Homosexuality is usually defendded in the context of an alternate biological sexuality or that it has a genetic component. This is an attractive argument for both its advocates and critics, the latter of whom rationalize that it must be genetic as no one would voluntarily engage in homosexual acts. Truth is no one knows.... just as no one can validate the notion of a “G-d” gene that makes for belief or disbelief as the case may be.
But the preponderance of evidence shows that it is a chosen lifestyle; just as there is a preponderance of evidence that alcoholism is a choice, though know one knows for sure on this either.
That does not, however, determine our behavior.
A person with a genetic sensitivity to alcohol can still choose not to drink alcohol or become an alcoholic. A person with an inborn irascible temperament can still learn anger management and control outbreaks of wrath. A man erotically attracted to children can refuse to act on that attraction.
It's the behavior, the conduct, that concerns us. Every person, without exception, has to tamp down some of their inborn drives in order to live justly and peaceably with other people.
If I gave in to my deep-seated inclinations and impulses, there would be a great many more incendiary events across the USA!
