Because calling it "sexual orientation" is just sugar-coating a desire to commit buggery. Nothing you or anyone else can do will change the fact that anal copulation (or any other same-sex genital stimulation) is a violation of Nature and God. Sodomy deserves contempt, the attempt by sodomite activists to 'normalize' sodomy and sodomite relationships deserves vigorous opposition. You, madam, are walking perilously close to advocating for sodomy and for sodomites.
According to my Bible, gossiping is a far worse sin than sodomy. I’ll go with that. You guys rate sins on their yuck factor.
