Not to impugn your or your friend Charlie's knowledge but a quick Google search gave me a bunch of links that suggest the "witches" burned where nothing of the sort. That's like saying that only the mentally ill were put into Nazi concentration camps. Sure they were but that wasn't the largest group. Saying that witches were burned (which is inaccurate anyway because what do you mean by witches? Wiccans who didn't exist yet? Pagans? Nature worshippers? Satanists?) presumes that people were sophisticated enough to differentiate between a real witch and just the guy down the street who owes you money. It's not realistic. Most of the people were probably just like the rest of Europe at the time, Christian of some flavor or another.

Court records go back plenty further than the printing press. They're just hand-written is all.

Wasn't Britain colonised by the Romans? Who weren't Christian and generally fonder of not giving a damn about religions that didn't rouse-rabble?

Oooh, except that I see this one site is blaming the Burning Times on the Inquisition. Yeah, that's about as inaccurate as you can get.
