Tony Perkins, president of the Christian conservative Family Research Council (FRC), has said gay marriage will “fundamentally alter society.”

Participating in a Face the Nation panel discussing the issue of marriage equality as it relates to two upcoming cases before the Supreme Court, Perkins argued that such unions threaten rights.

“If you want to talk about rights, let's talk about those rights that have been lost in the wake of same-sex marriage,” Perkins said. “And religious freedom has been among them. You've got Catholic Charities no longer doing adoptions. Not providing vital services right here in this city, as a result of same-sex marriage in DC. You have got parental rights that have been lost. Parents no longer being able to determine what their children are taught, whose moral values they're taught at school. We have small businessmen losing their rights because they won't participate in same-sex ceremonies.”

“This ultimately is not about marriage. It's not about the marriage altar, it's about fundamentally altering society. And so you can't divide the two.”

“This will be a major public policy shift that will move us further away from that ideal goal of giving kids a mom and a dad, because by law we would be denying kids a mom and a dad.”

Evan Wolfson, president of Freedom to Marry, rebutted some of Perkins' claims.

“What we're talking about here is who can get a civil marriage license from the government in order to strengthen their family under the law,” Wolfson said. “It's not about telling any religion what it must do.”

“Marriage is not defined by who is denied it. When gay people share in the freedom to marry, it doesn't change your marriage, it doesn't change Tony Perkins' marriage. My marriage is my marriage and it means that I'm able to share in the same aspirations of commitment and love and support and dedication and connectedness.”

“The gay people are not going to use up all the marriage licenses when we enter marriage.”
