Bruh, there are polygamous societies on earth...RIGHT NOW proving this.
What are you talking about?
We have plenty of academic and sociological evidence for this.
Yes and they have been polygamous, it's not a new. It's ingrained in their culture and women do not have the same rights as American women. Establishing such a dynamic in a country where woman have rights is a totally different than just continuing on with established traditions in a male dominated culture.
