"The principle drawback to polygamy maybe multiple Mothers in Law!!!!"
The very thought caused me physical pain!

Let's just change all the laws that inhibits/prohibits any one person from doing whatever that one person wants to do. Furthermore, if two or more people find compatibility in what ever it is they do....AMEN!
The other side is: There's more of me than there is of you, and me says you can't do that!

That doesn't count for much in this country these days! "Individual Rights" doesn't mean you can screw everyone else!

100,000 dead Canadians lay dead on foreign soil and I'd bet not many would be too happy about the "individuals" that find our traditions and customs to be offensive.
