Yes, of course. What I am saying is that when the Christians held Jerusalem, most of them didn't look upon Muslims and Jews as equals. They didn't respect them or think they had a right to be there. Thats why they were cruel, thats why Saladin declaired war on them (well among many reasons).
The movie focuses on people who have a sort of Utopian vision of the Holy Land. They think that everyone should have the same treatment and that everyone had a right to be there. I think it's unrealistic because, although some people thought that way, I'm sure, most people were how I stated in my first paragraph--they thought that they (Christians) were superior.
Love's a lovely lad
His bringing up is beauty
Who loves him not is mad
For I must pay him duty
