1 Introduction
This essay defends the view that homosexuality is abnormal and hence undesirable - not because it is immoral or sinful, or because it weakens society or hampers evolutionary development, but for a purely mechanical reason. It is a misuse of bodily parts.

they are untrustworthy. Mr Jones pulls all his teeth and strings them around his neck because he thinks his teeth look nice as a necklace. He takes pureed liquids supplemented by intravenous solutions for nourishment. It is surely natural to say that Jones is misusing his teeth, that he is not using them for what they are for, that indeed the way he is using them is incompatible with what they are for. Pedants might argue that
Jones 's teeth are no longer part of him and hence that he is not misusing any bodily parts.
To them I offer Mr Smith, who likes to play
"Old MacDonald" on his teeth. So devoted is he to this amusement, in fact, that he never uses his teeth for chewing - like Jones, he takes nourishment intravenously. Now, not only do
