I hate the term "conspiracy theory." Why do people have such a hard time believing our government lies to us? Even though I like Pres. Obama, I have no illusions that he's already lying to me. That is what governments do.
Was 9-11 a fabrication? Does Al Qaeda really exist? What is wrong with asking those questions? One of our major problems is that we are a society of complacency. As long as we can drive our SUV's to the gas station and fill up, and then drive to Wal Mart and buy all the useless crap we want......we just don't care. Deeper than that, we don't want to care.
There are a lot of indicators that things don't add up with the official 9-11 story......but we don't want to hear that. If that was the case then something is deeply wrong with our government and our lifestyle. That means we might have to make some drastic changes, and the average crispy cream American cannot handle that idea. It makes their brain melt. It's the same reason so many on the right are so desperate to discount global warming.
