The important thing about your point is that society can be changed. It isn't a fact of nature.
Many would say that homosexuality IS a fact of nature. Therefore it's human society that is "unnatural".
National Geographic website writes:
Birds do it, bees do it, even educated fleas do it. So go the lyrics penned by U.S. songwriter Cole Porter.
Porter, who first hit it big in the 1920s, wouldn't risk parading his homosexuality in public. In his day "the birds and the bees" generally meant only one thingsex between a male and female.
But, actually, some same-sex birds do do it. So do beetles, sheep, fruit bats, dolphins, and orangutans. Zoologists are discovering that homosexual and bisexual activity is not unknown within the animal kingdom.
Roy and Silo, two male chinstrap penguins at New York's Central Park Zoo have been inseparable for six years now. They display classic pair-bonding behaviorentwining of necks, mutual preening, flipper flapping, and the rest. They also have sex, while ignoring potential female mates.
Wild birds exhibit similar behavior. There are male ostriches that only court their own gender, and pairs of male flamingos that mate, build nests, and even raise foster chicks.
Filmmakers recently went in search of homosexual wild animals as part of a National Geographic Ultimate Explorer documentary about the female's role in the mating game. (The film, Girl Power, will be screened in the U.S this Saturday at 8 p.m. ET, 5 p.m PT on MSNBC TV.)
The team caught female Japanese macaques engaged in intimate acts which, if observed in humans, would be in the X-rated category.
"The homosexual behavior that goes on is completely baffling and intriguing," says National Geographic Ultimate Explorer correspondent, Mireya Mayor. "You would have thought females that want to be mated, especially over their fertile period, would be seeking out males."
Well, perhaps, in a roundabout way, they are seeking males, suggests primatologist Amy Parish.
She argues that female macaques may enhance their social position through homosexual intimacy which in turn influences breeding success. Parish says, "Taking something that's nonreproductive, like mounting another femaleif it leads to control of a resource or acquisition of a resource or a good alliance partner, that could directly impact your reproductive success."
Sexual Gratification
On the other hand, they could just be enjoying themselves, suggests Paul Vasey, animal behavior professor at the University of Lethbridge, Alberta, Canada. "They're engaging in the behavior because it's gratifying sexually or it's sexually pleasurable," he says. "They just like it. It doesn't have any sort of adaptive payoff."
Matthew Grober, biology professor at Georgia State University, agrees, saying, "If [sex] wasn't fun, we wouldn't have any kids around. So I think that maybe Japanese macaques have taken the fun aspect of sex and really run with it."
The bonobo, an African ape closely related to humans, has an even bigger sexual appetite. Studies suggest 75 percent of bonobo sex is nonreproductive and that nearly all bonobos are bisexual. Frans de Waal, author of Bonobo: The Forgotten Ape, calls the species a "make love, not war" primate. He believes bonobos use sex to resolve conflicts between individuals.
Other animals appear to go through a homosexual phase before they become fully mature. For instance, male dolphin calves often form temporary sexual partnerships, which scientists believe help to establish lifelong bonds. Such sexual behavior has been documented only relatively recently. Zoologists have been accused of skirting round the subject for fear of stepping into a political minefield.
"There was a lot of hiding of what was going on, I think, because people were maybe afraid that they would get into trouble by talking about it," notes de Waal. Whether it's a good idea or not, it's hard not make comparisons between humans and other animals, especially primates. The fact that homosexuality does, after all, exist in the natural world is bound to be used against people who insist such behavior is unnatural.
it gives a rather beautiful view of bonobo homosexuality - we (humans) should be more like them. Yes, i am proposing widespread bisexuality as a way of making people more chilled out. I can't wait to have kids of my own, I'm going to bring 'em up proper!
