I guess %95 of Muslims are offended by this. In their beliefs you can't paint a picture of Hz. Muhammed. You can't make jokes, make fun of him, write comics etc.
OK.. they can ban this book in regions where they constitute a majority, such as Brussels and London. That said, I have seen Muslims making fun of other religions. One of the best examples is Zakir Naik, who frequently mock Hindus, Sikhs and Buddhists. He is apparently considered by the Indian Muslims as an "authority" in Salafi ideology.
