I have an issue with those that say this is nothing to do with Islam. Clearly it's nothing to do with the peaceful section of the Muslim community, who make up the vast majority. Jidhad, holy war is a belief that is part of that religion, as is the evangelical ideal held by some that their faith alone should prevail and we should live under a caliphate.
We went through all this with Christianity five hundred or so years ago, and incidentally I have never seen it written by anyone on GN that the persecutions inflicted under the Spanish Inquisition, or recent abuses by the clergy were nothing to do with the Catholic church, clearly they were as indeed the numerous atrocities that are happening in Middle East are something to do with Islam.
Religions evolve because they are predominantly man made and those men want to drive it along for their own ends, usually to control other sections of society, infidels and of course WOMEN, sometimes religion morph into something dark and very evil.
