Especially when you realize its initial motivation.
What a lot of people don't realize is that Joseph Smith came out with the first published Book of Mormon in 1830. In there, several passages exist (including the Book of Jacob) where polygamy is spoken of very negatively -- even being labeled an "abomination."
A few summers ago, Lds apologists were meeting and one presenter admitted that polygamy as a Mormon institution began in 1831. 1831! Only one year after the Book of Mormon had denounced polygamy repeatedly!
Why the abrupt u-turn?
Because a 16 yo neighbor girl -- Smith's first polygamous lover -- named Fanny Alger had begun living in the Smith household as a sort of "maid" to earn her keep.
Joseph Smith only lived for 13 more years. And by the time we get to the 1841-1844 years, we have in rapid succession...
* Both Joseph Smith and his brother Hyrum openly denying -- and in print -- that polygamy was being practiced in Nauvoo, IL...
* By 1842, Smith is adding a "wife" on about an average of every month. Every month! (How did he have the time to court a woman, let alone add her to the wife roster, run a church, be a city mayor, and attend to previous added wives?)
* Not only was he adding a wife on the average of every month over a two-year period in the 1840s, but almost half of them in a given time period (11) were still married to their husbands! [Some of these husbands just happened to have been shipped out as "missionaries"...and btw, many other women & their husbands rejected Smith's untoward advances for similar arrangements...Orson Pratt and his wife, for example. Heber C. Kimball and his wife as another example. Instead Heber gave Smith his 14-year-old daughter!
You can't get more willingly blind Mormons that those who refuse to look at this track record of Smith! They've essentially told the world, go ahead and poke out my spiritual eyes!
