The reason we are having this discussion is because I feel you've characterized me unfairly as "the Ex-Mormon who never really knew his own religion and had no reason to believe in the fringe theories he did". My goal is to support my case that I really was a mainstream Latter-day Saint before I lost my faith. So, you can use your apologetic arguments all you want for whatever idea you have about Mormonism, but if they aren't based clearly in the scriptures (which I studied a great deal), and if they were never taught widely in the Church, then why exactly did I err in not coming to the same understanding as you? I do not think you have any good evidence for why I was an atypical Mormon who was unjustified in believing in the things I did.

This here is an excellent point. I'm pretty sure all religions have "unofficial" doctrines; certainly it would fit my experience. Such doctrines have no bearing on the truth of the "official" doctrines, technically, but they are identified with the religion by believers and unbelievers alike.

That said, while I'm hardly an authority on Mormonism, I would guess your beliefs were more, well, strange than average - simply because your deconversion selects for unconvincing and dissonant beliefs.
