Homosexuality: Nurture or Nature?

Homosexuality is an issue in churches, state legislatures and even presidential elections--especially with anti-gay Christian conservatives in the Republican Party. Last year, Pastor Ted Haggard was fired from the 14,000-member New Life Church for admitting a three-year relationship with a male prostitute. Now, Haggard says, three weeks of intensive therapy have him on what he calls "the road to recovery."  One friend says Haggard is "completely heterosexual." Such claims raise a lot of questions.  We discuss a personal and scientific question with political implications.
