Well, if GB2.0 really believes they have the truth (and I believe they do believe so) then they probably figure Jehovah will take care of it. If they grow, great, Jehovah is blessing them. If they shrink, ok, Jehovah is sifting them in preparation for the end; cleaning out his congregation.
It's always win win with them regardless of what occurs. That's because their mindset is that they are 100% without question.
It's like the end of the system. If things get bad then the end is around the corner; if things get good then the end is around the corner (peace & security). It's win win.
Interpretating the facts to fit a preconceived idea - what's the official term for that?
