I don't believe, nor anyone else I hope, that the prevalence of jokes are a statistical tell about the true societal gauge of what is moral and immoral. Jokes are made about pedophilia (http://www.youtube.com/watch?v=4KyMhpzNNlM), jokes are made about bacon (http://www.youtube.com/watch?v=CaK9bjLy3v4), let me know if I'm wrong, but those seem separate from each other on the spectrum of "no-no's." Citing how comedians feel about something is not great in the way of proving a point about how the majority see that thing.
