The Immoral Joke Teller

The way that I understand an immoral Joe is not in terms of whether the utterance of the Joe comes into conflict with objective moral facts. But rather, it's about whether the utterances of the Joe come into conflict with conventional norms of morality and propriety. So it could be the case that an immoral joke teller who is regarded by many in their society as immoral based on the jokes that they tell might actually be up to something really morally important through their joke telling.
