Solea, do we know the same people?
kidding, this stuff is rampant.
The Chemtrails thing has reached almost mass hysteria.
I remember being a kid, under 10, and lying in the grass watching the contrails from planes. Even as a kid I could figure out they were water vapor from the hot-engines, and could trigger cloud formations, etc. Its like when you blow hot air out of your mouth on a cold day...a Chemtrail from your mouth! (I know they say all contrails, are not chemtrails...the conpiracy is all worked out in detail, even the coverups).
But people now get bad info from the internets, and they flip into the paranoid conspiracy channel.(If they had a Paranoid Conspiracy TV channel, it would probably get great ratings).
Then that gets combined with End Times, Illuminati, and the rest of it. There are zillions of people who believe the Illuminati thing, basically the DaVinci Code stuff. [skepdic.com
It seems everyone believes a little bit of "crazy" stuff, and that is not too damaging.
Its when people get fed an entire bogus worldview from the new age cultish groups, and then get led down the garden path, then that is real trouble.
There is a good book, Why People Believe Weird Things by Michael Shermer.
But all I can say, is people don't seem to change these types of beliefs based on evidence, they try to make anything they can find fit the belief they want to have.
But sometimes people change, after many years, and maybe once they take it too far and hit bottom with it.
Maybe its like an alcoholic drinking booze...
