Truthers definitely are the worst. I like that old time Masonic/Illuminati mind control stuf, but in the eighteen or so years that I've been reading that kind of stuff, not much has ever stuck with me, though maybe that's PART OF THEIR PLOY!
I guess I like the idea of that kind of stuff a lot more than the actual material.
I'm more into collecting xeroxed flyers/wall posters/communiques that schizophrenic people post around town than any sort of "official" conspiracy theories, but it tends to be more just whacky Christianity than conspiracy per se. I just got some crazy booklets by a christian on welfare who was mad that his friend wouldn't lend him any "dead trees" to get his haircut, and how his barber was really mad that he had to wait until the end of the month. Apparently, "between tomorrow she would not be "spending them" (i.e. USING THEM TO TAKE OPTIMISTIC ADVANTAGE OF OTHERS SLAVERY) in the meantime anyway!"
Mostly just a lot of ranting about "dead trees sitting in their banks", which he also calls "wooden devils taken out of a GD GREED MACHINE" (there are atms here called TD Green Machines) mixed with biblical verse and horribly drawn pictures of who i can only assume is jesus. Four stapled booklets that are mostly repetitive, but feature different aspects of how money is ruining his life.
