The scientific explanation to homosexuality is that it is an inherent characteristic you are born with in your DNA--that's why say it can't be changed. For something inherent in your DNA to be "cured", you would have to change the DNA. That is, mutating one's genes; aka Genetic Re-engineering (not to mention another Conservative Christian hot-topic).
Science can only prove that a typical homosexual's brain scans are indeed different from a typical heterosexual. But what they can't prove or determin is if those differences are indeed inborn, or if the differences manifest themselves AFTER an extended period of homosexual behaviour. (It's the chicken-egg debate.)
So let's go with the theory that it's a proven fact that homosexuality is indeed written in one's genes from birth. Does that really make a difference, or be used as an excuse?
Of course not. Take violent behavior for example. It's also proven that a violent temperament is partly written in the genes. But most people agree that violent, especially criminal violence can not be tolerated. So even if a person has violent tendencies, anger management therapies do not go after "curing" the violence by getting rid of it, because it's in their nature and it's bound to happen. What they are taught is to how to handle those violent tendencies when they occur.
Same with homosexuality. We are all tempted to do all sorts of things, be they from inherent genetic leanings or exterior influences. We are not judged by what temptations come our way, but how we deal with them. Perhaps those with genes that would have a much harder time fighting those temptations, but that's the challenge.
Whether homosexuality is biological or not is not the issue. It can't be used as an excuse as if to say that the person may not have strong control over it, so why force them to control such urges. But those making that arguement would be hypocrites if they don't apply that same philosophy to excuse child molestors, who also claim that it's in their nature. No one seems to have a problem wanting to stop them, even if that is in their nature too. Why is that?
