Brilliant post, noise
I agree with your blunt statement. Something which is impossible to not notice on musicbanter is that whenever there's talk of conspiracies or UFOs and the like, there are some usernames that come up as supporters. There are some people who I get the impression are less critical and more likely to swallow wild UFO claims whole. Their approach to this sort of "stuff" - whether it's Obama's plans for putting americans in concentration camps because he's the antichrist or that corn circles are being made by visiting aliens - with a sort of general approval and acceptance. Since various wild claims and theories are being supported by the same people over and over, it leads me to think there's something about the people who believe in them rather than the claims themselves.
If I were to put it blunt, I would just say these people are idiots.
