Clay Aiken says marriage amendment goes 'way too far'

"Families looks different. They have always looked different. You have single-parent families, families with parents of different races, families with parents of different religions," he said in the video. "No matter what we want a family to look like, we can't put into a constitution – a document that is supposed to protect our rights – one narrow definition."

Aiken, who appeared on "American Idol" in 2003 and announced he was gay in 2008, was featured in the video for the group Protect All N.C. Families.

The amendment, which will appear on May's primary ballot, would define marriage as being between one man and one woman and outlaw civil unions. 

Aiken, who has a son with longtime friend Jaymes Foster, said it would ultimately hurt the children of non-traditional families.

"I think an amendment like this goes way too far," he said. "It will take away protections from kids who, right now, may have access to healthcare because one of their parents has healthcare at work."

"We just believe that the definition should be redefined in the state of North Carolina," he said.

North Carolina is the only state in the Southeast without a constitutional amendment limiting marriage to one man and one woman, but same-sex marriage is against the law already.

Wooden said that giving the Bible's definition of marriage constitutional protection is the "will of the people."

The only way protect marriage, Wooden said, is to get out and vote on May 8.

"I just hope that those of us who are in favor of the amendment don't assume that it's a done deal or a slam dunk and we stay home and wake up the next morning shocked," he said. "Get out and vote and allow your votes to be heard."
