Former South Dakota Sen. James Abourezk has sued proBush.com for libel for putting his name on a list of "traitors." The lawsuit is ridiculous, of course, but the words "traitor" and "treason" are getting tossed around awfully loosely these days. Ann Coulter essentially accused the entire Democratic Party of treason, but stops short when asked who should be indicted. Compare that to Christopher Hitchens' book on Henry Kissinger. When Hitchens accuses Kissinger of being a war criminal, he means exactly what he says, and he backs it up. You may not agree with him, but you can't argue that he doesn't use words seriously.
