Nurture can make a guy Metro-sexual...but not gay.
I do believe it is an anti-productive Mutation which is different than something being what we think of as genetic. Something "genetic" is generally handed down, while homosexuality is something that happens in a one-off fashion. It has been suggested that it is occurring more often in populations with third or fourth level inter-breeding such as Europeans but much more infrequently in larger populations like Africa or India. However, studies cannot be conclusive because it is difficult to determine when it is not happening or when it is not being reported due to cultural differences. Homosexuality happens more like a "genetic" defect for example being albino... But, if you say that you get labeled a homophobe.
look, Gays are clearly people too, who did not choose to feel the way they feel, and should be allowed and even encouraged to follow their dreams of a normal life, but there should be no doubt that it is counter-productive to the survival of our species.
It does suck that people are prejudged and treated as outcasts for something they cannot help, but on the same hand, scientists will never have answers because they have to pretend it is a good thing or risk being called a biggot.
