A Newsweek article details the movement of polygamists to jump on the destruction of marriage bandwagon. Makes perfect sense, as the article says :
"If Heather can have two mommies, she should also be able to have two mommies and a daddy."
Or my family/marriage can be six daddies and three mommies, or three daddies and a bird or one cat, one aunt, six mommies and a nice man who lives with us. Monty Python stuff, huh?
Point being that once marriage loses its shape, it is meaningless.
Of course, polygamy will never catch on with the Brokeback Mountain crowd because it is too patriarchal and old fashioned. Mormons are alot of things but they are not hedonistic, New Age Gnostics, which is the flavor of the decade.
