It is painfully obvious that most people are ignorant of history and need to study it more. Here is an excerpt of an article that should be read so you will have a better understanding of the true nature of Islam.
Muhammad established the belief among his followers that God had commandeered all Muslims’ purposes and property for His efforts and that all Muslims had a responsibility to fight for the faith. Everyone—men, women, and even children—had an obligation for military service in defense of the faith and the ummah that was the community of God’s chosen people on earth. It is essential to understand that the attraction of the Islamic ideology more than anything else produced the manpower that permitted Muhammad’s small revolutionary cadre to evolve into a conventional armed force capable of large-scale engagements.
And here is a link to the article although there is a lot more out there you should study so you have a clear understanding of what the world is up against.

Plus, Al wants to make sure that he gets his songwriter credit (as writer of new lyrics) as well as his rightful share of the royalties.
