Oh no, there is no comparing Sicilians to Africans. Sicilians are Africans according to other Italians on Italy proper, as well as other Europeans. Fact is, sure, originally it was a Greek Island, and it's gone through a succession of occupations, including Moors from North Africa. Even after the Normans wrested control from them, they still retained many aspects of Moorish culture. You can see it in your cathedrals and place names.
English, Germans, French, Scandinavians... Do not consider Italians to be White. White Americans - Anglo-Americans - do not consider Italians to be White. Blacks do not consider Italians to be White. Germans do not look at Italian as White. Hitler allied with Mussolini's Italy to use them, but he never ever included them in his master race. It's funny because he copied much from Mussolini, but he still look down on him.
Perhaps you should look this up and do a little learning before talking about that which you know nothing about.
