I think that Muslims are taught this profound hatred since birth, and it just does not go away. It is part and parcel of these "human beings". Those of us in the Western World have never experienced anything like this.
I have a Saudi Arabian aquaitance, who seems to be kind and normal in every way, but when a Jew is mentioned, he just goes beserk. He is one human consumed with hatred for the Jewish people, and this has been taught to him. He has studied Islam every day of his life.
The teaching of hatred/bigotry is just so sad...lifes too short to go around hating everyone of a particular race-color-creed...there are good people everywhere just as there are bad.
In the end Good must triumph over Evil.
