How Many People Has Islam Murdered?

Infidel Bloggers Alliance has a post today about a new book on Islam.  That's it on the right -- Islam: Evil in the Name of God.
..
The author of the book points out that Islam is actually a declaration of war on all kafirs -- those of us who do not believe in Islam, Allah or Muhammad.  He is only partially correct in this.  Islam is a declaration of war on all humanity.

Over the centuries since Muhammad the Megalomaniac invented his nasty little religion, his followers have murdered millions in the name of God and continue to add to the tally to the present day.

I find it interesting that the author of this book states that 270 million people have been murdered by Islam.  I have always wondered how high the number goes.  I have read that as many as 100 million Hindus alone have been murdered by Islam, so the figure is believable.  That's almost the current population of the United States!

If so, then I would agree with the author that Islamic murder constitutes the greatest holocaust in history.
