Well... it's a wacky lifestyle in my opinion lol. *Insert rant critical of religion here*. Aside from my opinions about that stuff, I don't think they should be prosecuted. The government should mind its own business and allow them to practice their religion. If the kids aren't being abused or mistreated, or if there isn't any kind of actual detrimental, criminal act being committed, then the gub'ment should mind its own damn business. 99% of those in government should be prosecuted for a long list of crimes, all of which are far worse than polygamy lol.
