I found this a few years ago, I don't remember if it was by purpose or by accident but it came at a time when I was personally conflicted with my faith and the celebration of Hallowe'en. I was indoctrinated in Chick tracts (look it up if you want, they're basically 'if you don't believe the way I do because I am a comic book artist [only fair artist] and if you don't you're going to Hell' sort of things), fear tactics from my church and loads of well meaning but WRONG (and a lot of downright blatant LIES) information on everything from Sam Hain who is the great god of death that the Celts sacrificed babies to, to jack o' lanterns were representative of damned souls, to witches are devil worshippers.
This straightened all that out and I agree with Ms.Rowan Moonstone, a Wiccan, from the the article, "I have no problems to Christians being theologically opposed to Samhain. What I absolutely refuse to tolerate is sloppy and improper scholarship!" I wholeheartedly agree.
