Christians and Harry Potter

I am a bit taken aback by the scorn that S.M. Hutchens and, to a lesser extent, John Granger direct at Christians who do not share their enthusiasm for the Harry Potter series. My problem with the series is not the imperfection of the characters or a failure to appreciate the great works of western civilization. My problem is that the books are about magic, a practice that the Bible always describes as demonic. It is surprising to me that neither Mr. Hutchens nor Mr. Granger address this objection. The Ephesians burned their magic books after their conversion to Christ. Would they encourage us to read books that celebrate magic? Moses told the people of Israel that the penalty for sorcery is death. Would he encourage us to let our children read books that celebrate sorcery? Would Paul, after rebuking Elymas and striking him blind, rebuke Christians for having a problem with books that celebrate the practices of Elymas? I do not mean these to be rhetorical questions. Perhaps the answer is a resounding yes, but I would like to hear Mr. Hutchens and Mr. Granger explain why. I would also ask them, if they wish to persuade us naysayers, to "gently teach those who oppose the truth," as Paul recommends, if we are in fact the ones who are opposing the truth.
