Conservative radio talk show host Rush Limbaugh went after Fox News’ Bill O’Reilly on Wednesday for saying opponents of same-sex marriage don’t have a “compelling” argument other than “thumping the Bible.”

O’Reilly’s comments came after Megyn Kelly claimed the argument against gay marriage is not very strong during his show Tuesday night. She said she has yet to hear a compelling argument against same-sex marriage other than religious beliefs.

“The compelling argument is on the side of homosexuals,” O’Reilly agreed. “That’s where the compelling argument is: ‘We are Americans. We just want to be treated like everybody else.’ That’s a compelling argument. And to deny that you’ve got to have a very strong argument on the other side. And the other side hasn’t been able to anything but thump the Bible.”

The latter part of O’Reilly’s remarks is what Limbaugh took exception to. He said the Fox host “marginalized” a good portion of his audience and even referred to him as “Ted Baxter,” the vain, buffoonish TV news anchor from the Mary Tyler Moore Show.

“How many of you who watch Fox are ‘Bible thumpers’? Do you think there are any Bible thumpers, quote-unquote, that watch Fox? Because last night you were sort of marginalized on ‘The Factor’ as not having a compelling argument and just being a bunch of Bible thumpers,” Limbaugh said.
