William--- I see... I missed the meaning of the "that they believe" part. I've never thought of that angle before. Let me think about it...
OKAY GOT IT! HERE ARE THE SEVEN TYPES OF BELIEVER:
1) The Biscardi-esque style belief - That would mean someone who in the tradition of Wallace and Marx really don't think Bigfoot is real, but love to manipulate people with hoaxes and become leaders in the field. If possible, money-making films or expeditions will ensue.
2) The Pattersonite belief - That's someone who, in Al DeAtley's words, would "Lie, cheat, steal or hoax to prove it to you". He thinks there is a Bigfoot and wants to be the hero to find it, but till then he's happy to do what it takes to earn fame and fortune by faking it.
3) The MelKrantz-ist - He thinks he's open-minded to the idea and can accept any scientific analysis that proves true either way. He then will go out of his way to bend the universe to prove he's right in his theories - even if his belief turns out to be a hoax with a confession to back it up. Why? Because he's too smart for the less intelligent hoaxers to fool.
4) The Patty is real club - That means our group has decided and we have painted ourselves into a corner. Anyone who points this out must be dealt with and eliminated. Patty (and thus Bigfoot) must be protected from non-believers. They've spent decades on this and cannot look past the faith.
5) The I saw a Bigfoot guy - He looked Bigfoot in the eye and lived. He knows what he knows.
6) The Bigfoot seems to be possible Passerby - Based on legends and previous finds of unknown animals and people, they feel 50/50 on the subject. Could be, could be.
7) Para-Bigfoot is supernaturalizer - He sees all sorts of things and makes Britney seem level headed.
Those are the basics. These are the folks you will meet on your journey into the maze that is Bigfoot. I'm number 6. Hello.
Now... it's UP TO YOU TO PROVE Bigfoot doesn't exist. (*Anyone who speaks that phrase to you has just PROVEN he's a real believer)
