I think you're really giving them too much credit for being in on it all. I mean christians and hindus really do believe in their crazy stories (at least to some extent).
Looking around BFF you find people that are arguing that the US government is covering up bigfoot because of the profit the govt. stands to make from doing so. And other people eat it up. Other people trying to link bigfoot and Mothman as maybe being the same thing or similar.
I'd find your point more convincing if these people were establishing like fully fleshed out and cogent fictions; short stories about crazy woods monsters. Instead, it's more like a bunch of random ideas and random speculations.
Really, the only thing that puts me kind of in your "they all know" camp is that none of them really fight over details so much. (That I have seen). I don't see any evidence that they are over there trying to piece together all the available information on a living creature and sort out the wheat from the chaff. It's a bunch of wildly different and frequently contradictory "facts" that no one seems to interested in trying to make sense of except when a skeptic speaks up.
I didn't specify a definite
all. But, maybe pretty much all. Wasn't really considering the deranged in the assessment, anyway. But no matter how wacky some may seem, I think they come to know. The whole govt/NSA/MIB type thing I see as simply more stories to enhance the original story. The trouble with Bigfoot is that it is actually
less believeable than other crazy stuff. Chupacabras? Elusive alien hybrid CIA experiment. They probably dissolve, or something... Little grey men? They're aliens. Who knows what they do... Ghosts? Well, they're ghosts... And so on. Chalk it up to magic, or something. But, Bigfoot is this real, undocumented, 8 foot 500 pound behemoth, that is
everywhere. He's in your dumpster, your trailer park, your backyard. Yet, Biggie just won't show up when you need him. Biggie is like some deadbeat friend. Ironically, I think that those who adhere to
magic Bigfoot, interdimensional, time travelling sasquatch, are possibly not engaged in active deception. Historian wasn't a liar. He was simply crazy.
These Footers (in general) know it's all crap. Bigfoot can't be everywhere the reports and stories say he is and have nothing to show for it. Footers know that the reports are lies. When you rule out 90% as lies and 10%
might be lies, they understand it's a big joke based on telling whoppers. They embrace it, or go rogue. I doubt that most with their own stories of encounters think they really saw Bigfoot. I doubt that they even think it
might be Bigfoot. They know it was never Bigfoot. It's all role playing and yarn spinning.
If the original prank had stayed this super-rare, elusive wood ape in a tiny area, then maybe I could believe that they're just gullible, or hopeful. But, it's not like that. It got out of control rather quickly and now Bigfoot is in the everglades, opening pork and beans with a screwdriver, eating garlic in Tennessee, in back yards in New York and whatnot. It's a club of hucksters and tall story artists. Some are in it to grift, some for the pranking, some to simply socialise with other fibbers.
Not trying to tell you that this is fact. It's just my opinion. I reckon that they're not, as a whole, a bunch of simple feebs. They're just liars.
