Cameron's career broke open playing Mike Seaver on the 1980s sitcom, "Growing Pains."
Cameron's appearance on CNN Friday created more heat than light when the boy-toy actor/atheist-turned-evangelist laid out his traditionalist views on marriage.
"Marriage is almost as old as dirt, and it was defined in the garden between Adam and Eve. One man, one woman for life till death do you part. So I would never attempt to try to redefine marriage. And I don't think anyone else should either," Cameron said. "So do I support the idea of gay marriage? No, I don't."
He also presented Piers Morgan his views on homosexuality.
"I think that it's unnatural. I think that it's detrimental and ultimately destructive to so many of the foundations of civilization," Cameron, 41, said.
The Gay & Lesbian Alliance Against Defamation issued a statement in response to the actor's recent appearance on the CNN program, The Hollywood Reporter said.
"In this interview, Kirk Cameron sounds even more dated than his 1980s TV character," said Herndon Graddick, senior director of programs at GLAAD, in a statement. "Cameron is out of step with a growing majority of Americans, particularly people of faith who believe that their gay and lesbian brothers and sisters should be loved and accepted based on their character and not condemned because of their sexual orientation."
"With an increasing number of states recognizing marriage equality, Americans are seeing that marriage is about committed couples who want to make a lifelong promise to take care of and be responsible for each other and that gay and lesbian couples need equal security and legal protection. That's not 'redefining' anything."
