BizzyBee makes some very good points:
"...my knowledge was perverted to a narrow mindset of ridiculous beliefs."
"I think this commentator perhaps does not realize how bereft the average JW is of basic, objective Biblical knowlege. They only learn what supports a JW stance - nothing more. For most JWs the Bible is a framework of aluminum supports - to be bent as needed."
I didn't realize it when I was in, but the WT version of "bible" study is not about the bible at all. They have a predetermined and self-serving set of beliefs that they pull scriptures out of context to support. It is in no way a comprehensive, coherent understanding of the bible as a whole.
The JW knowledge gap in biblical understanding is huge. And yet, because they are not allowed to read religious information that isn't published by the WT, they don't even realize it. The problem is compounded when they call, unannounced, on people at the door who are not familiar with the bible and, compared to them, they feel like bible scholars because they can put two or three scriptures together in a five minute presentation.
Speaking from the experience of someone who pioneered for four years, I can attest to the fact that their knowledge is limited to a handful of scriptures on a select group of topics that are used to further the agenda of the WT, not promote true bible understanding. Even when the WT quotes scriptures in their books and magazines, they are twisted to serve the interests of the organization, not to help their followers understand the bible.
