The White Horse Prophecy is a statement purported to have been made in 1843 by Joseph Smith, Jr., founder of the Latter Day Saint movement, regarding the future of the Latter Day Saints (Mormons) and the United States of America. The Latter Day Saints, according to the prophecy, would "go to the Rocky Mountains and ... be a great and mighty people", identified figuratively with the White Horse described in the Revelation of John. The prophecy further predicts that the United States Constitution will one day "hang like a thread" and will be saved "by the efforts of the White Horse".[1] PDF!!

Some have speculated, on the basis of the White Horse Prophecy, that Mormons expect the United States to eventually become a theocracy dominated by The Church of Jesus Christ of Latter-day Saints (LDS Church).[2] [[3]]Wolff, Elaine (October 17, 2007). "An American president".) The authenticity of the prophecy as a whole, which was not made public until long after Smith's death, is debated, and the leadership of the LDS Church has stated that "the so-called 'White Horse Prophecy' ... is not embraced as Church doctrine."[4] However, the belief that members of the LDS Church will one day need to take action to save the imperiled US Constitution has been attributed to Smith in several sources and has been discussed in an approving fashion by Brigham Young and other LDS leaders.

Several prominent Mormons have made statements related to the White Horse Prophecy. For instance, US presidential candidate Mitt Romney has said he considers the White Horse Prophecy to be a matter of "speculation and discussion by [LDS] church members" and "not official [LDS] church doctrine."[5]

The church has already been thoroughly discredited.

Any prayer is a form of self hypnosis. Some people just happen to believe the results that come from praying come from an outside force rather than simply reinforcing what they already want to believe.

I have read about these things, and I very honestly wish I did not know.

You're saying that the fact of polygamy (which is real) creates a shortage of mates for Muslim men (which isn't real). Places where there have been actual, reported, measured shortages of female mates for men?

1. America in the 19th century.
   
2. Australia in the 20th century.
   
3. China now.
   
   Those are real, measurable demographic phenomena that were witnessed and documented. The shortage of women in Muslim communities that you're describing has no documentation, because it is entirely fictional.

Not yet mentioned here, but this book was the most influential/informative to me, early in my transition from the church.
