A good book on the subject is Mormonism Unmasked, by R. Philip Roberts.
Or, that you and yours do not agree with it. Or, that the contents are quite eye-opening. Or, that it would be highly controversial to true believers, perhaps even shaking their trust and faith in what they have been told. Or........
Funny the garbage is direct source citations and quotations from the founders of Mormonism, from sacred scripture like the Book of Mormon, Doctrine & Covenants, Pearl of Great Price, from LDS Prophets, Presidents, and so on..........Got to say WOW here. If their teachings are now 'garbage' why are you LDS?
