Polygamy is great - as long as we make it fair so that I am allowed to have more than one husband too (that would fix the problem Floating in the Milk mentioned above). Wow, I can see it now - all my honey-do's would get done, the lawn would always be mowed, and the painting would get finished. All for the price of putting out a little more :o)
No wonder BY was endorsed polygamy!
If everyone would just see the reality that polygamy is God's law, they wouldn't be forced to marry their cousins - there'd be a whole world full of women to choose from. Not sure what we'd do with all those excess men, but I'm sure God could come up with something.
