"Homosexuality is like autism and schizophrenia: A few autism/schizo/homo genes have benefits, but too many is bad. If you have two nerdy or creative parents they may give birth to an autistic or schizophrenic child, because the child got too many autism or schizophrenia genes. There's no way for evolution to handle this, and it may be the same for homosexuality."

"Gay men do seem to have certain adaptive traits, because mixing feminine traits with masculine traits can be quite seductive for women, so a little bit of gayness is alright, too much is maladaptive because you won't reproduce."
