Say something negative about the GB and it is an immediate conversation stopper.
Not only an immediate conversation stopper but any dub (SPIMI, especially, within earshot) will be NOTIFYING/INFORMING the cong's BOEs to schedule a JC (within The Backroom or at that dub's residence) for a meeting/shepherding call. A member having doubts or not believing in the GB (2.0, particularly nowadays) is circumspect and considered an automatic apostate.
