It is not enough to 'fight' Islam. You also have to remember that its power comes from its high birthrate. Therefore, the business world and the political world will bow to it for their own needs.
Christian and secular societies are (rightly) seen as declining and belonging to the past, while Islam is seen as the future. Only by returning to the true practice of Catholicism, can this be reversed. It is the only hope left for the 'disappearing' non-Islamic world!
