The way the JW org works is to demand and expect total obedience to the cult masters.
It is not about truth or doctrine, the Org (like some other religions) is a mere business which goes about milking the gullible for their loyalty to the cult brand.This consists of a set of religious hypotheses invented by the governing body and presented as the exclusive set of divine truths-- but in reality doctrine is only a side show to the demand for brand loyalty.
All cult members are indoctrinated to have the highest expectation of complete conformity, this is the magic ingredient for a cult; everyone believing the same doctrine both as a prized mark of membership and as an (apparent) visible symbol of divine blessing. Therefore cult members are always alarmed at the smallest deviation from cult orthodoxy, the cult leaders however when challenged, become incandescent!
Were differing views permitted in the kh's the whole house of cards would instantly fall hence the perpetual propaganda to stave off real learning and making the case for believing only in the JW leadership. They must of course present their role as the only mediation between God and men, even if they publish otherwise.
Heresy then is the scourge of all cults!
Real knowledge thrives on argument and evidence. . . and cults thrive on ignorance and obedience.
