Yes, because legend has it that's where the term "moonbat" derived. It's been discussed on a number of other threads, and is mentioned on Monbiot's Wikipedia page:
The pejorative political epithet "Moonbat" is often used by right-wing political commentators to mock Monbiot.[10] The epithet was coined in 2002 by Perry de Havilland of Samizdata.net, a libertarian weblog. The claim that the term was originally used as a play on Monbiot's surname [11] has been denied by de Havilland - the full epithet being "barking moonbat". Seemingly, George himself does not mind.[12]
My head swells ever more. I will one day own the entire blogosphere. Great minds think alike, and all that...
