Before last Friday’s Supreme Court ruling, many of us argued that same-sex marriage could or would lead to polygamy. Gay marriage proponents were quick to dismiss our warning. But consider Chief Justice Roberts’ dissent to the court’s decision: “Although the majority randomly inserts the adjective ‘two’ in various places, it offers no reason at all why the two-person element of the core definition of marriage may be preserved while the man-woman element may not.

Indeed, from the standpoint of history and tradition, a leap from opposite-sex marriage to same-sex marriage is much greater than one from a two-person union to plural unions, which have deep roots in some cultures around the world. If the majority is willing to take the big leap, it is hard to see how it can say no to the shorter one. It is striking how much of the majority’s reasoning would apply with equal force to the claim of a fundamental right to plural marriage.” FULL REPORT
