At the New York Times, William Safire is looking for the origin of the term “moonbat:” Blargon. (Hat tip: Michael.)

The prevailing put-down of right-wing bloggers is wingnuts; this has recently been countered by the vilification of left-wing partisans who use the Web as moonbats, the origin of which I currently seek.

First use at LGF, in August 2002: lgf: raving moonbat watch. More information is available at zombie’s LGF Dictionary.

moonbat - An unthinking or insane leftist — in other words, most modern leftists. Moonbat can also be used as an adjective, e.g. a moonbat professor. According to the Wikipedia entry for moonbat, the word was coined in 2002 by the Editor of Samizdata, Perry de Havilland, and was a variation on the name of radical British activist and columnist George Monbiot. Originally, the term “moonbat” was intended to be more politically neutral, and described wackos on the left and the right, but it quickly acquired its current usage of being applied almost exclusively to those on the left. The term also references the moon much in the same way that “lunatic” refers to the insanity-causing powers of the full moon (luna = moon). LGFers occasionally analyze the behavior patterns of various moonbat “species” as if they were actual animals, and even give them satirical Linnaean taxonomical names, such as moonbattus berkeleyensis. According to Charles: “Moonbat was originally coined by Perry at Samizdata, I believe. But LGF probably played a much bigger part in popularizing it.” The entry in the Samizdata glossary indicates that Perry originally coined the full phrase “barking moonbat”; apparently “moonbat” is just a subsequent shortened version of “barking moonbat,” rather than being a pre-existing term that was lengthened to barking moonbat.
