the following is entirely my opinion.
I personally do not believe in divinely mandated or authorized polygamy or anything else that stands to decimate another persons peace, security, loyalty, and joy.
I believe polygamy, infidelity, and cheating are all 100 % human behaviors originally born from debasing womens value, and elevating the position of power for men.
anyone who breaks another’s trust in such a way will pay heavily at some point for such atrocities, I can only hope.
taking a little bit further, I believe that in the earliest of times, women’s ability to give birth was probably a mystery to men (not knowing how the baby got there to begin with) and that women were held in great esteem. Once men figured out how to make women property, which is of course what polygamy is, men finally leveled the playing ground but over did it. We’ve never found our way back.
I think it’s very convenient to put such a heinous practice on God rather than to take personal accountability for our own human tendencies. The bible is men’s stories written with influence of God but not hand written by God. It has justified to a lot of evil people a lot of evil behaviors.
