BYU scientists have discovered how to remove the actual “Skin of Blackness” spoken of in the Book of Mormon (2 Nephi 5:21):
It’s hard to believe it is not satire. This article reports a study conducted by non-Mormon researcher attempting to understand how those who knew Mormons could distinguish them from non-Mormons based on a photo alone. The study found that “skin texture was the key indicator and determinant in distinguishing a Mormon from a non-Mormon”.
Because, apparently, this is now hard science, I suggest LDS immediately adopt a new interpretation of 2 Nephi 5:21 where the “skin of blackness” mention merely represents the lack of glow found on non-Mormon skin.
