Because only an asshole would believe it without any supporting proof!
They say it's "impossible" for plane parts to have travelled through the central core of the WTC North tower.
Not so.

"Fig 1. World Trade Center's first 110-story tower is already up to 10th floor level above grade; excavation is almost complete.")[3]
The core was dense, but not impenetrable. As the plane severed columns on its way in at a high rate of speed, the possibility of plane parts continuing through the core, and out the other side is far more plausible than any alternative explanations. Objects in motion tend to stay in motion until some countervaling force acts upon them (Newton).
These agents of bullshit -- whether neocon ideologues, or willing dupes -- are extremely aggressive and prevalent all over the Internet now. They are actively "poisoning the well" of legitimate discussion of September 11th 2001 with their endless and ridiculous disinformation.
Who benefits?
Meet the Masters of Disinfoland
The "Scholars for 9/11 Truth" group has a history that casual observers might not realize. Originally formed to legitimize the study of September 11th anomolies (or was it?) by PhD's and other academics in the related fields, the organization was of course vulnerable to infiltration.
James H. Fetzer PhD. "wrote the book" on disinformation [6]. In Fetzer's study of the ways of twisting the truth and delegitimizing your opponent, he revealed many of the disengenuous techniques that he himself later used against his fellow scholars in the 9/11 Truth Movement [7].
Fetzer's control of the Scholars group/website led to its eventual breakup. The "Scholars" website suddenly started entertaining nonsense theories, under the guise of legitimate scientific inquiry. The group imploded in December 2006 with the promotion of the "directed energy beam" hypothesis by Judy Wood PhD., and the subsequent retirement of Dr. Steven Jones PhD. from the group.
Steven Jones went on to start up a second group, Scholars for 9/11 Truth AND JUSTICE. Jones smartly retained editorial control of the Journal of 9/11 Studies (much to Fetzer's dismay) which publishes related papers.
The "directed energy weapons" garbage was at the root of most of this controversy.
Fetzer:
"I am inviting Judy Wood to organize a panel discussion on non-conventional means, including high-tech directed energy weaponry, that might have been used to destroy the World Trade Center." -James Fetzer, Scholars for 9/11 Truth website, December 2006
Add to that an attempt to legitimize the "no planes" claptrap:
