once, at p.3. The rest folows the lead "Leftwing Extremists Likely to Increase Use of Cyber Attacks over the Coming Decade."

And, yes, I am aware of ELF et al's other activities - since we just had one sentenced in Fed DC in Marquette 3 weeks ago - and of the 7 May 2008 DHS report cited by Bourbon just below my post.

That report sums their violent incidents from 1984-2008 (table - pp.15-23); and amply supports concern.

The Rightwing Extremist lead "Rightwing Extremism: Current Economic and Political Climate Fueling Resurgence in Radicalization and Recruitment" is supported by these items in this century (from report):

p.3
The DHS/Office of Intelligence and Analysis (I&A) has no specific information that domestic rightwing* terrorists are currently planning acts of violence, but rightwing extremists may be gaining new recruits by playing on their fears about several emergent issues.

(U//LES) Threats from white supremacist and violent antigovernment groups during 2009 have been largely rhetorical and have not indicated plans to carry out violent acts.

p.4
(U) A recent example of the potential violence associated with a rise in rightwing extremism may be found in the shooting deaths of three police officers in Pittsburgh, Pennsylvania, on 4 April 2009. The alleged gunman’s reaction reportedly was influenced by his racist ideology and belief in antigovernment conspiracy theories related to gun confiscations, citizen detention camps, and a Jewish-controlled “one world government.”

p.5
Most statements by rightwing extremists have been rhetorical, expressing concerns about the election of the first African American president, but stopping short of calls for violent action.

p.6
In April 2007, six militia members were arrested for various weapons and explosives violations. Open source reporting alleged that those arrested had discussed and conducted surveillance for a machinegun attack on Hispanics.

— (U) A militia member in Wyoming was arrested in February 2007 after communicating his plans to travel to the Mexican border to kill immigrants crossing into the United States.

p.8
A prominent civil rights organization reported in 2006 that “large numbers of potentially violent neo-Nazis, skinheads, and other white supremacists are now learning the art of warfare in the [U.S.] armed forces.”

The FBI noted in a 2008 report on the white supremacist movement that some returning military veterans from the wars in Iraq and Afghanistan have joined extremist groups.
The report also notes one post-1995 event:

p.6
Law enforcement in 1996 arrested three rightwing militia members in Battle Creek, Michigan with pipe bombs, automatic weapons, and military ordnance that they planned to use in attacks on nearby military and federal facilities and infrastructure targets.
To me, this seems very slim evidence on which to posit a resurgence.

To these, the report adds another factor - firearms:

p.3
(U//FOUO) The possible passage of new restrictions on firearms and the return of military veterans facing significant challenges reintegrating into their communities could lead to the potential emergence of terrorist groups or lone wolf extremists capable of carrying out violent attacks.

(U//FOUO) Proposed imposition of firearms restrictions and weapons bans likely would attract new members into the ranks of rightwing extremist groups, as well as potentially spur some of them to begin planning and training for violence against the government. The high volume of purchases and stockpiling of weapons and ammunition by rightwing extremists in anticipation of restrictions and bans in some parts of the country continue to be a primary concern to law enforcement.

pp.4-5
(U) Legislative and Judicial Drivers

(U//FOUO) Many rightwing extremist groups perceive recent gun control legislation as a threat to their right to bear arms and in response have increased weapons and ammunition stockpiling, as well as renewed participation in paramilitary training exercises. Such activity, combined with a heightened level of extremist paranoia, has the potential to facilitate criminal activity and violence.

— (U//FOUO) During the 1990s, rightwing extremist hostility toward government was fueled by the implementation of restrictive gun laws—such as the Brady Law that established a 5-day waiting period prior to purchasing a handgun and the 1994 Violent Crime Control and Law Enforcement Act that limited the sale of various types of assault rifles—and federal law enforcement’s handling of the confrontations at Waco, Texas and Ruby Ridge, Idaho.

— (U//FOUO) On the current front, legislation has been proposed this year requiring mandatory registration of all firearms in the United States. Similar legislation was introduced in 2008 in several states proposing mandatory tagging and registration of ammunition. It is unclear if either bill will be passed into law; nonetheless, a correlation may exist between the potential passage of gun control legislation and increased hoarding of ammunition, weapons stockpiling, and paramilitary training activities among rightwing extremists.

(U//FOUO) Open source reporting of wartime ammunition shortages has likely spurred rightwing extremists—as well as law-abiding Americans—to make bulk purchases of ammunition. These shortages have increased the cost of ammunition, further exacerbating rightwing extremist paranoia and leading to further stockpiling activity.

Both rightwing extremists and law-abiding citizens share a belief that rising crime rates attributed to a slumping economy make the purchase of legitimate firearms a wise move at this time.

(U//FOUO) Weapons rights and gun-control legislation are likely to be hotly contested subjects of political debate in light of the 2008 Supreme Court’s decision in District of Columbia v. Heller in which the Court reaffirmed an individual’s right to keep and bear arms under the Second Amendment to the U.S. Constitution, but left open to debate the precise contours of that right. Because debates over constitutional rights are intense, and parties on all sides have deeply held, sincere, but vastly divergent beliefs, violent extremists may attempt to co-opt the debate and use the controversy as a radicalization tool.
When the yellow bird sings in the coal mine, I listen up.

BTW: My words quoted in your post were frankly intended to be sarcastic. You, as a reader, have the right to your perception (and expression of that perception) that it is "spin"; or that it is a form of "juvenile partisan bickering"; or whatever.

The same goes for your perception that DHS has been balanced in its reporting. The readers can access the 2008 & 2009 DHS "leftwing" reports and can judge whether the evidence in those reports supports the DHS conclusions. They also can judge whether the evidence in the 2009 DHS "rightwing" report supports the DHS conclusions there.
