Kentucky Senator Rand Paul is being criticized for saying he was not sure President Obama's views on marriage “could get any gayer.”

Paul, the son of GOP presidential candidate Ron Paul, drew laughs Friday at an event organized by the Christian conservative Iowa Faith and Freedom Coalition when he said of Obama's endorsement of gay marriage: “[C]all me cynical, but I wasn't sure his views on marriage could get any gayer.”

“It did kind of bother me though that he used the justification for it in a biblical reference,” said Paul. “He said the biblical golden rule caused him to be for gay marriage. And I'm like what version of the Bible is he reading?”

“Now that doesn't mean we need to be harsh and mean and hate people … But that doesn't mean that we have to go ahead and give up our traditions. We've got 6,000 years of tradition,” he added.

Appearing Sunday on CBS' Face the Nation, Tony Perkins, the president of the Family Research Council (FRC), chided Paul.

“I don't think this is something we should joke about,” said Perkins. “We are talking about individuals who feel very strongly one way or the other, and I think we should be civil, respectful, allowing all sides to have the debate.”

Also criticizing Paul was Republican National Committee (RNC) Chairman Reince Priebus.

“People in this country, no matter straight or gay, deserve dignity and respect,” Priebus said during an appearance on NBC's Meet the Press.
