Of course, almost all the statements listed are about controlled demolition. The author's tone so bitter and vicious. Of course, it's accepted to show that kind of derision towards the truthers.

Carl Sagan's Son Is a 9/11 Truther
http://gizmodo.com/carl-sagans-son-is-a-9-11-truth...
Carl Sagan is arguably science's biggest rockstar—the ultimate champion for logic and reason. Which makes it all the more painful to find out that his son is a vehement 9/11 truther.
Perhaps even more surprising than Jeremy Sagan aligning with the paranoid ranters of the world is the fact that, apparently, the apple doesn't fall far from the tree. No, not Carl Sagan (dear god not Carl Sagan). We're talking about his mother. Yes, Lynn Margulis, Jeremy Sagan's mommy dearest herself was also a crusader for 9/11 Truth.
