Okay I'm sorry but before you have too much of a scare, have you tried watching any of the "conspiracy theories" on 9/11 yourself? Yes, there are lots of theories out there about silly things like Bigfoot, JFK, UFO's, and the Moon Landing, but I think this event does have a lot to say that's pretty sketchy.
No, it doesn't mean it was set-up by the Gov't or anything, I'm just saying - Some things like the Pentagon incident don't add up one bit.
I hope this doesn't get out of hand, just saying, I'd like to see more people actually look at the stuff they think is crazy. I know it's a touchy topic, it's very tragic and will not be forgotten, but, there are indeed things that people should at least try looking into.
