Serial polygamy, legalized by current divorce laws, has wrought enormous destruction upon our culture. Legalizing polygamy itself would only compound that.
In my opinion legalized polygamy is another step on the slippery slope into moral nihilism, something the left is feverishly working towards - a point I was trying to make in the post you replied to.
Very good point.
Also most folks don't know that divorce in 19th century Utah was quite high for that century. One historian took a look at a case study of hundreds of polygamous men and found that almost 1 in 5 were divorced. Brigham Young himself of 56 wives were divorced by 9 of them. (That's a 9-time divorcee!)
