If you want to know what "Mormons" really believe (and not just what anti-Mormons say about us), you are better off using the resources here.
That's a misdirection to get people to avoid looking at (usually accurate) information about what Mormons don't want you to hear until you're in it deep enough you'll just swallow it, like God the Father being a former mere man who just got promoted for being a good little Mormon on his own home planet. At least you don't sue people over it.
But it doesn't even fit the link I provided, because unless you've dropped the Book of Mormon like you did polygamy and that curse of Cain thing, demonstrations of Smith's authorship are a perfectly appropriate answer to what you "really believe". You really believe it was written in ancient America, and you're really wrong. And the whole religion is exposed as a fraud, one of at least half a dozen ways anyone who's not already sold can easily see.
