What exactly is a weak conspiracy theory? Is this a new Skeptic term? It was not only the lies about WMD, but it also included falsehoods about Saddam's links to Osama and Al-Qaeda. This false narrative was widely believed by the American people. This would seem like a strong conspiracy theory to me. Plus, it led to the complete decimation of an entire country. This seems a lot more consequential than someone wondering if the moon landings were faked.
Is this really what they had in mind?
"The building was designed to have a fully loaded 707 crash into it. That was the largest plane at the time. I believe that the building probably could sustain multiple impacts of jetliners because this structure is like the mosquito netting on your screen door -- this intense grid -- and the jet plane is just a pencil puncturing that screen netting. It really does nothing to the screen netting".
Frank DeMartini, WTC Project Manager
A white paper in the files of the Port Authority state,
"The buildings have been investigated and found to be safe in an assumed collision with a large jet airliner (Boeing 707—DC 8) traveling at 600 miles per hour. Analysis indicates that such collision would result in only local damage which could not cause collapse or substantial damage to the building and would not endanger the lives and safety of occupants not in the immediate area of impact."
So "fully loaded", "large jetliner" and "600mph" implies small planes, not fully loaded and traveling slow. Skeptics are best at semantics.
Of course, to say that the buildings "collapsed" is really a misnomer. The official explanation is "crush-down crush-up."
So you are admitting that the highly loaded term "conspiracy theory" is meant only to apply to people questioning official narratives. Thus a "conspiracy theory" is not necessarily a false belief, it is just a contrary one to the powers that be.
