The problem with this debate is that both of you are incorrect in your assertions, but also ironically incorrect in your criticism of each other. History is complicated, and so, no, Islam is not a religion of violence, but no, it's not a religion of peace, either. Same with Christianity. Religions are complex social structures that reflect underlying cultural forces, both good and bad.
Take Iberia. The classic understanding is that it was conquered by the Muslims, who were stopped at the Battle of Tours, and then slowly reconquered by Christians until the last Muslims were defeated at Granada. That's 750 years of religious strife. Obviously it's not as simple as that, because if it were, there would be no people in Spain, because they all would have died a long time ago. Instead, the history is more complex. Yes, Muslim leaders conquered Christian cities, and Christian leaders conquered Muslim cities. Yes, some of those cities were depopulated (sometimes by force, but often just by people trying to avoid war). But for the most part, during those 750 years, Christians, Muslims, and Jews lived together in relative peace. They shared pursuits both academic and economic. They intermarried. Swore fealty to each other. When Muslim rulers were ascendant, Christians paid a special tax to them. When Christians became dominant, the local Muslim rulers became their vassals and paid them instead.
Iberia is just an example, but this pattern holds true for all of Europe and the Middle East. Some times were more violent than others, but for the most part, people were just trying to get by, and they lived and worked together when they could. The common perception of Muslims conquering the world and converting the masses at swordpoint is largely imaginary, just as the perception of the Crusaders as hellbent on exterminating Muslims in the Holy Land is also largely imaginary. Largely because those unflattering portraits are based on kernels of truth, but imaginary because those kernels honestly don't accurately tell the broader story.
Crazy is wrong to act like the Muslims were especially bad. They weren't. They were just acting like any other medieval society. But Jimbo is wrong to act like organized religion is the disease behind all this violence. It's not. Genghis Khan had one of the most cosmopolitan courts of the time, purposefully recruiting people of all ethnicities and cultures. It was a truly egalitarian government. And yet he killed more Muslims than all the Crusades combined, and if he doesn't have the record as the #1 Christian killer, it's only because he died while the Mongols were just barely starting to tease Europe.
Finally, none of this has much bearing on today. Today is largely about political and ethnic disagreements between two groups of people who both want to occupy the same land, and the places where religion enters into it are largely modern - Wahhabism didn't arise until the 18th century, and the most radically religious versions of Zionism are even newer than that.
That might be a bit overbroad and rambling, but I think it's enough for now. I'll be happy to go into more detail in any areas you have disagreements with.
