Snopes is an urban legend site: it's only presenting those points that back up the urban legend at hand -- that being that the story is "anti-religious". It's never been intended to be scholarly resource or even a serious reference. There is very little context... and I'm sorry, but those emails at the beginning are total crap (both boycott spam mails). They're relevant as the sources of the "urban myth" but to repost them out of context of the rest of the site would seem to give them credence in and of themselves.
As for the bibliography: none of the resources cited seem to actually have been quoted (or even read... one isn't even about the series, it's about the Chronicles of Narnia).
The entire issue's been summed up in 2 and half paragraphs. Half of the article is information is easily obtained from wikipedia -- the other half is taken directly from the Catholic League's anti-film presskit (Which isn't mentioned in the bibliography). So much for sparkling research.
The Actual Resources:
-FOX News Network (can't find it)
-Peter Hitchens (op/ed column by British conservative politician, extremely negative, Philip Pullman by Peter Hitchens)
-The Times (this is a decent enough one ~ Pullman writes a book that will shed light on darkness of his beliefs - Times Online)
- The Guardian (this article is actually a story about "The Chronicles of Narnia", only the title comes from the Pullman books... His dark materials | By genre | Guardian Unlimited Books)
-The Shed Where God Died (and absolutely EXCELLENT article and good overview of the issues at hand - The shed where God died - www.smh.com.au)
-http://www.newyorker.com/archive/2005/12/26/051226fa_fact (very long... biographical of Pullman)
Paulie Michelle (just a biography of pullman and information about his awards, irrelevant to the issue at hand)
(Can't find this one...)
(can't find this one either... but I can find about 800 similarly titled stories reacting to the film boycott and the church uproar)
