Ok, we are not at war with Islam, but it just happens that Islam is at war with us.
Not from now, but since fourteen centuries. Here again it would suffice some knowledge of history. First half of the Byzantine empire was lost to the conquering onslaught of the Arabs; centuries later the remaining part of the empire collapsed under the Turkish pressure; still in the eighteenth century the Turks were besieging Vienna. Do I need to continue?
Does this authorize us to want to burn the Qur'an. Well, no. Why to provoke in vain? But that is not the question. What I ask is whether we can criticize the Qur'an. Here is at stake one of the basic tenets of our civilization. And I am afraid that the answer come close to a blunt no!
Burning the Qur'an would be a drastic show of criticism. But even milder signs of it arise angry masses in the Muslim world. Think of what happened after the Pope's Regensburg address.
Spontaneous uprisings? Allow me to doubt it strongly. I don't think that the average Pakistani or Indian Muslim attacking Christian churches follow the western press, or television or internet. But there is a planned war run by way of the media, to provoke terror and psychological subjugation. So Europe to a large extent, and to a lesser extent the USA, already live in a state of semi dhimmitude, because of the fear to speak out.
The trouble is that while here we are concerned with not rubbing Muslims the wrong way (if we don't want to endanger our or other Christians' lives), Christian lives are considered expendable in large parts of the Muslim world. Any non Muslim life is considered expendable.
Ok, this is the best I can do for now.
