Sexual acts that do not result in childbirth are not inherently unnatural unless you dynamically reassign the definition of "unnatural" with regard to sexual acts to mean "sexual acts that do not result in reproduction".
Which is of course, ridiculous given the rate at which humans reproduce in purely heterosexual situations.
Ok, I (as distinguished from the rest whose arguing this) am willing to accept your terms. But, I feel that we should take a hint from the late Cardinal Bernadin who I had the personal honor of talking to and adopt a policy that would do him justice and would be seemless in composition - as opposed to this horse-shit you're stipulating.
Thus, I'll agree that Homosexuality is *natural* (eg. found in nature regardless of the probobility and/or frequency) aslong as you then claim that Beastiality is natural as it's occurance is at a much higher occurance and for much the same reasons as Homosexuality.
As should Pedophilia be considered *Natural* as interblood-line intercourse is found throught the animal kingdom, although only most notworthly in humans. Hey, that's the only way in which most lower life forms reporduce is with their offspring and related organisms!
Furthermore, since you have so clearly opened my eyes to the many forms of *Natural* sex (appearently nature has a reason for them all) I feel that dispite the many walls you've knocked down between the many fringe forms of sex such as (but not limited to) homosexuality, beastiality, and pedophilia, they still can't knock down the one wall you admit to.
That the purpose and rationality behind the sexual relationships under heterosexuality serve a fundimental biological purpose that pushes forward the progress of the organisms gene-line.
Because, in retrospect the only tangible line that can be drawn between these forms of sexual relations are the biologically necessary reproductive aspects. And of these... only heterosexual relations would serve a purpose beyond the gratification and/or sexual desires of said parties.
So, thanks for opening my eyes to the many forms of *Natural* sex that sit parallel to homosexuality during the annals of Biological life on earth.
