The push to legalize “gay marriage” is about far more than equality. It’s about dismantling the institution of marriage altogether.

Marriage only makes sense as a societal construct when it is defined as the union of one man and one woman. Marriage is valuable to society insofar as it creates familial stability and brings about the conception and education of new citizens. It behooves the state to incentivize the continuation of the population, and thus, the flourishing of the nation.

This is why those pushing to redefine marriage really just want put an end to it. As it stands, the institution of marriage excludes those relationships that do not provide a demonstrable benefit to society. Those in unconventional relationships seek not only inclusion, but legitimacy. They want the same rights, the same incentives, as are currently provided to those in traditional marriages. And they know the only way to make that happen is to take the existing system apart. Taken further, they want to ensure that anyone opposing the push to legitimize and sanction non-traditional sexual behavior under the misnomer of marriage is ostracized and treated as a bigot.

It is my belief that the fight to resist gay marriage in America has already been lost. I know there are many who disagree. But even now, as I write this, I just received a notification that a federal judge in Norfolk struck down the gay marriage ban here in Virginia today, saying that it violates the Constitution’s guarantee of equal protection.

The states are falling like dominoes. Even the ones that formerly held fast.

We know that the push for universal acceptance of gay marriage will lead to the inclusion of other relationships formerly considered deviant. We’ve even seen efforts to de-stigmatize criminal sexual behavior like pedophilia.

But the next fight is already here, and it’s about something else. It’s the push to legitimize and decriminalize polygamy. And it’s happening now. Why? Jillian Keenan made the case last April at Slate:

While the Supreme Court and the rest of us are all focused on the human right of marriage equality, let’s not forget that the fight doesn’t end with same-sex marriage. We need to legalize polygamy, too. Legalized polygamy in the United States is the constitutional, feminist, and sex-positive choice. More importantly, it would actually help protect, empower, and strengthen women, children, and families.
