SPLC's Mark Potok warns that radical right, extremist groups are on the rise. These groups are fueled by racism, especially anti-immigrant racism and rage at the nation's first African American president, Barack Obama, he says.
"Furious anti-immigrant vigilante groups soared " during 2009," Potok writes.
Violent militia groups who had their "heyday" during the 1990s, including in the Oklahoma City bombing, have reemerged, according to SPLC's research.
"Already there are signs of similar violence emanating from the radical right. Since the installation of Barack Obama, right-wing extremists have murdered six law enforcement officers," Potok writes.
He points out a growing "cross-pollination between different sectors of the radical right not seen in years," with more cooperation on agendas and ideologies.
Such "cross pollination" may have been at work with the Hutaree group. The media reports Hutaree members contacted another Michigan militia member for help, which he claimed he declined giving.
Hutaree promotes extremist ideas that have found wide acceptance among right-wing political movements, including the Republican Party.
At the GOP's 2009 Senate-House fundraising dinner, actor Jon Voight got a rousing ovation when he called Obama the "false prophet" in a heavily Armageddon-rhetoric-laden speech.
Similar rhetoric is seen in the tea party movement.
