Ryan T. Anderson exposes the real agenda behind same-sex marriage advocacy in the New York Daily News.

Excerpt:

Same-sex marriage will never be widely accepted in America for a simple reason: It’s based on a lie. But don’t take my word on this; leading LGBT scholars and activists say as much.

Take Masha Gessen, acclaimed author and former Russian director of Radio Liberty. “Fighting for gay marriage generally involves lying about what we are going to do with marriage when we get there — because we lie that the institution of marriage is not going to change,” Gessen said last year.

Last month, I was part of a debate at the NYU School of Law at which Judith Stacey, a sociology professor at the university, declared: “Children certainly do not need both a mother and a father.”

Stacey went on to suggest that three parents might be better than two. In fact, while asserting she is in favor of same-sex marriage because of “equal justice,” Stacey admitted she isn’t a fan of marriage. “Why should there be marriage at all?” she asked.

I pointed out that marriage exists, and the government takes an interest in marriage because the sexual union of a man and woman produces children — and children need both a mom and a dad.

[…]In congressional testimony against the Defense of Marriage Act, she expressed hope that redefining marriage would give marriage “varied, creative and adaptive contours,” including “small group marriages.”

Stacey was among more than 300 scholars and advocates who signed a statement, “Beyond Marriage,” calling for legal recognition of sexual relationships involving more than two partners. During our NYU debate, she asserted that nothing gives the state an interest in monogamy.

The very day of the debate, Slate posted an article headlined “Legalize Polygamy!” The author, Jillian Keenan, argues: “Just like heterosexual marriage is no better or worse than homosexual marriage, marriage between two consenting adults is not inherently more or less ‘correct’ than marriage among three (or four, or six) consenting adults.”

She concludes: “Legalized polygamy in the United States is the constitutional, feminist and sex-positive choice.”

And this is why the marriage redefiners are doomed to fail: Redefinition has no logical stopping point. Its logic leads to the effective elimination of marriage as a legal institution. This will harm women, children and society as a whole.

If we redefine marriage to exclude the norm of men and women complementing each other in (ideally) a lifelong familial bond, Gessen admits, “The institution of marriage is going to change, and it should change . . . I don’t think it should exist.”

Is the the viewpoint of all gay people? Not at all. Many gay people are conservative and don’t want to change the institution of marriage. But it is the view that animates the activists who are pushing to redefine marriage for everyone. And if the activists succeed, it will affect everyone. It will affect children who don’t even have a say in the debate today, just like no-fault divorce affected children when that became the law of the land.
