Your arguments are invalid. If you take a look at all the wars that are well known...surely you'll notice that they are not well known because of the fact that they were caused by religious beliefs. The American Revolutionary War, American Civil War, English Civil War, French Reign of Terror, WWI, WWII, Cold War, the various Civil Wars that have happened throughout Africa, Rwandan Genocide, American War in the Middle East, the War between Kenya and Somalia...really I could go on.
