Sexual orientation as a choice?

So I was just pondering the statement that “straight” people don’t choose to be straight. Of course, the über-religious will say that’s because it’s the natural order of things…the way we’re created. But if someone is physiochemically wired a certain way, doesn’t that imply that God either makes mistakes or that God is a watchmaker rather than a timepiece? To avoid that theological quagmire, they equate homosexuality with sin and since sin necessarily depends on choice, sexual orientation must therefore be a choice as well. It seems to me that the blindly religious are spending way more energy trying to avoid the theological heavy lifting than it would take to just sit patiently and meditatively for understanding to come. Theophilosophy shouldn’t weaken one’s faith; it should strengthen and deepen it. As an axiom, a sovereign deity cannot err and all people must have the same free will. So shouldn’t it be the case that if heteros don’t choose to be hetero, homos don’t choose to be homo?
