Dr. Ben Carson has fired back at the left after he was heavily criticized for his recent comments on gay marriage. A group of medical students at Johns Hopkins University wanted him replaced as commencement speaker after he said the following last week on Hannity.

“My thoughts are that marriage is between a man and a woman. 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."

He later apologized, but said his remarks were misconstrued.

On Mark Levin's radio show Monday, Carson accused his white liberal critics of displaying racism.

“They’re the most racist people there are. Because they put you in a little category, a box: 'You have to think this way, how could you dare come off the plantation?'” said Carson, arguing that liberals "need to get rid of" him because he represents an "existential threat."

Bob Beckel said Carson's statements are absurd, likening them to "someone calling Eric Bolling a Communist." He also disputed the notion that Democrats are fearful of Carson politically.

Andrea Tantaros disagreed, saying she thinks somebody like Carson is "deeply threatening to the left." She pointed out the fact that Carson overcame poverty to become a brain surgeon "and it had nothing do with the government, and he loves God too."

Dana Perino sided with Beckel's statement that Democrats do not "lose sleep" over Carson's political prospects. She believes he is spending too much time in the spotlight, appearing on too many talk shows in recent months.

"He's everywhere at all times. If cable news punditry and talk radio shows were a great way to cut a path to political success, we would probably not have President Obama here now," said Perino.
