Venetians, Sicilian, Lombardians and Neapolitans are not minorities, it is not an ethnicity, religion or anything. it's literally "people that live in X" and X is a region from Italy, literally one of the most industrialized countries in the world. It's like saying "new yorkers are a minority". Moreover, even if they were, literally nothing is happening to them.

Also, I won't give you something to hang on, so I won't say anything for sure. But I'm pretty sure most of the people in that list are in this same position.
