I'm not using Christianity as a scapegoat at all, I'm a baptised Christian myself. Sure the pope didn't travel with the army but he did call for the crusade in the first place with the intention of conquering Muslim territories. You don't have to be leading an army to be a conqueror. He was the original reason these armies existed and why they travelled so far to fight the Muslims in the name of God. Christianity is one of the most violent religions in the world and even if Islam has slightly higher numbers of deaths as a result that doesn't make it not so. I could find a huge list of atrocities committed with Christianity used as a perceived excuse.
I'm not contesting that Islam has a violent past, just that they were no more violent than the world that they lived in and the other groups of people that surrounded them, such as the Christians. If you label Islam a religion of violence then you should label Christianity one too. You even admitted that you have met many peaceful Muslims so surely it is an insult to them to label them as violent simply because there are other Muslims who commit atrocities. That proves that Islam is capable of peacefully coinciding with society just as Christianity is. We have an issue in the modern world with radical Islamic extremism not Islam.
And Karth many people view Islam as a religion solely for violence as a result of past atrocities so surely it is only fair to bring up the things that other religions have done, such as the Crusades. You're just proving what I'm saying, it's not Islam but Islamic extremism that is the issue. Islamic followers can be peaceful. We need to help them combat views of extremism within their societies rather than label them all violent when that is clearly not true.
