No need to apologize Hxtr, but calling somebody ignorant that doesn't agree with you is well, just ignorant. There will never be any shortage of those who see a conspiracy, and frankly regardless of whether there was or wasn't, none of us will ever have the power to do anything about it so I don't let it keep me awake at night.
The main reason I don't think 9/11 was a conspiracy is because thousands of people would need to be involved to pull it off, and it's just human nature to talk about things or take an incriminating picture, and I don't feel that so many people could have possibly kept that secret with so many people dead on US soil. The Kennedy assassination is about the only thing I feel "could" have been a conspiracy, and only because it would have taken a few people to pull it off, and several of the players died mysteriously just after Kennedy was killed. When Eisenhower left office he warned of the "military-industrial complex". Kennedy was looking for ways to get out of Vietnam and the main players behind the military industrial complex were looking for ways to expand. Kennedy was in the way, and they knew that Johnson wouldn't hesitate to put boots on the ground in Vietnam which he did. But like I said before, I can't prove or do shit about it so I don't lay away nights thinking about it.
