People burn these books or scrolls etc for a reaction and the Muslim community give a reaction they are looking for (outrage, anger and violence in many cases). Just don't react. Ignor it. The novelty will ware off. The impact will lose its clout and effect and die off, that's how you gain the upper hand and win. Islam is bigger than a physical burning of a book, the words are not diminished in anyway if a human printed version is burned. Produce another. Being insulted can be contained to a statement rather than violence or anger.
