> You realize those empires that practiced polygamy were brutally oppressive, yes?
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.
