Monogamy and cheating

Elizabeth's picture

I was reading Doonesbury yesterday and the cartoon pointed out the hypocrisy of certain Republican candidates for the presidential nomination. Between three of the leading Republican candidates, there are five divorces, "four really messy and all involving adultery."

Why do we retain monogamy as our dominant culture ideal when even those who most staunchly support it don't live by it? Why instead don't we teach a loving, honest and open polyamory as the ideal?
