Those who have actually read it will tell you that it is filled with violent rhetoric. As the basis of a totalitarian religion one shouldn't expect much though it is of such poor literary quality (unlike the Bible) that one would think that an illiterate, uncultured camel jockey wrote it. Oh, one did.
If Islam were comparable to Judaism or Christianity the towers would still be standing and the world would have a lot fewer Christians killed by murdering Moslems. Thousands are killed every year by adherents to this murderous killer cult.
True, I have not read the Koran. But I saw Brian Lamb interview a former Catholic nun on C-SPAN. She had studied Islam and written on it. She said the Koran is a great poetic work, obviously divinely inspired. That's a former Catholic nun talking.
As for the Bible being well-written, well, I wonder if people are just reacting to the Shakepearean English. Much of the Bible that I have read is turgid and unreadable -- such as those passages that go on and on about measurements and begetting and such. My eyes glazed over that.
And the Bible is full of justifications for intitiating violence, cruelty, and conquest. Not all, but much. I tried to believe it as a kid in Catholic school, but rejected it when I found Ayn Rand in high school.
