If we are all modeled in gods image than how can he condemn homosexuals?

Before I get started I would like to point out that its been proven that homosexuality is not a choice and is 100% genetic, but if you're like the christian church and view this in the way it viewed the concept of gravity up until 1980, please stop reading now, I don't have any desire to find out what you have to say. But if not here's my point. If in fact the bible is correct in saying that we are all modeled in the image of god and combining that with the scientific proof that homosexuality cannot be controlled then how can god condemn models of himself that have done nothing but live the way he created them? and with both of these facts indisputable the bible must be wrong in either saying that homosexuality is an abominable act punishable by death or that we are modeled after god. This point in itself could discredit Christianity and certainly should discredit the bible. Thoughts? I realize some of you answering will be religious or followers of Christian faith but just for this one question use logic and your own words to answer and please attempt to keep the emotions minimal, not non existent as I surely haven't but just keep it at a level where logic and rationale outweigh emotion.
