Please stop talking to me in a way that implies I would be religious, or even sympathizing with religious fanatics. I have been an atheist my whole life, just as the rest of my family. The way you talk makes it sound like if I would be religious and that is offensive to me. I´m not in any way siding with the idiots who attacked the embassy, this is much more complex than choosing sides. I naturally condemn all aggressive and all violent actions on both sides. However -I was trying to make a point about sacrilege- so back on topic:

Think about it. Every civilized country has laws against offending people, so obviously there is a global consensus that the law should aim to protect people from being offended. You probably agree that what is considered offensive depends on the cultural background of an individual and is different from country to country. Now consider that to followers of a religion a desecration of the symbols of their religion** is the worst possible offense that is thinkable**. Why do you argue that certain (religious) people should be excluded from the protection by law against being offended - just because they were born into a different culture than you were and thus believe other things than you?

Burning sacred books of a foreign religion is a sign of intolerance and a poster-like act of aggression, offense and provocation that aims to cause an outrage in the targeted religious community. This fact can not be ignored when assessing events of this kind. It also does not excuse violent behavior by the offended community in my opinion but that is another topic.
