The arguments here are off the mark. No long rebuttal needed. In fact, the response to the argument is shorter than the argument!
Critical question: How
illiterate was Joseph Smith Jr.?
Argument 1: For many Mormons, the 38 y. old
Joseph Smith was a theological genius who perceived and articulated the Plan of
Salvation in a way clearer than ever before
This is a straw-man.
We claim that God is a theological genius and that Joseph Smith received
revelations from Him.
Argument 2: Likewise, the 15-year old Joseph
Smith talked directly to God and was able to perceive that all the world’s
religions were in error
This has
absolutely nothing to do with literacy
