According to Dave McMillion, "Republican W.Va. gubernatorial candidate gets in hot water over 'joke'", Herald Mail 5/12/2011:
Former Berkeley County delegate and current Republican gubernatorial candidate Larry Faircloth said Thursday that a joke he told referring to President Obama as "Sambo" and House Minority Leader Nancy Pelosi as a "bimbo" was simply an attempt to "bring a little humor" to the campaign. […]
"There's nothing racist or feminist about me," Faircloth said in a telephone interview Thursday afternoon.
Poor Mr. Faircloth. Just when you think you've got English derivational morphology figured out, it sneaks up and clobbers you.
Of course, it's likely that he knows perfectly well what feminist means, and was simply afflicted by one of those word-substitution errors that happen to all of us from time to time. Or the substitution might be the work of Mr. McMillion, who was the only witness.
A similar slip of the tongue is presumably what happened to President Obama on May 10, when he observed that
Internationally, we've gone through a Teutonic shift in the Middle East that could have enormous ramifications for years to come.
Neither for Mr. Faircloth nor for Mr. Obama do we have a recording to show that this was a genuine slip of the tongue (or mistaken grasp of the English language) rather than a mis-transcription. But both of these substitutions are plausible ones: feminist and sexist are both adjectives in -ist, whose stems are similar in meaning; teutonic and tectonic are both adjectives in -ic, whose stems are similar in sound and spelling.
