As any sin passes through its stages from temptation, to toleration, to approval, its name is first euphemized, then avoided, then forgotten. A colleague tells me that some of his fellow legal scholars call child molestation "intergenerational intimacy": that's euphemism. A good-hearted editor tried to talk me out of using the term "sodomy": that's avoidance. My students don't know the word "fornication" at all: that's forgetfulness.
