A good way to get the JWs doubting Corporation Leadership, is lower their morale in the Governing Body. Pointing out their stupidity, authoritarianism, delusions of grandure, and the depts of their wishful thinking bias done in such a way to overide watchtower inplanted prejudice.
Highlighting the phobias they have of apostates, their attitude toward children as nothing more that Corporation free labor denying them education and handing them over to pedofiles in the congregation be they elders or microphone handlelers.
Signs about doctrinal issues are a waste of time but I can't deny that some may benifit but that's just getting them out of one cult and making them pray for another. Anyway the bible is too full of shit to argue doctrine, much better to stay away from it and proceed to spend more time get oneself free from that residual mind control you're still clinging to that's based in the bible.
What are your ideas?
