Their temples are full of Masonic symbolism.
Their strict rules oppress women and children and subjugate them to lives of servitude to the men in the family.
The sects that break off because the mainstream Mormon church has denounced polygamy, practice abject slavery in regards to their wives and children.
Girls are married extremely young to old men, sometimes their uncles, cousins, and sometimes brothers, in these break-off cults.
These sects are also considered Mormons, still practicing the original law of polygamy. One break-off group, the Kingston family, believes that the females in their polygamous sect should only marry within the family to preserve the sect's "true bloodlines" so they have tons of kids born with extreme disability.
There is lots of in-fighting and bloodshed among these groups. Some go so far as to believe in "blood atonement" literally. This concept means:
In Mormonism, blood atonement is the controversial concept that there are certain sins to which the atonement of Jesus does not apply, and that before a Mormon who has committed these sins can achieve the highest degree of salvation, he or she must personally atone for the sin by "hav[ing] their blood spilt upon the ground, that the smoke thereof might ascend to heaven as an offering for their sins". [ 1 ] Blood atonement was to be voluntary by the sinner, but was contemplated as being mandatory in a theoretical theocracy (seeTheodemocracy) planned for the Utah Territory; it was to be carried out with love and compassion for the sinner, not out of vengeance. [ 2 ] The concept was first taught in the mid-1850s by the First Presidency of The Church of Jesus Christ of Latter-day Saints (LDS Church) during the Mormon Reformation when Brigham Young governed the Utah Territory as a near-theocracy. [citation needed] Though there was discussion about implementing the doctrine, there is no evidence that it was ever practiced by the Mormon leadership in their capacity as leaders of both church and state. [ 3 ] There is some evidence, however, suggesting that the doctrine was enforced by some Mormon individuals. [ 4 ] Writers have also argued that the doctrine contributed to a culture of violence that, combined with paranoia from the Church's long history of being persecuted, incited the Mountain Meadows massacre.

Very scary if you dig deeper into it. Is it a cult? I would shout an ecstatic YES! If you go to the XMormon sites and read the testimonials, as someone mentioned earlier, you could swear you were reading the stories of XJW people, or former Moonies, or former <cult> members' testimonials. The damage these high-control groups do to people's psyches is staggering and tragic.
