I don't recall the details, but as Spencer mentioned in the article, the Crusaders killed many people in the city. It was common practice at the time to sack a city that was taken by storm, and sack included indiscriminate slaughter.
Many Christians were killed, as well as most Muslims and probably Jews as well. Unfortunately, this was one of the periods in Europe when Jews were persecuted on a wide scale.
Post number 2 above references a book that may help.
To Muslim is Holy. Anybody become Muslim is Holy. One word from mouth, it is always correct. So, that mean no "liar". For example, if a muslim say "I like this girl". she will belong to him forever. Very strange, against freedom will. To them, they have right to conquer land. You must remember, they follow Abraham and 12 tribe of Israel in Canaan land. No matter how or what, they always right. Anyway, they are everywhere. The only best respond is to pray ROSARY. the only source of weapon that Mother Mary gave to us. Most important, Church must UNITE!!! Become ONE. I can tell you Muslim will felt to ground and start REVENGE and HATRED at us. Be on your guard and pray! MOSES use staff defeat egypt army, why not ROSARY conguer Devil!
