COMMENT: As one who has studied fascism for decades and, as a result, been exposed to Nazi theory and culture, encountering the “Truthers”  has proved seductive and challenging.
After reading of “subhumans,” “life unworthy of life,” “useless bread gobblers” and the like, one should not be exposed to the “controlled demolition of the World Trade Center,”  “cruise missile hit the Pentagon” freaks.
At times, I now think that, perhaps, the Third Reich had the right string, but the wrong yo-yo. Instead of “the Final Solution to the Jewish Problem,” or gassing gays, gypsies, the elderly, disabled and seriously ill, perhaps simply killing off stupid people might have significantly improved society.
Perhaps a “Final Solution to the ‘Truther Problem'” is indeed what is called for. “Kill ’em all, let David Ray Griffin sort ’em out!”
(Predictably, the “Truthers” rely on anecdotal evidence, and don’t take into account the fundamentals of a controlled demolition. FTR #599  debunks the notion, featuring a paper by Brent Blanchard, one of the top engineers in the field. Supplementing that, I recommend Item #3 at this website . Produced by Brent Blanchard’s firm, it shows the implosions of many buildings. In numerous programs, recorded and live, I’ve repeatedly noted that, before an implosion can be done, the targeted building must be gutted, with I-beams, staircases and entire floors, in some cases, removed prior to the implantation of the charges. Otherwise, the building won’t “implode”! Check out the buildings here–they have been gutted! That is NOT the case with ANY of the WTC buildings. Not the Twin Towers, not WTC 7. Item #13 at this same site  offers a more measured view of this, due to the placement of the video camera and the background lighting.)
The only significant accomplishment of the Truther milieu is to help obscure the very real, demonstrable links  between the GOP and the Bush administration  and the individuals and institutions  involved in financing Al-Qaeda, Hamas and Palestinian Islamic Jihad. This is on the public record, available from public media sources. When was the last time you heard a Truther discuss Operation Green Quest? 
Instead of languishing in a cell at Guantanamo, GOP bigwig Grover Norquist  is actively obstructing efforts to implement the tax increase required to get America’s budgetary house in order. (Norquist was one of the architects  of the Bush/GOP/Muslim Brotherhood axis exposed by the Operation Green Quest investigations .)
The Truthers have also succeeded in eclipsing the, heroic, important work done by Daniel Hopsicker on the intelligence and organized crime connections to the flight school milieu through which Atta and company infiltrated the U.S. When was the last time you heard a Truther discuss Huffman Aviation, Rudi Deckers or any of what Daniel has researched?
Another casualty of their collective folly is the investigation that should have been conducted into Ptech, the Muslim Brotherhood-controlled firm that designed the threat assessment software for the Air Force, NORAD and other federal agencies. When was the last time you heard a Truther discuss Ptech?
Among the most important and most neglected aspects of the investigation concerns SICO , the Swiss-based holding company for the Bin Laden family’s interests. When was the last time you heard a Truther discuss SICO?
After floating the preposterous notion that explosives were used to bring down the Twin Towers, the “Truthers” have attempted to retreat to the quaint notion that thermite or nano-thermite were used to bring down the towers.
That, too, has collapsed like the towers themselves.
