Really, I just provided eyewitness accounts of the towns people asking JS to be quiet about Polygamy.
Secrecy, Polygamy, and Threats of Violence against the Saints
One prominent source on Mormon polygamy indicates that secrecy was the only feasible tactic for establishing polygamy in the nineteenth-century American west. Richard Van Wagoner notes both the illegality of polygamous marriage and the social opposition to it:
Polygamy, a criminal act under the 1833 Illinois Anti-bigamy Laws, was so unacceptable to monogamous nineteenth-century American society that Joseph could introduce it only in absolute secrecy.54
The civil disobedience perspective is again important, but the extreme taboo of polygamy to Joseph’s contemporaries–understandable given the Victorian sensibilities of nineteenth-century America–points to another difficulty which we have not yet considered.
Emma Smith (no fan of polygamy) insisted that Joseph and Hyrum’s murder was due to polygamy.55 Even so, Emma’s assertion must be taken with a grain of salt–her opposition to polygamy later led her to deny that her husband had ever practiced it at all, which makes it difficult for plural marriage to have been the cause of his murder, as she initially claimed.56 Yet, there can be no doubt that Joseph knew that he risked his life–and lives of his followers–in preaching or practicing polygamy. Sarah M. Kimball recalled Joseph’s attitude in 1842:
"He [Joseph] said in teaching this [polygamy] he realized that he jeopardized his life; but God had revealed it to him many years before as a privilege with a blessing, now God had revealed it again and instructed him to teach it with commandment as the Church could travel (progress) no farther without the introduction of this principle."57
Louisa Beaman likewise reported that Joseph said, "In revealing this to you, I have placed my life in your hands, therefore do not in an evil hour betray me to my enemies."58 Jane Richards recalled that Joseph’s revelation on plural marriage “should [be]…without publicity at this time,” since "mob spirit was already quite excited."59
Polygamy certainly did not cause all the persecution which the Saints endured at Nauvoo. As Wilford Woodruff noted, they had suffered persecution before polygamy was an issue at all:
“Why,” says the world, “you profess to believe in polygamy, and that is why you are persecuted.” No, you are mistaken about that. The worst persecution this Church ever endured was before polygamy was revealed to the Church. We have had more prosperity since we carried out that law, and endeavored to fulfill it according to the command of God, than we ever had as a people before.60
This was not mere wishful thinking on Wilford Woodruff’s part. In 1877, J.H. Beadle, participant in the publication of much anti-Mormon material during the Utah period,61 wrote:
the Mormons had more trouble with the world before they adopted polygamy than since…Polygamy will do for a scapegoat, but the trouble is far more radical than that.62
Despite this, polygamy did certainly help set off the powder-keg that was Nauvoo. When Hyrum Smith read the revelation on plural marriage to the Nauvoo stake presidency and high council, William Marks, Austin Cowles, and Leonard Sobey refused to support it.63 William Law, his brother Wilson, and others used the Nauvoo Expositor issue of 7 June 1844 to detail Joseph’s polygamous practices, and to charge him with various crimes, labeling him a "blood thirsty and murderous…demon…in human shape"64 and "a sycophant, whose attempt for power find no parallel in history… one of the blackest and basest scoundrels that has appeared upon the stage of human existence since the days of Nero, and Caligula."
