There are a number of posters at BFF and Cryptomundo (those were the sites I used to check) who every now and then try to defend creationism and defend the position that the current existence of animals considered to be exctinct supports their beliefs. I suspect much of the "anti-mainstream science" drivel from many a poster comes from this source- religious fundamentalism. Some posters's writings clearly expose their fundamentalist and intolerant views. As soon as the debate pops out, here comes mod intervention -there, not here. I must add that I don't think its a small part of the footer community.
That's something we're going through in this country. Check YouTube. You'll find comments are disabled on the Kent Hovind vids, but there's a lively debate going on on Ken Miller's talk at Case Western where we get inundated with copy and pastes from Answers in Genesis. Bigfoot is not a topic there.
The Religious Right is a loud minority in the US. It's something school boards are having to deal with, and go to court over.
I got into BFF through Creationism vs. Evolution debates on AOL message boards. Creationists were invading every fossil-related topic, reporting evolutionists and sending Burn-in-Hell-Sinner e-mails to us all.
Out of all the posters who responded on the MABRC EvC thread, one had read Darwin's Black Box and thought there was something to it, most accepted evolution but styled themselves Christians, one mentioned a "higher power", two were fundamentalists, one was a YECer and two were atheists. I wanted to keep it going partly so I could get an idea of whose critical thinking skills might be greatly impaired.
I'm not into the other things you mentioned, but you know that.
The exact comment that got me checking out sasquatch on the Net was a quote of Michael Schermer's on "people who believe in bigfoot also believe in UFO's and the Loch Ness Monster". It was off to the races after that.
It's an unfair characterization, IMO. We're a mixed bag. There's a lot of social pressure to conform, and you might find southern researchers are more prone to go to church Wednesday nights than those in the North, but I wouldn't want to assume that without a proper study.
