’80s sitcom star turned religious activist Kirk Cameron is not a fan of homosexuality and he isn’t shy about sharing his feelings on the subject.

During a new interview with Piers Morgan the Growing Pains heartthrob who transitioned from a “teen-idol-atheist in Hollywood and became a devoted follower of Jesus Christ in the middle of [his] career” explained that he believes homosexuality is “unnatural… I think that it’s detrimental, and ultimately destructive to so many of the foundations of civilization.”

On the issue of marriage equality Cameron remarked, “Marriage was defined by God a long time ago. 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. So do I support the idea of gay marriage? No, I don’t.”

Cameron was in the 2008 film Fireproof. The rest of his Growing Pains co-stars, thankfully, support LGBTQ rights and marriage equality.
