"The great enemy of the traditional family in the United States today is not the desire of gay couples to get married; it is the failure of heterosexual couples to get married and stay married. Over the past 10 years or so, while the country was busy debating same-sex marriage, the number of cohabiting couples doubled. Because of cohabitation, divorce and single parenthood, a third of children today do not live with two married parents — an ominous trend that began decades before same-sex marriage came along. The top priority for family policy today should be to reinforce the norm of marriage, which is exactly what gays want to do. By underscoring that marriage is something to which all Americans can and should aspire, same-sex unions are part of the solution, not part of the problem."
