I have started reading the Koran. It is generally assumed that since it is the holy book of a major religion it must somehow resemble the holy books of other religions. It doesn't. For one thing it was written by only one person. The Hebrew bible was written by dozens of hands over a period of almost a thousand years. Its heterogeneity reflects its authorship. The New Testament is a compilation of writings spread over more than a century and also done by several hands. So are the Buddhist sutras. No word of Hebrew, Christian, or Buddhist scriptures is believed to have been written by Moses, Jesus, or Gautama. Every word of the Koran is attributed to Muhammad, the founder and prophet. All of these literatures reflect the character and personalities of the folk among whom they arose as they evolved over centuries. But the Koran reflects only the personality and mood of Muhammad.
Unfortunately Muhammad, when he was writing the Koran, was embittered and resentful. The first chapter, 'The Cow' (which has nothing to do with cows), is an angry man's private ventings of spleen, made into scripture. Unfortunately most of his angry ventings are against the Jews and the Christians. He is quite explicit that the reason for his anger is that both refused to accept him as their messiah. Both refused to change their religions to accomodate him.
I expected that the text of the Koran would be a mass of pious exhortations and an occasional unkind word about the Jews or Christians here and there. Quite the contrary. The great majority of the text is composed on the same verse form. Each verse begins with three or four sentences denouncing Jews (whom he calls 'evil-doers'), Christians (whom he calls 'those who anger G_d'), or unbelievers generally. Occasionally he denounces idol-worshipers by which presumably he means the illiterate pagan Arab tribesmen whom he recruits. The last sentence of each verse is generally an admonishing platitude about G_d.
He says explicitly and repeatedly that it is the duty of Muslims to fight against unbelievers. So much for the 'Religion of Peace'. In most Muslim countries, education consists in large part of memorizing large parts of the Koran. I hope the rest of the book will be less scolding and angry and contain less violent language.
So far my conclusion is that we have been kidding ourselves in believing there is such a thing as a moderate Muslim. Judging by this text, that is an oxymoron. So far as I have read, the bulk of Muslim teaching consists of exhortations to hostility toward Jews, Christians, and pagans.
Our problems with Islam will not go away soon. 'Live and Let Live' is NOT what they are taught. The only way we will ever find to deal with people who accept the teachings of the Koran will be by force and by isolating them. They will ALWAYS attack their non-Muslim neighbors.
