Query: Bad bad book

Ok, the author says we christians massacrated the islamic culture in Spain. According to him, the moors were so superior, superior to those "barbarians" as all the time he calls the christians in his book. Disgusting kind of literature. Isabel of Castela was the greatest stateman (or statewoman) of her time, and she is described in the book as a bloody fool, thirsty for moors' blood. Come on! The author does not understand that it was a mere question of politics, the reconquer of Grenade. Another fact that made me sick: the moors were not violent! No, when they invaded the south of Portugal and Spain, it was a desert, nobody's land. Really???
