For a long time, most American proponents of the existence of flesh-and-blood Bigfoot, would not entertain for a moment, any suggestion of paranormal involvement: the mere implication of it got them spitting angry -- "it's a lazy way of thinking !" -- "It's ridiculous to try to explain one unknown in terms of another unknown !" My impression from that scene in the past couple of years, though -- with, ever and anon, nothing brought to light, and a good deal of blatant fraud and fakery having been uncovered -- is that outside of the small core of "frothing fanatics", many folk involved in this stuff have been broadening the scope of what they reckon might be going on.
