This week, the U.S. Supreme Court rejected gay marriage appeals from Indiana, Oklahoma, Utah, Virginia, and Wisconsin, thus allowing lower courts to legalize same-sex couples. The policy debate is essentially over, and that's great, writes David Harsanyi—just don't say we now have "marriage equality." Consenting, polygamous adults still can't call their unions marriages.
The polygamy argument offends many advocates of same-sex marriage, who view it as an unfair and unnecessary distraction, notes Harsanyi. But on what logical grounds can a person argue that gay marriage is OK but polygamy is not? If your answer is an arbitrary declaration—such as, "The ideal union is between only two individuals"—then all you've done is redefine the parameters of marriage, Harsanyi argues. You support gay marriage, not "marriage equality."
