As to the "incontrovertable [sic] truth," every Christian bible, as well as the Jewish Pentateuch and the Koran, condemn homosexuality in the same words. They should; they were written by the same author.

But hey, if Reverend Jim's First Church and Bait Shoppe approves, maybe biology, 2,000 years of western thought, and 10 billion people are wrong and you're right.
