Homosexuality is identified as 'sin' in both the Old and the New Testaments, but it is no different than lying, coveting, etc. Calling something 'sin' implies a value judgment. We're all sinners and have fallen short of God. It's not like I'm a mediocre sinner, but homosexuals -- they're bad sinners. If we're all sinners, the value ascribed to Sinner A is no different than Sinner B. Calling something sin doesn't make you phobic/bigoted, but treating or valuing someone differently does. Homophobics use the Bible as a tool justifying bigoted behavior. Homphobics' opponents misinterpret it out of context. Christ-followers recognize the central message of the Bible is loving regardless of past, predisposition or lifestyle. As for 'natural', there's a genetic predisposition toward alcoholism. Does that make it OK because alcoholics were created that way? Everything in our genetic makeup -- talents, predispositions and even diseases -- is designed to use as a gift (talents) or a burden to work through (predispositions, etc.) in order to bring glory to God.
