First, thank you for a non-hysterical reply. Now, to address your arguments...
I don't know how many Potter readers are converting to white or black magic. I don't think anyone does. All we can do is take an educated guess. From the testimony of the authorities that I trust, and that I've actually read (the chief exorcist of the Vatican and the exorcist for the archdiocese of NY), I believe that the danger is real.
Moreover, we have the testimony of the head of England's largest pagan organization, who claims that enquiries to his group from children requesting information regarding witchcraft has increased significantly since the advent of the Potter phenomenon.
Next, there is no doubt that Ouji Boards etc. open the doors to the demonic realm. I had HS classmates who had some incredible and unexplainable things happen to them after using a ouji board.
Pay attention scoffers.
But Harry Potter is not the equivalent of actually trying to initiate contact into the other realm. Reading a fantasy book does not do this.
True. Few children probably pick up the book with this intention.
It is only if they act on what they read and start reading spell books, the Book of Shadows, etc., that the door to the evil one is truly opened.
And that is precisely my concern. Children copy what they see. What parent can argue that? And one can safely assume that children who become interested in witchcraft are very likely to attempt spell-casting and other occult activities that are modelled in the books.
Most kids are able to see Harry Potter is fiction, not reality.
True. But it's the minority that I'm concerned about. And how can we know which children will become interested in the occult after reading the Potter books before the fact?
