Camille claims the explanation for homosexuality is not biology but adaptation. Good luck trying to prove that. Camille makes a lousy scientist. How is it that a set of circumstances that can steer a person toward homosexuality can also steer another toward heterosexuality, if not for genetic differences? This is not to say that one is born gay, but rather with a greater potential to become so. Excuse the tautology, but I believe the genetic imperative trumps nurture, or adaption if you prefer.
It's just like intelligence - you're either born with it or you're not. And this is very easy to prove. Genes are king - they
are the crytalization of millions of years of evolution, the concentration of earth's history into a chemical code. They explain us, almost completely, if we look into them hard enough.
Everything else is sophistry, psychobabble and, worse of all, the
pathology of religion.
