"Dynamic Polygamy"

Sociologist Dalton Conley discusses modern culture:

...we are living with a lot of remarriages and blended families, which is a form of polygamy. You can have ongoing obligations to the children you had by your first partner living in the hut across town, through child support and alimony, and the same obligations to your current family. So in terms of kinship ties, and the economic relations inherent in those kinship ties, we're no different than a kind of "pre-modern" polygamous society.

But gay couples choosing fidelity is the big problem!
