ttdtt - Are you serious?
The OT and the NT judge homosexuality. Paul says homosexuals won't inherit the kingdom. Are you seriously suggesting the WT could get away with permitting gay sex?
10% of all mammals exhibit homosexual or bisexual activity
Only humans and domestic sheep display lifelong homosexual preference even when hetrosexual sex is available.
--------------------------------------------
There are two propositions to be challenged in this part of the conversation.
First ttdtt's assertion, that: "10% of all mammals exhibit homosexual or bisexual activity"
A very high number of animal species (including, but not limited to mammals) can exhibit sexual behaviour with the same sex. Bruce Bagemihl's acclaimed analysis of zoological research on animal sexual behaviour discusses evidence of same sex, sexual behaviour in 450 different species of animals.
Because Bagemihl's work was essentially a meta study, analysing the work of many other zoologists, I do not think his conclusions have been seriously challenged.
It leaves a big hole in the Christian (including our former loving brothers and sisters) claim that the creation work of the YHWH/JESUS design team is always consistent with their moral laws.
The other assertion I wish to challenge is your (Cofty's) assertion that:
"Only humans and domestic sheep display lifelong homosexual preference even when heterosexual sex is available."
For example (just to cite two other species), Bagemihl, cites field work reports that some species of penguin's have been observed where some male bird's develop 'homosexual pair bonds' that last for the life span of the birds.
A sort of pair bonding also seems to develop with male elephants, and there are others.
However, the real problem with the remark is that it ignores the research that indicates that the 'natural' sexuality of most animal species is a sexual fluidity. This concept more easily explains the reality that can be observed in the natural world (human's included).
If non-one does any other research on the topic, have a look at the reviews of Bagemihl's book on Amazon

and maybe this page in Noel Castree's, "Making Sense of Nature." (p.85 of the google books site).
