"finally, think of the ramifications of actually finding a "gay gene"--in utero testing for gayness would begin, and I actually think there are folks out there that will abort at the first sign of a gay fetus."

there are actually recent scientific/medical discoveries latley (due to new bain imaging techniques) that clearly show physical differences in brains of people with different sexual orientations. Whether this is a normal variation in the human species generally or whether it is an abnormality is something "they" are going to argue about for a long time.

Personally it's as pointless as arguing if the sky is blue do we ban it?
