Just as a matter of interest, I'm curious to know how exactly the "billion" could express themselves thus collectively in a manner which you would find acceptable? What process would you envisage which would might gradually secure the trust, or at least moderate the distrust, of the rest of the world's population?
Given that one is constantly told that Islam has no heirarchical structure, and therefore no means of disseminating a central authority, it does seem to me that any peacable Muslim majority, assuming for a moment that it exists, would find it extremely difficult in the current climate to moderate the prejudices now established against it.
