Thomas Lippman is a journalist who was stationed in the Middle East for many years. The way he writes, I get the impression that he is a Muslim himself, although the fact that he is a journalist helps him keep his objectivity. You get passages like, "This demonstrated that Allah was indeed on the side of the Mohammed." At the same time, Lippman doesn't hesitate to point out the many shortcomings of Islam as well, and its followers, but most of those he blames on politics, not religion. What's fascinating is that a significant difference between Christianity and Islam is that the latter doesn't believe in separation of church and state. What is law is based on the Koran, and on the many writings of Mohammed's followers, who apparently listened to his teachings to put together sharia, their code of laws.
I see some parallels between Islam and a fundamentalist Christianity that is long on law and short on grace. Muslims believe in one God, and don't believe in the Trinity, probably the biggest apostasy that Christians believe according to them. And I found it fascinating that originally Mohammed and his followers prayed facing Jerusalem, rather than Mecca, and worshipped on Saturday rather than Friday. Then they had a falling out with Jews in Arabia, and switched to Mecca and Friday.
There's a lot of warfare in the history of Islam, but if you look at Christianity, there was a lot of war there as well. And as Islam grew, it fell into factions, many of whom fell out of favor with the majority and did things that reflected poorly on the rest. The Taliban, the Druze and the Muslim Brotherhood are all examples of extreme factions who are Islam's version of skinheads and Hell's Angels. As Lippman emphasizes, the reasons they do what they do are political, but they try to use religion to unite everyone in a jihad against the West, just as white supremacists use Christianity erroneously.
All in all, this book probably won't appeal to everyone, but if you are interested in the topic, I found it an easy read and easy to understand.
