i think worse than conspiracy theorists, are people whose instant reaction when presented with one is "ohhh...preposterous, don't be ridiculous, weirdos, humph, bluster..."etc, and feel this is a conclusive argument.
as though the simple fact that it is a "theory of a conspiracy" instantly makes it utter garbage.
not all conspracy theorists are underground loonies living in a basement mini fortress filled with newspaper cuttings and computers analyzing data....some are just ordinary people who don't trust the government....
people not trusting the government 'eh? imagine that!
conspiracies do happen, and to assume that every action of the powers that be is above board, honest, for the good of the people and couldn't not possibly be called into question is somewhat naive.
I have found these people have usually done very little research because their minds are already made up.
