Whether you believe it's a just or an unjust war is moot. Pasting a slogan like "No Blood For Oil" or the less visible "Thanks Exon" on a car (Maza MPV V6) that gets 18mpg in the city, or, for that matter, on any gas burning vehicle, seems just a wee bit hypocritic to me. There are at least a couple dozen folks like this cruising around Berkeley; this is the first one I actually caught parked.
