Conservative celebrity and potential presidential candidate Ben Carson warned gay couples against pushing baker opposed to gay marriage, saying it isn't “smart.”

According to The Hill, Carson received a standing ovation after delivering his remarks at the Iowa Freedom Summit organized by Iowa Rep. Steve King.

But the former Johns Hopkins University pediatric neurosurgeon and Fox News commentator “struggled at times through a post-speech press availability, offering vague answers on a number of topics and refusing to answer how he thinks abortion should be criminalized,” the outlet reported.

Referring to recent headlines about bakers getting sued for refusing to serve gay couples, Carson said: “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.”

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.”
