Le Temps des bûchers
A film rather than a website: a history of "The Burning Times". It's reviewed at http://www.nfb.ca/FMT/E/MSN/19/19994.html.

WITCHCRAFT, SATANISM, AND THE NEW AGE (http://www.balaams-ass.com/journal/warnings/witchcrf.htm)
OK, just for laughs - that is, if you're not too creeped-out by it - check out this Christian site. It's full of anti-pagan rants (also anti-gay, etc.). The authors see signs of a "New Age" movement everywhere they look. Of course they condemn all of it as "evil" because it disagrees with The Bible. And not only that; they even associate "New Age" with all that hoary conspiracy- theory stuff. Bizarre. [Just a sign of how extreme this site is, they recently had to remove some content because of the Hate Crimes Bill!]
