Don't even bother, mob started because the gov't in Rome could care less about Sicily so it was the old west. The mob moved in because of the lawlessness. They're not descendants of Muslims.

No, that post isn’t stupid. Muslims lived in southern Italy for centuries. A lot of the culture of this area is taken from that era. It was later mixed with other factors. I don’t remember the details well enough to be more specific. But the basic facts you are responding to are correct.
One of the most uninformed posts I’ve ever seen. Italy was subdivided into a number of independent states until modern Italy was founded in 1871. Here’s a website to give you enough information to engage in meaningful dialogue in the future: http://library.thinkquest.org/TQ0312582/unification.html
