The case with the Mormon offshoot is wrong because  much of it has to do with under aged girls, or girls who have been coerced into these relationships. But not all issues of polygamy or polyamory are like Bountiful. Many of them involve consensual adults mature adults who know what they are doing and are able to make sound decisions.  Honestly, if the government of Canada thinks that it's lawful and okay for people of the same gender to marry. There should be no limit on the amounts of spouses people should be able to legally marry if they choose to do so.  Then Canada can be really the land of the free that big and small liberals espouse.
