It's a fair cop.

I would so like to leave it there, but in case anyone doesn't get it, it's a quote from 'Monty Python and the Holy Grail'.

And what I mean by it is: It's not a bad idea, if you believe that the world is ruled by good and evil powers, that some people might serve evil.

The problem is that it doesn't help you find the evil-servers.

You need a witch-test.

And you need to check very carefully that it works! Or you will do immense harm. (I am looking at you, TSH)

We didn't stop torturing and burning witches because we suddenly became kind. If Satan, and witches, existed, then they would deserve every bit of it. (Obviously I speak of the mediaeval conception of witches, not the modern pagans, who are awfully nice people who care about trees and knitting)

We stopped torturing people when we realised that you can get anyone to confess to anything by torture. (I believe that experiments were conducted.)

And now, we don't believe in the Evil One, so we don't even think witches exist. (Leaving the Wicca people to play their beautiful harmless games which everyone approves of)
