Several years ago, I was invited to speak to a group of students at a Catholic university. The invitation came with a request and a caveat. I was to speak on chastity, but ideally, I was to avoid using the word. The Dean of Theology, who had invited me, had appraised the situation this way: perhaps more than anything else, the students need a challenge to chastity, but they are so turned off by the word that if we mention it in the title, very few will show up.
