"People of faith have been intimidated for simply exercising their democratic rights," President Thomas S. Monson and his two counselors in the church's governing First Presidency said in a statement. "These are not actions that are worthy of the democratic ideals of our nation. The end of a free and fair election should not be the beginning of a hostile response in America."

In the aftermath of the vote, opponents of Proposition 8 have picketed at LDS temples in Oakland and Westwood, Calif., and in New York. A Book of Mormon was set afire on the steps of a Colorado LDS chapel. Activists have called for boycotts of Mormon businesses such as Marriott International and Utah ski resorts.

LDS leaders called on "those who have honest disagreements on this issue to urge restraint upon the extreme actions of a few that are further polarizing our communities and urge them to act in a spirit of mutual respect and civility toward each other."

Also on Friday, leaders of Equality Utah, a gay-rights group, condemned hostile actions against The Church of Jesus Christ of Latter-day Saints, its members or buildings.

"We must engage in civil and peaceful expressions and conduct," executive director Mike Thompson said Friday. "There is no room for violence, vandalism or intimidation - Equality Utah objects to these acts."
