Ron Paul's alleged anti-gay stances have riled MSNBC's Ed Schultz.

Schultz on Thursday devoted a segment of his The Ed Show to criticize Paul, who has surged in many Iowa polls to second place just days before voters head to caucus on Tuesday.

Schultz chided Paul for boasting of the endorsement of Rev. Phil Kayser on his campaign website, then quietly scrubbing the page.

Kayser is the controversial pastor of the Dominion Covenant Church in Omaha, Nebraska who believes gay sex should be criminalized and unrepentant offenders should face the death penalty.

“This would have a tendency of driving homosexuals back into their closets,” he wrote in his 2009 book Is The Death Penalty Just? “I think I have demonstrated how even capital punishment can be restorative.”

On the show, Schultz and guest Mike Rogers, managing director of RawStory.com, blasted Paul for the move.

Schultz said Kayser made “extremists look tame by comparison.”

Rogers argued that the Texas Representative wants “to free up states to be able to do things like this reverend wants,” including “basically make being gay illegal if [Texas] wanted to.”

“I think he's feeding the fire and knows what he's doing with that,” Rogers added.
