First of all it shows that the splits among the Arabs go back centuries. Moreover, being shown the other side of the coin in respect of the crusades is a real eye-opener. When reading this book, the heroic pedestal on which the crusaders were lifted disappears like hot air. Intrigues for power, slaughtering, killing, raping - all this in the name of Christ, what a religion is Christianism? is there a difference to today's excesses by other religions which are so much lambasted by the western medias?? To be recommended for reading by all those condemning for example islamist extremists, it might make them talk a bit less loud.
