The JREF (James Randi Educational Forum) has a new thread on Bigfoot; this one is titled "Mormon Bigfoot Genesis Theory." I stopped counting long ago how many Bigfoot threads there are on the JREF but at last estimation, it was around sixty. Sixty seperate threads on a "skeptic" site about a creature the majority of posters don't believe exists.
Interesting thread, on the Mormon folklore about Sasquatch. And, about UFOs. Not connected, according to the OP, and I'm not that familiar with Mormon doctrine. But it is an interesting juxtaposition.
Naturally, the skeptoids scoff at this; because it's Bigfoot, because it's religion. (The only valid point made by the OP is the potential racism inherent in this folklore -- kind of like David Icke's and other Illuminati loving theorists, who disguise their anti-Semitism with code phrases like reptilians, world bankers, etc.)
But in reading about Mormon founder Joseph Smith's experiences, it's clear he had contact with something that is very close to alien/UFO encounters. And in reading the book of Mormon, with different tribes stealing chests full of DNA, -- it reads like a sci fi novel. Parallels are clear, as Biblical/religious text UFO researchers know.
