Society may no longer define marriage in the only way marriage has ever been defined in the annals of recorded history. Many societies allowed polygamy, many allowed child marriages, some allowed marriage within families; but none, in thousands of years, defined marriage as the union of people of the same sex.

I have a theory: I believe that with the advent of the United States and the lawful definition of marriage, it was defined as between one man and one woman. It was anti-polygamy, in effect saying no man can hoard his women.

The principle of plural marriage was revealed to the Mormons amid much secrecy. Dark clouds hovered over the church in the early 1840s, after rumors spread that its founder, Joseph Smith, had taken up the practice of polygamy. While denying the charge in public, by 1843 Smith had shared a revelation with his closest disciples.

No Congress ever has seen fit to amend the Constitution to address any issue related to marriage. No Constitutional Amendment was needed to ban polygamy or bigamy, nor was a Constitutional Amendment needed to set a uniform age of majority to ban child marriages.

The state's interest in marriage is stability. Generally speaking polygamy does not work for stability. Inherent in the whole polygamous movement is a deep and abiding misogyny and denigration of women. So polygamy is objectionable on lots of grounds.

Polygamy: An endeavour to get more out of life than there is in it.
