Deraj,
Not to speak for Logichopper here, but Smith's statement above, denying his practice of polygamy, was an outright LIE. At the time, here was merely attempting to save his owm butt. All you need to do is check the official lds church website at lds.org to verify his polygamous marriages. See here:

Just enter "Joseph Smith", and "Emma Hale" and click on the joseph smith name then provided to see a listing of all his wives. If someone within the lds church has convinced you that he did not practice polygamy, I would suggest you have been seriously "duped".
There was absolutely "NO" good reason for destroying the Nauvoo Prinitng Press. Even the governor of Illinois, Thomas Ford (an attorney himself) had said that Smith was wrong in its destruction (as has Dallin Oaks, current lds apostle and attorney).
Again, simply wrong again. Smith and others practiced polygamy in Illinois where it was, by statute, against the law. Go to the church website above and see for yourself that Smith was married to over 20 women. Then check out this photocopy of the 1833 Illinos statute prohibiting polygamy:

Perhaps you need to spend a little more time investigating the truth and facts of the lds church history!
