Everybody's Paranoid About Something

There are plenty of conspiracy theories to choose from: 9-11, Kennedy Assassination, UFO's, the Masons, the Illuminati, Skull and Bones, New World Order, that Reagan's shooter was a Bush family friend, that AIDS was manufactured, that the levees in New Orleans were blown up, that the Waco fire was set by ATF, there are enough to go around. This conspiracy site is actually very interesting reading and according to Wikipedia:

A number of true or possibly true conspiracies are cited in making this case (for conspiracies); the Mafia, the Business Plot to overthrow Franklin Delano Roosevelt in 1933, the MKULTRA mind control program, various CIA involvements in overseas coups d'état, Operation Northwoods, the 1991 US Congress Testimony of Nayirah (that babies were being thrown out of incubators in Kuwait), the Tuskegee Study of Untreated Syphilis in the Negro Male, the General Motors streetcar conspiracy, the plot by the British Secret Service to destabilize Prime Minister Harold Wilson and the Pearl Harbor advance-knowledge debate, among others.

The only paranoia that is seen as commendable is that you are under constant surveillance by a God. In some states, this belief is even required to run for office. Many people make millions of dollars out of promoting this delusional thinking unlike most conspiracies which might generate a book but not THE BOOK.
