You're grouping people with the perpetrators of crimes and painting everyone broadly as a criminal, that doesn't make Christianity a Religion of War, nor does it demonstrate ANYTHING about any religion being the problem for WAR.
Throughout centuries of history of these religions, you will find inclination for intolerance, violence, and war. All three condone war in the name of their religion, all three have had wars in conquest of their religions, all three have killed in the name of their religion.
All 3, except you're speaking upon groups of people and making huge generalizations without any context, I expect you can demonstrate each and every one of the assertions, least demonstrate that the Religion itself is Inherently FOR war and not peace, and you seem to take us "back in history", is that recent history even, and what about the numerous massacres and genocides that were promoted by Conquest, Might equates Right? It was because the Church blessed the conquest that makes it the issue of religion?
All the people who go to war wear shirts, therefore shirts are the cause of all wars.
You can go all the back to the crusades and follow it up through the times. If you really want to find out the heart of all the hatred in the middle east just takes some time and look at all the different groups willing to kill each other over religion. I was a moderator on a middle east blog site and I sat down and tried to honestly figure it all out, it just can't be done, it's heartbreaking and depressing because it can be the most minute difference that makes or breaks it for most of them. It would be no different for example then if Christians attacked Catholics, or Mormons attack Baptist on a daily basis in this country. In the middle east they have no problem with genocide based on religion.
