I believe that each conspiracy theory is true in a really mundane way. At least the government ones... the satanic sex cults exist, but most of the followers think its some type of cultural thing, until they are thoroughly brainwashed/blackmailed, the spirit cooking shit and all. There're secret government agencies filled with serial killers, except they recruited from foreign countries and their job is to be think tank to figure out how to cover up murders using their experience. They then communicate those methods to other departments.
