Citing his anti-gay rhetoric, the Southern Poverty Law Center (SPLC) has placed conservative celebrity Ben Carson on its “extremist watch list.”

The former Johns Hopkins University pediatric neurosurgeon turned Fox News commentator has previously brushed aside speculation that he's planning a 2016 bid for the White House. But two months ago he suggested that God has been nudging him along.

“I feel fingers,” he said in response to CBN News' David Brody's question, “How is that conversation going with God about this potential presidential run? Has He grabbed you by the collar yet?”

“May I potentially see you [on the presidential campaign trail] soon?” Brody asked.

“I think there is a good chance you might,” he answered.

In 2013, Carson stepped down as commencement speaker at the Johns Hopkins School of Medicine for linking marriage equality to bestiality and pedophilia, which drew a loud outcry from students and faculty. In apologizing, Carson said people had “taken the wrong meaning out of what I was saying.”

More recently, he suggested that bakers opposed to marriage equality might poison the wedding cakes of gay couples.

“What I have a problem with is when people try to force people to act against their beliefs because they say 'they're discriminating against me.' So they can go right down the street and buy a cake, but no, let's bring a suit against this person because I want them to make my cake even though they don't believe in it. Which is really not all that smart because they might put poison in that cake.”

The SPLC specifically cited Carson's anti-gay rhetoric in his “extremist files” profile.
