SIEGELISM. Matt says he agrees. But it's easy to agree that all these young kids and their insouciant fashion statements make you mad. Matt's 25 now, and I'm sure in three years, I'll agree, too -- there appears to be a schedule for these sorts of opinions. For that reason, the question isn't whether he agrees with Siegel's banal crankiness, but his proposed remedy. "When I see someone wearing a baseball cap in a movie theater," Siegel writes, "I want them to bring back the guillotine." Siegelism in action -- take a mundane point (I don't like bloggers or baseball caps) and go for the wild overreach (they're fascists or we should execute cap wearers). When agreeing with Siegel, the question isn't the underlying opinion, but the overlay of nuttiness.
