in part, over belief in plural marriage. Political usage LDS Church membership was made up predominantly of Democrats until the early 1900s, possibly due to anti-Mormon positions held by the Republican party during the latter half of the 19th Century. However, the church's conservative positions on social issues such as sexuality, drug use, traditional family values, and the role of religion in government caused large numbers of previously Democratic Latter-day Saints to shift to the Republican Party by the late 1970s. In the late 1970s and early 1980s the LDS church took a stand against the Equal Rights Amendment, and again increased the population's participation in the Republican party. At that time, many members who were registered Democrats were called "Jack Mormons", not as a negative term, but to distinguish them as traditional liberal Democrats. Because of the negative connotation of the term's modern context, this usage was short-lived. An alternative theory and contemporary usage holds that the term refers to a person who is a Mormon in "name only" (as in having a common Mormon surname) as though the "Mormon" label were nothing but a surname to this individual. The term was made popular by heavyweight champion William Harrison "Jack" Dempsey, born in Manassa, Colorado, on June 24, 1895. During the 1920s the greatest American sports hero of the day was undoubtedly Babe Ruth; his closest rival was Dempsey, a tough heavyweight boxer from the mining West. Around 1880 an LDS Church missionary converted Dempsey's parents and they moved to the Mormon village of Manassa, Colorado. While his father parted ways with the church, his mother remained a devoted member. Dempsey would write, "I'm proud to be a Mormon. And ashamed to be the Jack Mormon that I am." Change in terminology The term is now used to describe a baptized member of the LDS Church who rarely or never practices the religion, but is still friendly toward the church. Alternatively, it can be used for someone that is of Mormon descent but unbaptized or non-religious. Some Jack Mormons still support the goals and beliefs of the LDS Church, but for various reasons choose not to attend services or participate in church activities. They are also colloquially known as Cultural Mormons, the LDS equivalent of a lapsed Catholic, a "Christmas and Easter Christian"/ "Sunday Christian"(or based on an adage "Once a Baptist, Always a Baptist") and a "Yom Kippur
