Morally Sickening

In response to Virginia Postrel on the abuse of the word brave, Glenn Reynolds writes:

What really interests me is that people think that they've made a moral argument against genetic engineering when they say that the idea "sickens" them. The idea of sodomy "sickens" some people, too. So does the idea of interracial marriage.

So you feel ill. Why should I care? After all, pompous, empty-headed moralizing sickens me, and nobody's stopping that.

As Glenn would say: Heh.
