Polygamy is usually the horror story rhetorical end

16. Basically marriage is about contracts and legal rights. Its hard enough with serial monogamy

to sort out who gets what legally when its just between two parties at a time.

When you factor in multiple partners it would entangle the courts for many, many more years to sort through the contracts and legal obligations especially when it comes to children. If all of the adults are the legal parents of the children for example, how do you "split" the child custody equally between a man and 4 wives?

Polygamy made sense when the wife/wives and children were the man's property. Now we'd have messy child custody battles when infertile wife #1 wants custody sharing with wives #2, 3 and 4's children along with the husband.

If polygamy advocates could work out a way that was fair to everyone then fine but since virtually all polygamy is really about enforcing patriarchy, there's no way women would fair equally under the law in this system.
