As larc's thread has mutated into the tired old nurture vs nature debate I thought I'd give a response to his question, which was
how do you reconcile the bibles attittude to homosexuality and the living breathing reality of human beings
I was at a recent screening of Trembling Before G-d, a documentary on homosexuals in the Orthodox community who want to be practising homosexuals and still be accepted as part of the Orthodox faith. (My opinion is that they're wanting to have their cake and eat it but I was interested in the reasoning). The film was followed by a Q&A with the director, a local rabbi and the only gay rabbi there is. The prohibition all stems round Leviticus 18:22 but the reading of it in Hebrew, by both rabbis, was of a prohibition of penetrative anal sex. The gay rabbi is about to publish a book on what he reckons is the "true" meaning of this, which he sums up as a prohibition for using any sexual act as a form of domination. The local rabbi didn't agree with that but pointed out that the same phrase that we translate as 'detestable to God' is also applied to the mixing of wool & linen, which most Orthodox Jews choose to ignore. The rabbis interviewed in the film all came across surprisingly well and not the rabid fanatics I expected, but that may reflect my profound ignorance of the Orthodox community or just possibly the p.c. face they can show that the WTBTS can also have.
So if it's just anal sex that's off the menu there are obviously a number of alternatives. Intriguingly the rabbis struggled to provide a biblical reason against Lesbianism, so ladies, go for it!
Another interesting point that the director made was that we have to allow for a certain degree of homophobia. His reasoning was along the lines that 'Rome wasn't built in a day' and pointed to the fact that while his own mother is now a campaigner for gay rights, it wasn't a road to Damascus conversion for her but a gradual change. The film has been screening for 2 years around the globe and is breaking ground with educationalists in Israel and yeshivas around the world.
For the record I'm not Jewish, nor a Christian, but homosexual.
