Ah, sitcom stars of the '80s and '90s. They never fail to amuse in their later years, or in this case horrify.

Most have heard this past week of some highly controversial comments former 'Growing Pains' star and born-again Christian Kirk Cameron made to Piers Morgan during an appearance on CNN, describing homosexuality as "unnatural," and later adding, “I think that it’s detrimental, and ultimately destructive to so many of the foundations of civilization.”

Predictably and understandably so, GLAAD immediately reacted with their retort that "Kirk Cameron sounds even more dated than his 1980s TV character.” But what of the celebrity and LBGT community at large, even some of Cameron's former 'Growing Pains' stars' reactions? We took to the Twitter-verse to uncover some of the best, and sharpest retorts to Cameron's controversial words!

Tracey Gold, best known for playing Cameron's on-screen sister Carol was among the first to respond, while others were more non-chalant and sardonic in their responses, such as 'How I Met Your Mother' star, gay icon and former child-star himself Neil Patrick Harris.

Fellow LGBT icon and 'Modern Family' star Jessie Tyler Ferguson kept to the more sarcastic, while not to be out-done with the 'Growing Pains' parodies, 'The Good Wife' star Josh Charles joked about Cameron's on-screen parents.

On the other hand, lesser-known conservative Baldwin brother Stephen Baldwin supported Cameron's words, even praying for Piers Morgan.  What would Alec say?

But gun to our head, we'd have to go with personal favorites from former 'Growing Pains' star and Cameron's on-screen father himself, Alan Thicke, who tweeted forth three gems.
