DAMNED TO HEAVEN - Warren Jeffs - POLYGAMY
Thanks for the link. That was spooky Warren Jeffs is evil. I was going to add that as in traditional marriage all partners must be of legal age, etc. but I didn’t want to get long winded.
Maybe polygamy can’t work outside of a tribal society. But before I declare it unconstitutional I would have to be convinced that polygamy necessarily entails mind control, pedophilia, and whacky religious cults.
