The article explains:
"A key difference this time is that the federal government — the entity that almost the entire radical right views as its primary enemy — is headed by a black man. That, coupled with high levels of non-white immigration and a decline in the percentage of whites overall in America, has helped to racialize the Patriot movement, which in the past was not primarily motivated by race hate. One result has been a remarkable rash of domestic terror incidents since the presidential campaign, most of them related to anger over the election of Barack Obama. At the same time, ostensibly mainstream politicians and media pundits have helped to spread Patriot and related propaganda, from conspiracy theories about a secret network of U.S. concentration camps to wholly unsubstantiated claims about the president's country of birth."

Currently, the government is looking into a YouTube video posted by suspected militia members threating the government with reprisal by war.
