so oppressive to be a JW, and why it can feel so incredibly liberating to get away.
