I have read the King follett discourse. I went to an anti-Mormon web site that has a complete version of it. After reading it again, I saw no where of Smith claiming what you claim he said, that German was the most "perfect" language.The hermetic texts were translated to German when Joseph Smith Sr. was ten years old; in the late 1700s.
As you may or may not know, Joseph Smith Jr.(the first Mormon Prophet) claimed that German was the most "perfect" language (circa 1840). He made this statement while delivering his well known "King Follett" discourse.
So if you can't get correct what smith actually said, how many other "mistakes" have you made in what you claim is true? Hmm?
