When Will Leading Rightwingers Denounce Violence?

U.S. Holocaust Museum guard Stephen Tyrone Johns became the latest victim of rightwing violence when he was shot and killed today by white supremacist James Wenneker von Brunn.

Johns' murder follows Kansas ob-gyn Dr. George Tiller and Pittsburgh cops Eric Kelly, Paul Schiullo, and Stephen Mayhle, all victims of rightwing hate.

When will the most prominent rightwing voices - politicians and talk show hosts - firmly denounce rightwing violence and hatred?

Update 1: Greg Mitchell visited Stormfront, the most popular neo-nazi website, and discovered lots of support for von Brunn, mixed with criticism for an attack they criticized for being ineffectual, not sufficiently deadly.

Update 2: James Ridgeway writes:

From his rather prolific writings, von Brunn's thinking seems to be indebted to two prominent white supremacists: Willis Carto of a now-defunct group called Liberty Lobby, and William Pierce, leader of the National Alliance. (Pierce died in 2002.) At least one of Brunn's books, Kill the Best Gentiles, was published by Noontide Press, which was run by Carto in the 1960s. Noontide later folded into the Institute of Historical Review, one of the major groups that denied that the Holocaust ever happened, according to Zeskind. In the acknowledgement to his book, von Brunn also lists Francis Parker Yockey, a longtime anti-Semite who was promoted by Carto, and Revello Oliver, an associate of Pierce's. In the 1960s, both Oliver and Pierce supported the presidential campaign of Alabama governor George Wallace, a staunch segregationist backed by Klu Klux Klan groups. In the 1990s, Pierce set up a National Alliance headquarters in southwestern Virginia.

In brief, the neo-Nazis with whom von Brunn associates himself  in his writings believe the Jews control the "mud people." The "mud people" are all the non-white Aryans who, in the view of the racists, ought to be kicked out of the country. A sample of von Brunn's writing (titled "Hitler's Worst Mistake: He Didn't Gas the Jews") makes some of these connections.
