Ex-Mormon (or Exmo) refers to a isaffiliate of The Church of Jesus Christ of Latter-day Saints or any of its schismatic breakoffs, collectively called "Mormonism." Ex-Mormons typically neither believe in nor affiliate with the LDS church. In contrast, Jack Mormons may believe but do not affiliate; and Cultural Mormons may affiliate but do not believe. The distinction is important to ex-Mormons, many of whom see their decision to leave as morally compelling and socially risky. Some ex-Mormons find that their Mormon family and friends tend to either shun or find fault with them after their exit. Aggregations of ex-Mormons may comprise a social movement.
