It certainly seems to be the case to me that Bigfoot enthusiasts have taken any Native American (or indeed, any worldwide aboriginal) legend of a bipedal figure that lives or lurks in the woods, even if the figure is explicitly described as just a man, or some type of spirit or ghost rather than a physical creature, and unilaterally declared that every one must be a reference to Bigfoot.
Without exception, so far as I've seen, beyond whether the character lives in the woods or is described as "wild" and/or hairy, Bigfooters are altogether uninterested in the specific lore of these disparate cultural figures. Is it kind and helpful to humans, or does it hunt and eat them if they stray too far from the village at night? Was it sent by the gods to torment humans, or was it a specific, otherwise-normal person who was banished from civilization for some transgression and is now condemned to live as a "wild man"? None of this is important or even relevant; it's obviously all just silly stories the ignorant natives have made up to explain the animal's presence. All that matters is that the legend exists, which proves the creature is real and is definitely the selfsame creature that all of the other vastly different cultural legends around the world are referring to: namely, the Pacific-Northwest Bigfoot/Sasquatch as conceived of by American Bigfoot enthusiasts.
