When we are raised believing in a fundamental, it is very difficult to break it from someone. It is why practically everyone in the world that believes in God, believes in him. Not because they discovered him one day while reading a book, but because they were raised with that fundamental belief. People therefore get angry when try and change those fundamentals or disagree with. That is what I think is why the Middle East will not have true peace for many generations to come and maybe even never. They have the fundamental belief that the other side is bad. Ever since the days of the Bible there has been this struggle. It would take a new education in those countries to change this which I do not see happening at all unfortunately.
