Michael Reagan has defended controversial statements he made against the legalization of gay marriage.

In an appearance on CNN's Piers Morgan Tonight, Reagan, the adopted son of former President Ronald Reagan, told host Piers Morgan that he stood by his op-ed which appeared in the Ironton Tribune.

“Ultimately about changing the culture of the entire country; it inevitably will lead to teaching our public school kids that gay marriage is a perfectly fine alternative and no different than traditional marriage,” Reagan wrote. “There is also a very slippery slope leading to other alternative relationships and the unconstitutionality of any law based on morality. Think about polygamy, bestiality, and perhaps even murder.”

“I think it does send a slippery slope,” Reagan said on the program. “I think if you accept the redefinition of marriage then you're going to have to accept the redefinition all the way down the line.” (The video is embedded on this page. Visit our video library for more videos.)
