The more ignorant you are, the better a JW you are, the higher your standing in the congregation.
I never bothered trying to understand the deeper things of the truth. I was known to be intelligent, so, people tried to interest me in it.
But, it was just so boring, all of it. Even then, I knew, whats the point of studying something if you can't question it?
What's the point of studying if you can only look at one source? This deep level of ignorance is why JW will never enter into a theological debate with anyone who actually knows anything about history/evolution.
