Who cares about whether 9/11 was an inside job, the non-conspiratorial fact remains that it served as a great excuse to get into Iraq. Let's change discussion to the REAL conspiracies.
Of course it was an inside job. To prepare for a war, the most important thing to do is severely disrupt the Pentagon.
The people who say that belong together with the Holocaust deniers.
One can make equally logical arguments that God exists or not. The question hasn't been decided in millennia and never will. But I should note that the late science fiction author Keith Laumer, who was not a religious man, has commented that what we know is what people in authority tell us. In the past, we
knew that the Earth was flat and the Sun and planets went around it. How? It's what our family and people in authority told us. How do we know that the Earth is round and we travel around the Sun and that the speed of light is 186,282 miles per second? We're taught that in school. Most of us don't have the time, cleverness, or resources to check these things for ourselves.
Conspiracy theorists, from my personal experience, are people who like to think they are smarter than everyone else and aren't. They think they have THE knowledge about how things really work and what really happened. Not only smugness but wishful thinking drives these people.
Kennedy was assassinated by the CIA because he was going to end our involvement the Vietnam War. (Reality: political analysts deny this, plus it would have been a moot point. JFK already had a fatal case of Addison's disease and was about to kick the bucket anyway.) Bush stole the 2000 election. (Reality: The Supreme Court merely decided on the validity of the votes in Florida. As lifetime appointees, no politician can influence them.) 9/11/01 allowed Bush to invade Iraq. (Reality: There was nothing to stop him from doing it anyway.) There's a secret organization called OPEC who...oh wait, people know about it already?
Oh, there are real conspiracies, but less that one tenth of one percent of conspiracy theories out there are valid. And the valid ones are no secret to the public.
