Do you think the majority of Mormons support polygamy? They have that up a long time ago. The ones who still engage in polygamy left in offshoot groups.
I had a guy that worked for me that thought polygamy was a great idea. Another of my crew said he wouldn’t work with the guy because he was effing nuts. First guy was nuts and morman, second guy morman and had been divorced twice. He couldn’t see why you’d want more of what he couldn’t seem to live with one of.
