I am not comparing myself to them except to say that I agree with them both on this issue that this theory holds no water, either internally or while considering the physical evidence.
Chomsky doesn't think the conspiracies are foolish? I'm not sure if you actually listened to what he says, because he quite easily blows some huge holes in the whole inside job idea.
"The rest of the evidence is kind of circumstantial, you know, odd coincidences, why didn't this happen and so on and so forth. The problem with that is that that's the kind of evidence you can accumulate about just about any complex event. I mean by that kind of evidence you could probably prove that the White House was bombed yesterday. And in fact that's why scientists do experiments in stead of taking video tapes of the world. Video tapes of the world are just too complicated, too many things happen, and you can't learn very much from them. Even in controlled experiments you find odd coincidences, unexplained phenomenon."
-Noam Chomsky, explaining why the 9/11 "truth" movement's evidence is shit.
As for Julian Assange, he said "I'm constantly annoyed that people are distracted by false conspiracies such as 9/11, when all around we provide evidence of real conspiracies, for war or mass financial fraud."
