"Must a Bigfoot-type creature seen with a UFO or other high strangeness be called something other than Bigfoot? Many researchers would say yes. Why?They often have quasi-logical explanations for saying creatures spotted with UFOs aren't Bigfoot, even though the beasties look like Bigfoot. But the real explanation lies in the underbelly of Bigfoot research-the researchers' feelings. Too often emotion becomes entangled with the investigation, as the researcher struggles to justify throwing out sightings that disturb him. High strangeness associated with Bigfoot clearly disturbs a lot of people. Therefore, researchers attempt to separate the so-called flesh-and-blood Bigfoot from the so-called paranormal Bigfoot. But there's a problem.Bigfoot is paranormal, no matter how you view it."
