Women are treated as inferiors in the LDS church. Polygamy would have continued for generations without the intervention of the federal government. The LDS church spends millions of dollars to support continued discrimination against gays.
Until 1978 blacks could not hold the priesthood in the LDS church. Some quotes from the "Book of Mormon": 2 Nephi 5:21-23:
"And he had caused the cursing to come upon them, yea, even a sore cursing, because of their iniquity. For behold, they had hardened their hearts against him, that they had become like unto a flint; wherefore, as they were white, and exceedingly fair and delightsome, that they might not be enticing unto my people the Lord God did cause a skin of blackness to come upon them."
"And thus saith the Lord God: I will cause that they shall be loathsome unto thy people, save they shall repent of their iniquities."
"And cursed shall be the seed of him that mixeth with their seed; for they shall be cursed even with the same cursing. And the Lord spake it, and it was done."
"And because of their cursing which was upon them they did become an idle people, full of mischief and subtlety, and did seek in the wilderness for beasts of prey."
3 Nephi 2:15 reads:
"And their curse was taken from them, and their skin became white like unto the Nephites."
Mormon leader ("Elder") Mark E Peterson:
"The reason that one would lose his blessings by marrying a Negro is due to the restriction placed upon them. 'No person having the least particle of Negro blood can hold the Priesthood' (Brigham Young). It does not matter if they are one-sixth Negro or one-hundred and sixth, the curse of no Priesthood is the same. If an individual who is entitled to the Priesthood marries a Negro, the Lord has decreed that only spirits who are not eligible for the Priesthood will come to that marriage as children. To intermarry with a Negro is to forfeit a 'Nation of Priesthood holders'...."
"If that Negro is faithful all his days, he can and will enter the celestial kingdom. He will go there as a servant, but he will get celestial glory."
Etc etc.
Notwithstanding the cowardly, brain-dead, head-in-the-sand intellectual compartmentalization others are advocating here, I doubt any of us would be commending the SEO efforts of other organizations that have the kind of sordid history and unfortunate social passions the LDS church has had...and isn't shy about paying for.
