Natoma is also very good at utilizing this almost semantic twist to dichotomize and arbitarily divide groups based on genetic problems, mutations, or his definition of natural (as opposed to what Joe said).
I just find the fact that he must do such manipulations to prove this elusive biological voice that's telling him his life decisions have some tangible basis, this almost reassuring aspect to being "biologically correct" (or whatever that is).
I still think this is so strait-forward. Take the thought experiment where you have two planets: planet (a) has just homosexual males, and planet (b) has proportionate amounts of heterosexual males and females. And then check to see which is still harboring life after a completed generation.
If we assume that a goal of life is to survive and that nature (as seen by the intelligent life we've found) seems to take the path of survival of it's genetic lineage and even further this cause via the infamous
Survival of Fittest doctrine where genetic information is further refined and passed on.
A very definition of biological is
"Related by blood or genetic lineage" www.dictionary.com
Thus, how can you have a practice that's diametrically opposed towards this overriding goal and classify it a manifestation of the natural world (just like *normal* sexual intercourse) when it can't exist in the natural world, nor can it be furthered or refined?
I mean, lets be honest Natoma - as far as nature and biological progression is concerned, you're a dead-end.
Now, this situation becomes muddied when you bring self-reflecting, conscious being into the picture like Natoma who, understantably, want some justification that his life choices are correct and needs this feeling of vindication and collective biological goals. Not to mention a tangible barrier between his practice and other classical *taboo* practice involving family, animals, priests...
But, I just don't see it Natoma. Hey, if you wait around a few hundred year, you can jump on the bandwagon and fight the emerging incestual practicioners with us.
