Vanity question.

Cross of being a "lunatic" and having "bats in one's belfry."

[West Coast Conservative]

Moonbat is a pejorative political slogan coined in 2002 by Perry de Havilland of "The Libertarian Samizdata," (http://www.samizdata.net/blog/) a libertarian weblog. [1] (http://www.samizdata.net/blog/archives/000615.html) The term enjoys great currency in the libertarian blogosphere, where it is used to disparage modern liberals, peace protestors, and other ideological opponents.

What is the origin of the term "moonbat?"

I don't know the answer to the question, but I DO know that I'm being followed by a moon shadow

I prefer "barking moonbat" myself. ;-D

[FormerACLUmember]

"Barking moonbat" was the original usage.

Barking moonbat (definition) noun. Someone on the extreme edge of whatever their -ism happens to be.

In re a reference you might find interesting:

Monbiot

I'm wagering "moonbat" came from a very fascinating debate between Libertarian and "Monbiot".

Monbiot is a raver for "social change" and one world order. In England. You might check out what this guy, Mr. Socialist, says. Yep. He's a Moonbiot.
