So he's a godless liar. Not only does he lie about what FemiNazi means, he lies about the endorsement, because Limbaugh doesn't endorse candidates.
It's been many years now, but I recall that he flew out to speak at John's announcement of his candidacy. Without recalling what he said, that could be construed as an endorsement.
The atheist said: “Limbaugh endorsed Carlson for governor...”
Mr. Silverback responded: “So he’s a godless liar. . . he lies about the endorsement, because Limbaugh doesn’t endorse candidates.”
Michelle Malkin begs to differ with you: “One glimmer of sunshine for the GOP was an end-of-summer rally in which talk-show giant Rush Limbaugh endorsed Republican gubernatorial candidate John Carlson.”

Disagree with the atheist on the pledge, but get your facts straight. Whether you want to apologize for your false accusation is up to you.
