Which experiences? It seems pretty clear---whether you are a TBM or not---that Joseph Smith did sometimes lie about his "experiences." The above quote does not specify whether the "experiences" in question have anything to do with Joseph Smith's prophethood. If fact, within the context of Tal's posts, I believe this is referring primarily to Joseph Smith's polygamous relationships.

Literally days after Pres. Keyes admitted to me that he knew that Joseph Smith had invented his stories (if you can believe it, he also admitted that Joseph Smith had "deliberately taken advantage" of girls in his polygamous adventures), he came over to the Salt Spring Island branch to release me from being the second counselor and Gospel Doctrine teacher as per my request.
Tal explicitly separates Joseph's "experiences" from his claims regarding Polygamy, a practice which began long after the First Vision and other related "experiences".
What the heck is the "Fist Vision"? Whatever it is, I don't think I like the sound of it. Anyways, I think one can doubt certain facets concerning Joseph Smith and yet still remain a TR-carrying member of the Church.

The darkside is always there, waiting for us to enter, waiting to enter us. Until next time...try to enjoy the daylight!"
