There's been a disturbing trend on the internet recently of people who actually believe that 9/11 was faked.
Yes, you heard that right. And these people are serious. And they think they have irrefutable proof. And they will proselytize their beliefs with all the fervor of a Scientologist at a Hollywood convention.

this blog post for a basic summary of their beliefs. And try not to get sucked in by the "evidence." I've been following every sickening turn in this story (and for my troubles I got a 9/11 conspiracy theorist on my forum to deal with), and I can guarantee you that every piece of "proof" they come up with may seem convincing at first but is actually very easily refuted by a little common sense and digging.
For example, many nutjobs claim that dozens of cell phone calls were made from the airplanes even though that's impossible to do in an airplane. Problem is the planes were flying way below regulations. That was the whole point. Oh, and 96% of the calls were made using the airplane phones, not cell phones.
Anyway, I just wanted to alert you all to this rather sad segment of society and urge you all to do the best you can to shut them up. Their letters are actually starting to show up in mainstream news sources and that's really very alarming.
