The earliest extant writing we have about mohammed's life was written 350 years after he died. It purports to refer to an earlier biography, written long after mohammed lived.
If the life of Christ were dependent on such historical sources, would anyone take it seriously?
But doesn't this demonstrate how important it is to focus on islam, and not on fascism?
You do know who Mussolini was don't you?
Anyway, before Mussolini there was Rome, and the one we know most about was the Eastern Empire. That's the one the Moslems picked apart piece by piece over a 700 year period. While doing so they gradually absorbed the facist technique, method, principles, and ideology.
