I totally agree with ihno that it's important to step out of the anthropocentric circle, and a good way to do this is to read two great scholarly and scientific books:
- Bruce Bagemihl: Biological exuberance. Animal homosexuality and natural diversity.
- Joan Roughgarden: Evolution's rainbow. Diversity, gender, and sexuality in nature and people.
Theseeker started this thread with the question : Why does homosexuality exist among humans?
Reading Bagemihl and Roughgarden, my anti-question is this: Considering the fact that so many individuals in so many species of many different kind engages in same-sex sexuality, why shouldn't humans engage in same-sex sexuality?
And in particular, considering the fact that same-sex sexuality is very common among primates in general and the great apes in particular, it would be seriously strange if humans didn't engage in same-sex sexuality.
Humans do what bonobos, baboons and Japanese Macaques do. (Not to talk about sexy horndogs like Bighorn Sheep and Bottlenose dolphins
)
And in many ways we do it for the same reasons that the primates do it:
As so many other species, human beings live in social groups of varying sizes. I think it's a bad habit to intellectually "jump" from the individual level to the level of the species. Humans don't
live in the species, and neither do dog, wolfs, bonobos, seagulls, and bighorn sheep - "species" is a theoretical construct. But we
live in social groups, so does humans and everybody else I've been talking about.
As creatures living in social groups, non-procreative sex can be put to so very many intelligent uses.
First of all, non-procreative sex is great fun and pleasurable. It helps us to not die of boordom.
Second, sex is a great tool for making friends and sharing - as all GH members should know
Third, sex helps form social coalitions, i.e. sex is important for political reasons, didn't we know that....
So in my opinion, homosexuality doesn't exist as a biological problem.
