To a Muslim it is offensive to say Jesus is God. It is offensive to view images of inappropriately clothed people. Muslims in Indonesia found the images in Playboy sufficiently offensive to riot over. Muslims in Malaysia frown on the usage of Muslim terminology in a non-Muslim context; the government has actually banned Malay-language Christian publications for using Malay words meaning "Allah", "angel", etc. There are a lot of things people find offensive; there are a lot of things Muslims find offensive.
I think you need to remember that not all Muslims are from the Taliban, just as not all Christians are cross-burning Ku Klux Klansmen. I studied in a Catholic school where several of our teachers were Muslim and knew more about the Gospel (and modern physics) than the average church-goer. I've known several Muslim girls who frequent night clubs (not dressed in burqas incidentally) and don't mind listening to remixes of Sufi hymns. Just because some Muslims "run riot" over alleged insults to their faith doesn't mean you can generalise against the entire Muslim community.
Moreover Saudi Arabia is an individual country whose laws do not necessarily reflect on the global Islamic diaspora. Just because Holland permits prostitution doesn't mean I can say that the entire "Christian West" condones the flesh trade. Indeed implying that Muslim = Saudi Arabian = Malaysian Muslim = Pakistani Muslim = Indian Muslim would be offensive to Muslims who value their national identity over their religious one - and I assure you there are several of them.
I feel that the Muslim community is being referred to very condescendingly in this thread and we must remember that a majority of Muslims are educated, moderate, cosmopolitan and far removed from the Fox News stereotype of unshaven fanatics with Kalashnikovs who will turn up at Wikipedia's head office with RDX and a copy of the Qu'ran. Indeed they have no more love for violence than the average American college student who decides to gun down his classmates.
