I am watching Kingdom of Heaven, a movie about the crusades. It is an entertaining flick and there are some interesting things you can take from it. One point I think that they try to make is that Christians and Muslims are not too unalike in using their religion to justify killing those of a different faith. Many scenes and dialogue show the very real attitude of the day that God wills the killing of Muslims and that somehow it can cleanse your sins. The Muslims of the day also believed the same. The one big difference is that we (Christians) don't believe or practice that, the Muslims do.
Is it because Christians are from the west and our culture is superior? Not quite. The difference is that the vast majority of people could not read, so they could not read the bible. Those that could, could not read Latin or Greek. This meant that the church alone had access to the Holy Scriptures. They used it for power and to pervert the Word into whatever would suit their needs, such as a crusade. When Martin Luther came and translated the bible into German, and then when Johannes Gutenberg invented the printing press, the common man could read the true message of the bible, which goes against the crusade mentality.
For Muslims, it doesn't matter how many people read the Koran, in fact it may even be worse the more that read it. Their Holy book calls for the killing and forced conversion of the infidel. They can't hide it and they can't change it. That is why they are stuck in the Dark Ages. Christian people can do bad things and Muslims can do bad things. If Christians follow the bible, they won't do bad things. If Muslims follow the Koran, then there will be a bloodbath.
