First off, no there aren't any songs in the Harry Potter film, and I can't really see any of the verse in the books being fitted for singing either. The score in the film is about the only thing I have any reservations about. It's the Star Trek John Williams, and it's a bit overblown for my liking. I think the other John Williams who plays the guitar cold probably have done a better job on it.

As for the question of whether there's any good in talking about this kind of thing, I think there can be. The danger of this type of fundamentalism is that it involves hijacking a religion, in the same way fundamentalism of the Bin Laden variety does.

So on the one hand you can get people who think that being a Christian means thinking like that, and they decide that since they are Christians they should go along with it. Or they recognise it as pretty detestable, and they see that as a reason to denounce Christianity.

In fact the same would apply if we were talking about an analogous kind of Islamic fundamentalism, or Jewish, or Hindu fundamentalism - I imagine they'd all share a common attitude towards Harry Potter.

The effect of this kind of thing is to lead people to equate bigotry with religious belief and practice - a view which is in itself a form of bigotry.

And one of the consequences of this is the backlash effect which is demonstrated in the ludicrous and distasteful concept of a demythologised version of the Narnia books.

And another could well be that the way is opened for Harry Potter to become for some people a way into types of occultism that can cause real damage.
