In an age where I can carry the complete works of William Shakespeare on a device small enough to fit in my pocket, book burning is primitive and irrelevant. I can download and delete the Qur'an over and over, all day long. It means nothing. And in the end, all books will succumb to the rot of time, crumbling to dust, without the help of a zealot's flame. There are no sacred objects.
That we are even having this debate shows how far we have fallen. We are now appeasing the barbarians who have always intended to slaughter us all, anyway.
Let it burn.
