You are correct Room 215 in that there are indeed many liberally minded JWs - I was one. The problem is that all the time these ones mitigate for the organisation's faults and allow the cognitive dissonance to work against their better judgement they are locked into the basic control mechanisms that prevent one from becoming mentally free.
It's almost worse for me that my wife remains in this state as if she were an uber loyal fundamentalist as I could feel less aggrieved at what is essentially wilful ignorance. She is quite capable of grasping the issues but cannot get over the CD. I can't blame her as she is as much of a victim of circumstance as I was but it actually requires even more CD when you have a more "balanced" worldview since there is less of what is normal to most people that you outright reject.
