For conspiracy theorists, truth is less about fact and more about what they want to believe.
I believe that extra terrestrials probably exist. I just don't believe any of them have ever been here. I believe that 9/11 was an inside job — inside Al Quaeda, that is. I believe the global warming hoax is... well... a hoax. I believe J.F.K. was assassinated by an American — just not one working for the CIA. I believe NASA's moon landings were faked for the HBO specials in 2001, but not in 1969. I believe that the world will end in 2012 for somebody, but the rest of us will be fine. Conspiracy Theories are utter nonsense, and I am about to demonstrate why.
