In view of the JW reactions on items such as the NGO thing, harbouring child molesters, it made me wonder about what it would take for the average JW to really grasp that the GB, the Org and lots of its doctrine is not what it claims to be.
Personally I've experienced that after a longwinded argument with an elder about the validity of the 1914 doctrine, he eventually agreed that it wasn't as solid as he thought and that it could be incorrect. Did he see the light (or its absence)? Interestingly enough, he immediately added that even if all this were true/untrue, it would not invalidate his loyalty to the Org & GB. After all they were only humans. Yech!
This reminded me of the apparently unlimited credit that fundamentalist leadership in general seems to have. It doesn't matter to the adherents what their leadership or their organisation is accused of, and it even doesn't matter whether such accusations are true or not. It doesn't matter if millions were stolen, thousands of people were killed, if innocents got convicted.
Interestingly enough it seems that only direct personal experience has the power of disrupting this. In my own case this happened, when I was repeatedly confronted with the blood issue since my wife cannot give birth in the regular way, and caesareans were compulsory. It felt so wrong inside when we signed the statements that we took full responsability for our decisions and their possible consequences whereas inside all of our conscience was screaming that we did NOT want to do this. I've read many a story here that shows the same: being in the org, some for a very long time, and only after personal confrontation with a particular issue, the scale is tipped.
Therefore I think that no issue raised can influence the loyalty of JWs to the GB & the Org on a large scale. Even if the GB, Bethel brass, or just local elders, would be catched with their pants down, in either moral, financial, legal, or any other wrongdoing, it doesn't really make a difference.
