To those of you who insulted me above, basically calling me dumb, I see this is more of an emotional issue than a scientific one.
Nothing I wrote insults you nearly as much as what you wrote above. If you mean it, then frankly I wasn't condescending enough. Whether the 9/11 attacks were orchestrated by a bunch of pissed-off Muslims or the US government or the Illuminati or the reptilian overlords is purely and entirely a scientific issue. How you feel about it doesn't alter the facts one iota.
I may have been more scathing of your ridiculous claims than necessary as it's really not your fault that I've heard them hundreds of times before. However, it is your fault that you choose to believe the nonsense spouted by conspiracy theorists even when you are presented with evidence contradicting those beliefs. You just don't get to have your opinions respected when they're so undeserving of respect.
