When Kirk Cameron — ’80s heartthrob-turned-staunch advocate for Christian conservative values — appeared on CNN’s Piers Morgan Tonight on Friday, he did not keep a lid on his controversial views about gay marriage.

“I think that it’s unnatural,” Cameron, who played Mike Seaver on the family sitcom Growing Pains,
said of homosexuality. “I think that it’s detrimental and ultimately
destructive to so many of the foundations of civilization.”

Piers Morgan told TMZ that he feels Cameron “was honest to what he believed” even if most people find his views to be “antiquated.”  Morgan says Cameron was “brave” for taking the bait. He says most folks would not voice their homophobia.

“In his interview, Kirk Cameron sounds even more dated than his 1980’s TV character,” gay-rights group Gay and Lesbian Alliance Against Defamation (GLAAD) fired back.

“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,” the organization said in
a statement.

Alan Thicke, who played Cameron’s father on Growing
Pains, tweeted, “I’ll address Kirk’s comments as soon as I recover from Rush Limbaugh’s.” 

Although former actor whack job Stephen Baldwin thinks Kirk Cameron did a “great
job” making antigay remarks on television last Friday, other celebrities
including Roseanne Barr, Debra Messing, and Cameron’s former Growing Pains costars Tracey Gold and Alan Thicke disagree.

An online petition has been launched against Cameron by GLAAD. Over 2000 people have signed it, telling the actor “it’s time to finally grow up.”
