Oh,
PLEASE! Stop calling what happened on 9/11 a "tragedy" over and over again, as if it's a sacrilege to talk about conspiracy theories surrounding that infamous day.
Yes, it was a "tragedy" for the people who died and those who knew them, their friends and families and so forth, but the world desperately NEEDS to get over itself, to get over it's initial trauma and start looking at the facts objectively.
9/11 WAS a scam, because people knew about it ahead of time and did nothing because it suited their personal interests, while others made it happen secretly and blamed others afterwards, the usual bunch of scary foreigners from overseas, and they ALL profited vastly from these terrible events.
And need I remind you that the "official" version of the story is a
conspiracy theory as well, but since it's the government's version people in general simply say "Well, it must be the truth, our dear elected leaders wouldn't LIE to us, would they? They wouldn't exploit us like this, would they?", while independent investigators are riduculed by the voluntarily ignorant masses merely out of blind faith.
God bless America, I suppose.
