Oh boy... Between living with the hippie vegan urban "survivalists" ("off the grid") and the bible humping militia type survivalists (also, "off the grid") in the deep desert, I've heard 'em all. I don't even know where to begin. I will say, however, that between these two populations, they share almost all the same ideologies/world views, and their conspiracies overlap significantly (they also lack access to or otherwise refuse mental health care, or health care generally, and are entirely undereducated). Everything from Obama being a hologram, to a crippling fear of "government workers" (always undefined boogie men, sometimes in invisibility cloaks sneaking about the house hiding things, to black op spooks i.e. me asking too many questions), everything that happens is a covert government op or government conspiracy or sleight of hand to distract.
A childhood friend, total tin foil hat pot smoking anarcho-lefty hippie type, believed microwave ovens caused all illnesses. He would turn paper white when walking into someone else's kitchen. He claimed he stopped drinking water, insisting he only obtained moisture from his food (fruits I guess, as we're dealing with a raw food vegan here), and drank only his own urine or juice (because nature is the best filter for his fluids AND he claimed his body, after decades of vegan tuning, has become a super pure juice machine. Potable water, from the tap, of course, contained mind control substances. He had a big phobia over fluoride). He also does home surgery on himself and composts his and his family's feces (in an extremely improper unhygienic manner). He has a beehive in his back room that he hasn't the heart to disturb on account of the insects' welfare (don't get me started on the 10,000s or palmetto bugs everywhere day or night, and the lice and the bed bugs). Generally, his household is a public health problem and nuisance to the surrounding community. It's actually quite sad now that I think about it.
An ultra conservative wingnut I once worked for believed that there is an ocean portal somewhere in the north Atlantic allowing access to the hollow earth where the benevolent hyper intelligent giants dwell. Well, the hippie also believed this too. The things specific to the winger nut revolved mostly around the accumulation of firearms. Lots of crazy with that guy and his buddies.
Dimension hopping Sasquatch, the order of the E.T.s; greys and greens and reptilians, crop circles, chemtrails, mind control radio waves, telepathy, demonic agency, ghosts, trutherism, mysticism, ancient astronauts, anti-vax, anti-medicine. anti-establishment EVERYTHING. Typical C2C fare.
I'm really going to have go back into the way back machine to find the craziest madness I've come across...
