Tad R. Callister vs. Book of Mormon as "Inspired Fiction"

In his recent book, Callister seems to preclude the silly idea that the Book of Mormon is "inspired fiction," something a lot of liberal Mormons are arguing for (see here and here as just two examples of how preposterous this concept truly is; I would also add it is heretical):

Years ago my great-great grandfather Willard Richards picked up a copy of the Book of Mormon for the first time. He opened it to the center and read a few pages. He then declared: “That book was either written by God or the devil, and I am going to find out who wrote it.” He read it through twice in the next ten days and then declared: “The devil could not have written it—it must be from God.”
 That is the genius of the Book of Mormon—there is no middle ground. It is either the word of God as professed or it is a total fraud. This book does not merely claim to be a moral treatise or theological commentary or collection of insightful writings. Like the Bible, it claims to be the word of God---written on gold plates, delivered to Joseph by a heavenly angel an translated by the gift and power of God. If that story is true, then the Book of Mormon is the holy word of God, just as it claims to be; if not, it is a sophisticated but nonetheless diabolical hoax that needs to be rejected and exposed by every honest seeker of truth.
