Al Sharpton is drawing fury over his denigration of the Mormon religion. While I have rarely met a Mormon I didn't like--on an individual basis you understand--if I believed that Joseph Smith was other than a 19th Century charlaton/con man/failed novelist then I would belong to the Mormon church. Actually, I believe he was a fraud, a deceiver, a libertine who wished to aggrandize himself at the expense of others, enjoy the fruits of other men's wives, and not have to toil very hard at all to make his living. He may have been interested in occult, i.e., (hidden, mystic) frou-frou and bric-a-brac from the late 18th Century, including Freemasonry or Illuminatus, and the Spiritualism movement.
None of this questions any Mormon belief in God. We cannot judge what is in a person's heart, now--can we? Judge not, lest we be judged. But, no rational person can hear the story of the authorship of the Book of Mormon, etc. and possibly believe it. Too much ink, real and virtual, has been wasted on this pathetic cult.
