Oregon was founded as a racist utopia.

71. Also worth remembering in this context (since Bundy is a Mormon):

the Mormon church taught that black skin was the "mark of Cain" (this was due to Brigham Young being a racist, so far as I can tell; Joseph Smith was an abolitionist).

And further:

The Great Compromise of 1850 allowed California into the Union as a free state while permitting Utah and New Mexico territories the option of deciding the issue by "popular sovereignty". In 1852, the Utah Territorial Legislature officially sanctioned slavery in Utah Territory. At that time, Brigham Young was governor, and the Utah Territorial Legislature was dominated by church leaders.[26] The Utah slavery law stipulated that slaves would be freed if their masters had sexual relations with them; attempted to take them from the territory against their will; or neglected to feed, clothe, or provide shelter to them. In addition, the law stipulated that slaves must receive schooling.

Utah was the only western state or territory that had slaves in 1850,[27] but slavery was never important economically in Utah, and there were fewer than 100 slaves in the territory.[5] In 1860, the census showed that 29 of the 59 black people in Utah Territory were slaves.[citation needed] When the American Civil War broke out in 1861, Utah sided with the Union, and slavery ended in 1862 when the United States Congress abolished slavery in the Utah Territory.
Racial restriction policy

Under the racial restrictions that lasted from the presidency of Brigham Young until 1978, persons with any black African ancestry could not hold the priesthood in the LDS Church and could not participate in most temple ordinances, including the endowment and celestial marriage. Black people were permitted to be members of the church, and to participate in some temple ordinances, such as baptism for the dead.[28]

The racial restriction policy was applied to black Africans, persons of black African descent, and any one with mixed race that included any black African ancestry. The policy was not applied to Native Americans, Hispanics, Melanesians, or Polynesians.
