Incidentally, I can't help wondering what would you have done if the Spirit had told you it was bunk ;)

I like to think I still would have debunked Mormonism in my own mind, but maybe not! That experience was extremely important to my deconversion process, because the only reason I believed in the LDS Church was because of the Spirit telling me the Book of Mormon was true and that Jesus Christ was my Savior. As soon as the Spirit told me something so contradictory as The God Delusion was true, my whole belief structure came crumbling down.
