All of these people I consider White. After all, "European people" is, in my interpretation, if it is being used correctly, a synonym for White. However, the people who run the greatest chance of non-European blood instead classifying them as a mixed race (and therefore non-White), in this case often a mixed race of Arab and White, would be the Italians. If Sicily were an independent state I would simply choose that instead, but since the entire Italian peninsula has been unified, Italy as a whole is the closest thing that can be identified.
