Well, that may be true in your world, but in the real world paranoia, especially paranoid delusions, are NOT synonymous with the truth. Paranoia has a tendancy to color the truth. In the case of most truthers, this paranoia is so severe that it becomes paranoid delusions where the paranoia is so great that the truther starts actually believing delusions that have no basis in reality. Sometimes truthers even recognize other truther's delusions such as when you tried to call out Fetzer on some of his delusions. Apparently even people suffering from paranoid delusions can see other people's delusions even while being unable to see their own.
Then he starts in with the tired claims about buildings (in some general sense) not collapsing due to fires and the cause of the WTC7 collapse being "mysterious." Man, I'm tired of people basing their suspicions on their own ignorance of how the collapses happened. They've been understood and explained quite well enough, but for those who can't wrap their heads around it, the information and theories that we have just aren't good enough. They're like creationists who deny evolution simply because they don't understand that theory, AND because they have some emotional interest in believing otherwise. For conspiracists and creationists alike, it always seems to come down to plain bias + (willful) ignorance.
