Appearing on Larry King Now, surgeon-author Dr. Ben Carson said that he believes in the Libertarian philosophy of live and let live and supporters of marriage equality do not.

Host Larry King asked Carson, a pediatric neurosurgeon at Johns Hopkins University and a conservative celebrity often mentioned as a possible GOP presidential candidate, “why isn't same-sex marriage a civil rights issue?”

“For me, it's not a big issue,” Carson answered.

“You know, I think any people can do anything they wanna do. It's just that they don't get to redefine everything for anybody else.”

“So, I'm very much Libertarian in the sense of believing live and let live. But that goes in both directions and some people don't recognize that,” he added. (The video is embedded on this page. Visit our video library for more videos.)

Last year, Carson stepped down as commencement speaker at the Johns Hopkins School of Medicine and apologized for comments related to marriage equality he made during an appearance on Fox News' Hannity.

“It's a well-established, fundamental pillar of society, and no group, be they gays, be they NAMBLA, be they people who believe in bestiality – it doesn't matter what they are – they don't get to change the definition,” Carson said, referring to the North American Man Boy/Love Association, a group which is thought to no longer exist.

Elsewhere on Larry King Now, Carson said that he is considering a presidential run.

Being president “was not on my bucket list as something as something that I really wanted to do, no. However, sometimes we're thrust into situations that are not of our choosing and we have to recognize that maybe there is a responsibility that has been handed to you by your fellow citizens.”
