Is Right-Wing Extremism Rising Because of the Economy?

From a recent report by the Department of Homeland Security: "The consequences of a prolonged economic downturn—including real estate foreclosures, unemployment, and an inability to obtain credit—could create a fertile recruiting environment for rightwing extremists and even result in confrontations between such groups and government authorities similar to those in the past." Is right-wing extremism on the rise in the U.S.? Are some conservatives wrong, as Robert Schlesinger writes, to see the report as an attack "specifically timed to counter the 'Tea Party' movement"? Post your thoughts.
