It is fair to point out that the FLDS is a lot closer to the Mormonism of Smith and Young than is the present mainstream LDS church. FTM, I believe even the FLDS prophets don't "marry" women who are already married to living husbands.
Kudos to the official LDS for moving away from their origins, but I do object to the way lie about them. A couple decades ago I went thru their welcome center/museum on Temple Square in SLC, and the main reason they gave (can't remember if it was the only one) for the hostility of the Missourians to the Saints was that they were opposed to slavery.
Sherman,
Your LDS history is bogus. Polygamy was not an open practice until the Saints entered Utah.
The Missouri troubles such as the Mormon extermination order of Gov. Boggs was pure religious bigotry and politics.
