A lot of Mormons roll through my area. I go to school with some. They're good people, but they obviously don't know much of what they truly believe. Most don't know anything about their actual theology besides the very basic beliefs, and even then most don't actually seem that confident in things like ascending to godhood or the cosmology of the religion., either. Even trying to shove all of the heresy that defies Christianity out of the way, I simply don't see how the Mormon church could be something to hold confidence in if I were a believer in the Book of Mormon.
Just for one showcase of the church's integrity, let's take the status of the Negro in the Mormon faith into consideration. First, the belief is that Africans were created out of people who remained neutral during a conflict that is written to have happened between Jesus and Lucifer while everyone was in the cosmos, turning the fence-sitters into Black people as punishment. This belief stays until the 1960s, when racial status reform and Civil Rights are underway in the U.S. Then, suddenly, the Prophet-President gets a notification from God, conveniently, that Blacks can now be in the Mormon priesthood, but they're still a cursed people. Some years later, in, if I'm recalling correctly, 1980, the president of the church said in an interview with Time magazine that the church now believed Blacks aren't of a lesser status and they actually did choose a side in the conflict, or, at least, they were on an equivalent level of valiance and honor to the other races. Currently, in our time, they just backtracked to the final extent a little while back, where not only do they deny their former beliefs ever happened (Jeffrey R. Holland PBS Interview in documentary "The Mormons", blabbers about how it was all just some inaccurate folktale) but they now say that Blacks are completely equal in the church and we're all just human. If I were a Mormon, I simply wouldn't be able to trust a church that completely flips around and then lies about the existence of a decently-important belief in the span of a few decades.
