What a strange post. You realize those empires that practiced polygamy were brutally oppressive, yes? Women didn't so much have a choice as in forced into polygamy because they were treated as property and that's about as far away from the hippy movement as you can get when it comes to individual freedoms.

OP was talking about stability, not oppression. The Amish are oppressive, though not seemingly in a brutal way. Many societies with similar values to the Amish were also extremely oppressive.
Regardless, I gave examples of incredibly brutal societies that valued monogamous marriage and sex for procreation. My whole point is that these variables have nothing to do with whether a society is stable, but it's also true that they have nothing to do with whether a society is nice to live in.
Afaik, being married as an Amish can be quite oppressively too. No way out if your husband beats you. No divorce means exactly that - no matter how bad it gets, victim gets blamed.
