You know, I could actually live with their polygamy issues if
a) they entered into it willingly
b) they were adults
c) they didn't attempt to claim absent fathers and welfare benefits for the children
d) both male and female members were free to leave the society if they wished. And free to come and go from the community when they wish.
e) all births and deaths were properly reported to the county, state, feds.
f.) all children received a formal education, at least through grade 12.
Yes, polygamy is illegal. But how many marriages don't have some adultery happen at some time. Right, no. But it is reality. But because they formally recognize it, it is illegal. If they as adults wish to give permission for their spouses to have relationships with others, why should I object?
As far as the communal living aspect, again that is their choice. But when they choose to turn their income over to the church, the church should be responsible for the education of the children beyond the 12 th grade if the child so wishes. All children (male and female) should have the opportunity for further education and/or vocational training.
As far as abuse and subjugation of the women, it is like a domestic violence relationship. If they (as adults) choose to stay in that type of relationship, then it is their right to choose. You can encourage them, you can support them, but you have to let them choose if/when it is right for them to get out. And I really believe that some women thrive in that type of relationship. They seem to feel the need to be controlled, to not have to take responsibility for decisions. Some women may be drawn to that type of relationship because of the fact that they really don't have much contact with men, and have a strong "sisterhood."
So while I personally wouldn't choose a polygamous relationship, some people might.
