Of course JD's going to say that it's choice, what else would you expect? It's not just 'convenient', it's a part of the teachings of the religion.

I have met many types of Christians, some of which you would never think were religious unless someone told you. There is certainly no mould for it. If you don't think you've met any different ones then maybe you just don't know when they are around you because you're looking for what you expect.

I heard of an experiment where some geneticists managed to genetically engineer gay fruit flies. Now that's an interesting outcome, but it's not enough to convince me absolutely that it's purely genetic.

To what extent do you believe behaviour is down to genetics?
