Hellothere: Sorry but I do think they believe what they write.
I get what you are saying, and a part of me thinks you are right. But it is also difficult to comprehend-- these are men who know about the false predictions and all of the strange things that were written and said in the past. They have to know, I cannot imagine how they are not aware of the organization's past. How can they know these things and still feel they are in the right?
And yet, I have known men who were in for decades and believed devoutly, even though I know that they had to know of that history (because some had even lived it!). The way our minds can wall off thoughts and ideas that make us uncomfortable is as amazing as it is troubling.
