DiA tries to wrap his head around the fact that more people find polygamy "acceptable" than extramarital affairs:
I would probably agree that cheating on your spouse is "morally wrong", but given that about half of married people do it I'm not about to shun anybody. … Still, even accounting for the simplistic framing, the extremely high "Morally wrong/acceptable" ratio there suggests to me that judgmental puritanism is in pretty good shape in America these days.
