What is the main conflict in Stranger at the Gate: To Be Gay and Christian in America by Mel White?

Stranger at the Gate: To Be Gay and Christian in America is the story of pastor and ghostwriter Mel White, who was once a major ghostwriter for leaders of the Religious Right, including Jerry Falwell, Pat Robertson, Billy Graham and Jim and Tammy Faye Bakker, but simultaneously struggled with his sexuality. Today White is an openly homosexual religious and political activist, but he grew up in a Christian evangelical household where homosexuality was never talked about and was considered a sin.
