The Book of Mormon. Someone literally paid me to read it. It is so glaringly obvious that it's tall tales by Joseph Smith it hurt to read from the cringe. And it was so dark, too! Most memorably the section titled "Doctrine & Covenants." In chapter 132, verse 54, Joseph says Emma Smith, his ninth wife, would be destroyed by god, and her entire family destroyed for good measure, if she refused to sleep with him.
I don't understand how Mormons can be so gullible, and in believing all of it, how they can believe a deity that threatens women for refusing to sleep with a sexual predator can be a deity they want to worship. It makes me sad to think about.
