I don't think you need to use the bible to show that homosexuality is wrong. Here's another good point. Homosexuality has never worked in any civilization in history. Those civilizations that openly supported and condoned homosexual lifestyle failed. Not that homosexuality was the direct cause of their failure, but that the acceptance of homosexuality was an indicator that the moral center of that civilization was going or gone. Collapse soon followed. The laws of nature (let alone god) are absolute. Violate them at your peril. I'll say it again, structure, not pleasure, determines function. We don't inhale because it feels good, we inhale because we have to breathe to live.
