The Southern Poverty Law Center published a new report this week on 30 up-and-coming leaders of the radical right. There are some old familiars on the list, like David Duke, and many others who probably won't come as much of a surprise to regular Mother Jones readers. SPLC singles out some of the chorus of anti-Muslim activists like Pam Geller, Frank Gaffney and David Yerushalmi as people to keep an eye on. There are some gay-bashers in there, too. Birther-conspiracy theorist Joseph Farah, the founder of WorldNet Daily, also makes the list. But not everyone on the group seems to rise to the level of menace that SPLC suggests.Among those might be Mike Vanderboegh, a former militia activist from Alabama. Vanderboegh is probably most famous these days for having encouraged readers of his blog to break the windows of Democratic Party headquarters after the passage of health care reform, which prompted some of his readers to toss bricks through the windows of a few Democratic congressional offices.Vanderboegh, though, is a bit more of a complicated character than the SPLC has made him out to be. His rhetoric is certainly inflammatory, but it's also mostly confined to his blog, which has a very small following. Vanderboegh has also helped bring to light some evidence of wrongdoing on the part of the government in the "Fast and Furious" gun scandal, in which the federal government allowed guns to be illegally exported to Mexico in the hopes of tracking them to major drug cartel leaders. (The ATF agents ended up losing track of thousands of the guns, which later turned up at crime scenes in Mexico and the US.) He's also got a sense of humor, a rare quality in an extremist. He responded to his inclusion on the list by writing a blog post about it that included a photoshopped picture of Mark Potok, the SPLC senior fellow who tracks right-wing extremism, wearing a tin-foil hat.
