Its all a form of mental aberration and mental illness.
None of it results in healthy, happy, productive, well-adjusted new Citizens.
I believe that Gay behavior, as well as Pedophilia, and number of other sexual aberrations, are all the result of on inbuilt, genetic, psychological pressure relief valve, which causes a down trend in birth rates, when a society is undergoing over-population pressures.
It is not wrong, or evil, or UN-natural, it is perfectly natural, and a inherent part of the human genome and instinctive psychology, to branch into various non-procreative sexual aberrations, when facing the societal pressures of over-population.
It has been a part of humanity for millennia, and won't stop anytime soon.
I don't condemn those afflicted with it, I just don't join in with their instinctive, pressures triggered, mania.
There but for the grace of God go I.
