Why are you making the generalization? While all muslims weren't peace loving, Salaudin surely was. And he was a great ruler.
And its a historical fact that he allowed the christians safe passage. Was it becuase the city defences forced him to, or his kindness we shall never know. But none the less, he did.
did you read the article? you are kidding, I hope. Saladin was ruthless and sadistic.
