To The Saint:
Gays and lesbians do not need the approval of the religious, they just need to be left alone.
According to Biological Exuberance written By biologist Bruce Bagemihl Phd:
"Many people continue to believe that homosexuality doesn't occur in nature, and use this belief to justify their opinions about human homosexuality.
In fact, not only has homosexual behavior of various types been scientifically documented in hundreds of animal species worldwide. Same-sex pair-bonding and co-parenting are found in Grizzly Bears and Barn Owls, and homosexual courtship and sexual activity in several species of Salmon.
I wrote Biological Exuberance to expose and challenge the limitations of the "nature vs. nurture" debate. Too many times, evidence of homosexuality in animals is used to support the idea that homosexuality is entirely biologically determined, genetically controlled, or otherwise fixed at (or before) birth -- and more broadly, to argue for its "naturalness" in people. In the process, the complexities and nuances of sexual orientation and gender -- in both animals and humans -- are overlooked.
This book shows how social, environmental, cultural, geographic, and individual factors also come into play in the expression of homosexuality in animals. In other words, both "nurture" and "nature" are relevant, even in a nonhuman context. If nothing more, then, I want readers to understand that it is overly simplistic to equate homosexuality in animals with its "naturalness" or automatic "acceptability" in people.
Finally, Biological Exuberance is about far more than animal (homo)sexuality -- it presents a new vision of the world and our position in it. Much of the discourse on animal homosexuality -- both scientific and popular -- has floundered in attempts to find an "explanation" for the phenomenon or fit it into traditional theories of evolution. I suggest in this book that such attempts, while useful up to a point, are ultimately misguided. What is needed is not yet another simplistic "answer", but an expanded concept of what is possible."
Maybe this will help broaden your view on sexuality in nature so you can get on with your religion and stop worrying about the 'morality' of others.
