Conspiracy theory boils down to one essential principle: Everything supports the theory.
Lack of evidence is some of the best evidence. It proves how high and deep the conspiracy goes, because they can cover it up so well. So lack of solid evidence proves concealment. If you can't find it, it's just really well hidden, because WE KNOW IT'S THERE. It DEFINITELY EXISTS.
Evidence against the conspiracy is disinformation. Scientific explanations of phenomena are junk science. It's all just public relations produced by shills working for the conspiracy.
Any unexplained event or phenomenon is not the work of natural principles you are unfamiliar with. It is ONLY the work of sinister forces.
Anyone who disagrees with the conspiracy theorists is a dupe. Yet unswerving belief IN the conspiracy does not make you THEIR dupe. No, you are one of the intelligent faithful who see through all the smoke and mirrors and pesky "science" produced by the conspiracy to cover up their heinous schemes.
