Paul Thomas: Osama lives... and so do the lizards of Draco

The conspiracy theorist's core principle is that unless you participated in an event you can't be sure it happened, or that it happened as it's been presented to us. Thus it follows that the media, as the primary sources of misinformation, are up to their necks in every conspiracy.

Conspiracism is an assault on the idea of objective truth. Once you believe that it's sensible and reasonable to dispute all so-called facts and disbelieve the official version of everything, then it's pretty much open slather.
