The mess that lies beneath

Disgust represents a fear of contamination. And a great many traditional social boundaries and taboos exist as a way of protecting against contamination. The anthropologist Mary Douglas famously argued that the desire for purity and cleanliness is all about organising offensive things into acceptable social spaces – a place for everything and everything in its place. But the problem with a moral instinct that's all about policing the social boundaries created by disgust is that the sources of disgust are often the very same things that make us human. Cardinal O'Brien, for instance, is filled with disgust at the thought of gay sex. Which is why he is so intent on maintaining the boundaries of traditional marriage. But what a great many of us see in the Catholic church's response to homosexuality is simply a refusal of love itself – more specifically, love in all its sticky, squelchy reality.
