Fascinating discussion. Also, I think it has something to do with the lack of descriptors being in use for the overall majority. Now, I'm left-handed, and identify as such (writing, kitchen appliances etc), but 75-90% of all humans (heh) don't go around and identify as right-handers, do they? It is always the odd ones out who get labelled, isn't it? I could get on about the Other, but I can't be bothered at the moment. Plus, I haven't read enough on the subject.
