Having met most of the GB in the 1990's and 2000's and knew John Barr quite well I am convinced GB 1.0 were "Captives to a Concept" in that they believed 100% what they were doing was "the truth" hence why they kept in the background.
Conversely...whilst I am out and "see" GB 2.0 I am fairly convinced the majority of these are NOT like the GB of old and most, the majority, know that there are fundamental issues with their doctrines about "the end" and know there will be no end in their life time.
Jackson, Morris, Sanderson, Lett etc are in this bracket in my opinion.
The GB 2.0 are fundamentally different to the GB 1.0 of old and with that comes the belief that they are doing what is right...I think most on the GB 2.0 know some of it is bull.
So it will only be expected to see the same type of people appointed to the GB...either through copying the GB 2.0 or by being persuaded by the GB 2.0 that they qualify.
