Welcome, William:
The short answer, as so many here have already said, is yes, you will be expected to believe 100% of what JWs teach. This is not an organization that tolerates questions from its baptized members, and quickly labels any such questioning as "murmuring," "complaining," and "rebelling." This is a high-control, strictly hierarchial organization that governs from the top down, and as ordinary rank-and-file publishers, the vast majority of JWs, including ALL women, are expected to obey without questioning. In order to maintain such tight control, information is strictly controlled and members are strongly discouraged from purusing much in the way of third-party research, such research being viewed as coming from Satan's world. Unless, of course, it happens to correlate with JW doctrine, and then it's seen as proof of the "Truth."
I am baptized, born-in, and currently inactive, as my conscience does not allow me to promulgate ideas I knew to be incorrect. Best wishes to you and please keep us up to date on how things go...
