In general I tend to dismiss them on the grounds that I have never come across any organisation that efficient. The military? the term snafu comes to mind. The CIA, FBI, MI5/6, NASA, the royal family, you name it bud, they all fuck up. Corporations and businesses who make money out of getting things right can.`t be trusted. Airlines lose your luggage or over book. Your mechanic gets sent the wrong part. The list goes on. Even the catholic church which sociologically speaking should be the most efficient organization going, (it being a meritocracy) is a crumbling mess.
Are all these theories a substitute for a belief in god? Having rejected and despising conventional judo-christianity and leaving a healthy distrust of establishment organizations. The young in particular, seem to crave a belief in the preposterous. Homeopathy, reiki massage, paganism and conspiracy theories.
So what (if any) conspiracy theories do you adhere to?
