To this MIT-trained biologist, it's an assertion that has not been scientifically proven. In the absence of such proof, thousands of years of tradition in multiple cultures (condemnation of homosexuality is hardly limited to the Judaeo-Christian tradition) should not be lightly discarded.
Science has the evidence - given from reformed "Gays".
As evidenced by the natural biological functions of the male/female and as testified to by every other specie on the planet, I'd be least likely to assume homosexuality is anything but a choice to pervert the natural use of one's body.
IOW, science has not proven - nor has one thread of evidence that the initial perversion is anything less than a choice - but much to the contrary. After engaging in the acts frequently, the individual becomes the slave of HABIT.
Not only have thousands left the homosexual lifestyle, there is no biological or genetic evidence to support homosexuality. The facts support, overwhelmingly, the major factor in determining homosexuality is environment.

Again, environment is the key factor in determining homosexuality. Here's some links on genetics and environment
