Even when I was "in," the fact that the "Truth" could never be questioned always bothered me. Simple reasoning, "If the truth is the truth then no line of questioning can hurt it, so why be so worried about people questioning?"
This is why after I finally completely obliterated my faith in JW doctrine, and subsequently the Bible itself, turning to Science was the best thing ever because its foundation is basically, 'Question Everything!' which is what is so great, Science can be wrong, it'll admit it too, to be wrong is to learn, it's a wonderful foundation.
It just sucks so much that I didn't have this information through my teen years.
