is that the problem? Are you saying that all the terrorists acts committed by muslims against the west are a result of the crusades over 900years ago!!!! If this is so my friend you have as they say been slipped a custard..who started the crusades? It took 460years of Muslim persecution of Christians in the Holy land before the crusades were called by Pope Urban 2nd. At the beginning of the fifth century, two hundred years before Muhammad appeared, there were seven-hundred Catholic bishops in Africa. Two hundred of them attended the Council of Carthage in 535 AD. By the middle of the 900s there were forty left. By 1050, as a result of 'peaceful coexistence,' there were only five left. In 1076 there were two. We learn this from a letter that Pope Gregory VII, 'Hildebrand,' wrote to Cyriacus, Archbishop of Carthage in June 1076. As three bishops are needed for the valid consecration of another bishop Gregory asked him to send a suitable priest to Rome who could be consecrated assistant bishop, so that he [Cyriacus] and Servandus, bishop of Buzea in Mauritania, and the new bishop could consecrate other bishops for the African Catholics. Did these Popes just disappear? When their churches were burnt and distroyed did they just peacefully move on..No they were killed...you know who by, part of your bloody history.
Your history like mine is full of blood. We cannot change that fact but we can make amends for it....that means forgiving each other for the past crimes of our collective ancestors, who I expect in the world and time they lived in felt they were doing the right thing. If we are to learn anything at all from history it should be when our ancestors get it wrong we should not be repeating the same mistakes. As I said already ...forgiveness sets you free. :)
