In no way shape or form can you equate the Bible with the Quran. To do so is (within the context of each book) a kind of act of violence against both religions.
It would be like a king putting a throne in the white house, or placing a fresh water fish in salt water. The two books are not equal, they are not of the same beginning or end. They do not teach the same understanding of reality.
As for me, in my opinion, its is always illogical and morally wrong to justify violence in the name of Christ (if you go by Christ). But it is not always wrong to do violence in the name of Allah (if you go by Muhammad). However, in Christianity there has been much violence in the past. But when you look closely at those times, you will see that much of that violence was politics disguised as faith. Especially within Catholicism, where the papacy is both a religious office and a political one (though it was not meant to be).
It is easy to make a fool of someone who cannot read. And most solders of any religion are illiterate. That is true of Christianity in the past, and of Islam now. But if you ask me if I think that the Muslims would be as violent (or tolerant of violence) today if all Muslims could read. I would answer yes... Regardles of how the quran is translated or interpreted. Because fundamentally, Islam calls for obedience, while in christianity it is more important to love than obey. It is not a simple distinction.
edited a point for accuracy.
