I’m not NDMormon, and I’m not LDS, but:
I’m reminded of Mark Twain’s comments after having seen the Mormon women. He changed his mind pretty quickly about polygamy being all about sex. The Mormon women were pioneers and as such tended to be stocky, muscular women due to the hard labor their life entailed.
14 sounds dreadful today, but back then? Heck, I think 14 is still the age of consent in some states today. My Grandma married for the first time when she was 16!
The Mormons had a problem endemic to religious movements anywhere. More women than men. Given there was no welfare, food stamps or other types of assistance, and little female employment opportunities; marriage was the way women survived in those days. Especially in the frontier communities. Oftentimes the year of mourning for widows was suspended because of the need for the field work and building to be done and woman and children needing financial support. So polygamy solved the over-supply of female problem and undersupply of men.
Was it abused on occasion? Of course, show me a perfect community, and I’ll show you Heaven.
