Though the report proffers a passing reference to the First Amendment, it is replete with bias against conservative thought, writing and communications. On Page 3, law enforcement authorities are warned, "Rightwing extremist chatter on the Internet continues to focus on the economy, the perceived (emphasis added) loss of U.S. jobs in the manufacturing and construction sectors, and home foreclosures."

That is a frightening acknowledgment that political speech is being monitored in America. It is also wrong. It's not "perception." It is fact. According to the Bureau of Labor Statistics, the manufacturing and construction sectors have lost 161,000 jobs and 126,000 jobs, respectively, last month alone.

In its "Key Findings," the DHS manuscript boldly charges that "rightwing extremists may be gaining new recruits by playing on their fears about several emergent issues" and offers this warning: "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."

Under the heading "Disgruntled Military Veterans," the report alleges: "Rightwing extremists will attempt to recruit and radicalize returning veterans in order to exploit their skills and knowledge derived from military training and combat. These skills and knowledge have the potential to boost the capabilities of extremists -- including lone wolves or small terrorist cells -- to carry out violence." These unsubstantiated claims are followed by reminders that Timothy McVeigh, who bombed the Oklahoma City federal building in 1995, was a military veteran. Omitted is any reference to the fact that McVeigh was simply one of more than 40 million veterans of the U.S. armed forces.

Thirteen lines after this egregious, unconscionable slander against those of us who are military combat veterans, DHS makes the stunning charge that "lone wolves and small terrorist cells embracing violent rightwing extremist ideology are the most dangerous domestic terrorism threat in the United States."

According to this DHS "Assessment," the most dangerous threat we face here at home isn't from radical imams preaching violence in U.S. mosques and madrassas, Islamists recruiting in our prisons, Somali terrorists enticing young immigrants to become suicide bombers, or Hamas, Hezbollah or al-Qaida operatives plotting mass murder. No, according to DHS, the real threat comes from what our government labels "rightwing extremist ideology."

Mr. Obama should disavow this report publicly and fire the officials responsible for issuing it. Those who prepare his remarks for the occasion should insert in the teleprompter former Sen. Barry Goldwater's words on the subject: "Extremism in the defense of liberty is no vice."
