Now here is what Islam needs to learn that most of Christianity has, you can find something offensive and speak out about it without going on killing sprees.
Christians got upset over the photo "piss Christ", missing the point of the artist who was not anti Christian, but pointing out the hypocrisy of many in Christianity. Even as offensive as they found it, most of Christianity in response to it protested in a civil manor.
Atheists when you blast us, cuss us out, or depict us in a bad light, the worst you get from us is a "fuck you".
Religion, all religions, need to grow up and learn that if the worst you get is picked on, you are doing good. There are minorities in the world of all labels that have to fear retribution and arrest and death. Being picked on or cussed out or blasphemed is nothing compared to living under fear of death.
