Homosexuality occurs naturally in people and has no ill effects on the individual. Since it only occurs in less than 10% of the population it really has no impact on the sustainability of the species.<quoted text>

We naturally mate to preserve the species. We pack for protection and communal support. These are to promote the species. As technology has advanced, these things change but still exist. We're naturally wired to reproduce and support the species.
We can have illness or disease that changes these drives. We can choose to ignore them. There is no third option. Homosexuality is either a disease or a choice in all cases.
Evolution has not selected against it and there is no evidence that it ever would. So in a sense it is a human trait no different from having red hair.
About 4% of people in Europe have red hair. That's even more rare than being gay.
So is red hair a disease or a choice?
