Conspiracy theories require no thought to start, and no IQ to beleive. Consequently, they abound in the modern world.
All the 9-11 theories I have seen on TV, or the paper, or the radio, or the internet have been beyond laughable. Its almost as f*** up as watching people tear through the woods with a camera looking for evidence of Bigfoot, but at least thats humorous.
...oh yes, and the moon landing folks, they get off thinking they are smarter than everybody else (thats the appeal), and are also a bunch of losers. Every time I see one interviwed its some wild eyed nut living in a trailer park.
