Islam is built on the principles of submission and dualism. The very word Islam means submission. It does not mean peace. But submission to what and who submits?
The submission must be to the doctrine of Islam. The doctrine starts with the Koran, which says that all of the world must pattern every detail of their life on what Mohammed said and did, the Sunna. All of the world must submit to the Koran and the Sunna of Mohammed. Another way of saying this is that all of the world must submit to be ruled by the Sharia.
The Koran and the Hadith say that all of the world, every single person, must submit to Islam and obey the Sharia. So the concept of submission is absolutely totalitarian. All other forms of government and religion and philosophy are man-made and must be replaced by Islam.
