Conversion therapy: God only knows

An estimated 700,000 adults in the U.S. have received a controversial treatment known as reparative, or conversion therapy, under the belief that homosexuality is caused by nurture, not nature, and can be "cured." Erin Moriarty talks with young men and women who had undergone the treatment (voluntarily or at the behest of their families) in order to adhere to their church's teachings; with Alan Chambers, who was the charismatic director of Exodus International, which promised to convert those with "same-sex attraction"; Nashville pastor Stan Mitchell, who has rejected conversion therapy; and Jeff Johnston of Focus on the Family, which continues to promote the practice for parishioners who do not want to be gay.
