True premise, false conclusion. Where the proponents of this view go wrong is in saying that marriage can do only one thing. Marriage multitasks. Yes, it binds biological parents to their children — something same-sex marriage will not change. But marriage also unites nonbiological parents to children: adoptive parents, for example, and step-parents and, yes, gay parents. And it does much, much more. It acts as a portal to adulthood and domesticity for the young; provides support and care-giving to adults; offers a safe harbor for sex and encourages monogamy; bolsters financial and emotional security; creates family networks (those sometimes-pesky in-laws); connects couples and kids to their communities.
I think the best definition of marriage is the one that most married people sign up for in their vows: “To have and to hold, from this day forward, for better, for worse, for richer, for poorer, in sickness or in health, until death do us part.” Extending the boundaries to include gay couples does not weaken that definition — it reinforces it. And to throw away the many social benefits that gay marriage provides because there is a single function that it can’t perform is perverse.
2. Same-sex marriage hurts children.
Opponents are right when they say that, other things being equal, children do best when raised by their married biological parents. But, again: true premise, false conclusion.
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.
And don’t forget that many gay couples are raising kids. Why would anyone think those children are better off if their parents can’t get married?
3. A collision with religious liberty is unavoidable.
Same-sex marriage, like gay rights protections generally, brushes up against objections from people who oppose homosexuality on religious grounds. What if a Salvation Army bookkeeper seeks health benefits for her wife? What if a student at a Baptist college demands married-student housing for his husband? Must religious-affiliated institutions choose between their principles and their nonprofit tax status? It’s a real problem. The myth is that it’s an unmanageable one.
