This was meant to be sarcastic, but it seemed to unsettle a few of them. ;) With time, they seemed to realize that loose change was mostly a piece of crap, but they still clung to some of the theories (especially about the Pentagon).
Over the months that I have engaged in debates with these folks, I have begun to believe that some of them are actually neo-nazis. I could be wrong about that, of course, but it occurred to me that their obsessive hate for Bush and Israel combined with their love for 9/11 conspiracies almost makes them sound like modern day democrats.
Neo-Nazis and Islamo-Fascists are two birds of a feather, so you may have a point there.
