So Italians(and Irish, and Greeks, etc.) and any other "white" Europeans won't be discriminated against in America? Please reconsider the approach here, to imply that Italians faced no discrimination during this era is ridiculous. There was a significant portion of northern Europeans(and northern Italians, for that matter) who considered (esp. southern, though not exclusively) Italians to not be "white" like the rest of them, and tbh white basically meant Northern European at the time to many people in America. Additionally, as has been mentioned above Catholics and Protestants were definitely not singing kumbaya and dancing into the sunset in this era either.
At the very least heritages need to be somewhat more granular with north european and south european being separate for example.
