Tokos wrote:That has no bearing on the matter. Homosexuality, evolutionarily speaking, is as bad for the individual organism as sterility. No one argues that someone being born sterile is somehow beneficial to their genes. If we were ants, with workers intended to be sterile, maybe, but we're not.
Just because something exists doesn't mean it has a grand purpose. See: haemophilia.
When it exists in hundreds if not thousands of species separated by hundreds of millions of years of evolution in roughly the same percentage, there's probably a reason for it. And when said species almost all share another trait in common, one that would provide an evolutionary explanation for the existence of something, then it's even more likely there's a reason for it.
