Thank you Neil for asking this question ! Unlike some people who pounced on me because I expressed my opinion freely although many people totally disagree with gay marriage & supposedly their opinions must be respected too ! Anyhow , homosexuaity is aberration , and homosexual behavior isn't natural for those so oriented . The orientation is a disroder and the behavior is pathological . Sexual preferance is cultural & environmental rather than genetic . There is a broad agreement that genes don't make it & genetic influence at most is minor . Individualistic reactions to random factors are very important . For example , divorce doubles the risk of later homosexuality in children . So social & family paths lead to it & the environment is much more powerful than genes in the development of homosexuality . Here , homosexuals are the victims of environmental problems and they are like patients who should get proper treatment .
