I have a different perspective.
Most JW's have an unrealistic concept of the "truth", the GB, elders, Bethel, etc. and why wouldn't they? This is the picture painted by the org.
But when we start to see the flaws it dashes the picture we have built up in our minds. I have no doubt that many things are wrong, some of which are very serious. I've read this board for many years and observed many families break up over this. Many others lose faith in God and the Bible leaving them without any hope for the future except rotting in the ground. Others run back to Christendom and happily celebrate all the holidays ASAP.
Sometimes I can hardly contain my revulsion at some of the things being taught and also find it very hard to go in field service. I no longer serve as an elder but still comment selectively. I don't want to break up my family nor lose the faith that remains in me. I also look to the Bible and see that I was stupid to have such high expectations of other humans. True enough that they want us to have that picture but it is a standard that is impossible to achieve. All thru the Bible we read of how bad humans are when they turn into leaders. WT leadership is no exception. So I stay a JW even though I disagree with a number of things and have had my perception of the organization adjusted to be more realistic.
Feel free to PM me if you wish. I refrain from getting into long arguments on here anymore.
