Some people are so amazingly stupid it's a wonder how they're able to function.
The "chemtrail" conspiracy theory (incorrectly) states that the condensation trails (contrails) left behind by high-flying airplanes are really chemicals sprayed by government aircraft to control/poison/do whatever to the population. It's so ridiculous that I'm getting tired of explaining it to people.
Contrails are cirrus clouds created by the warm, moist jet exhaust of high-flying aircraft meeting the extremely cold air in the upper atmosphere. There is no such thing as a "chemtrail," but the wackadoodles who believe in them won't take no for an answer.
The chemtrail conspiracy theorists are to the point where they're harassing and threatening meteorologists and their families for daring to take them on with science. And, apparently, at least one of them wants to aim laser beams at the cockpits of aircraft.
It is a federal crime to aim a laser beam at an aircraft, punishable with up to five years in prison, and they'll charge your dumb ass with terrorism if you make it crash.
If chemtrail believers spent as much energy studying real science as they did propagating conspiracy theories online, their lives might not suck so much that they think there are people out to get them.
