The root of the problem is that for much of our history there has been conflict. To Western schoolchildren, the Crusades are traditionally seen as heroic. To Muslims, the Crusades were an episode of great cruelty. To many people in the West Islam is seen as a tragic civil war in the Middle East and Islamic Fundamentalism. Our judgement has been distorted by taking the extremes as the norm.
People often think that Sharia law is unjust.
We need to study its application before we make judgements. There are some Islamic countries that gave women the vote at the same time as Europe. Islamic women are not automatically second class citizens. We in the West need to understand the Islamic World's view of us. Many Muslims genuinely fear the West and see it as a threat to Islamic culture and way of life.
