There was certainly a friendly rivalry between Chicago's Italian neighborhoods. For instance, there were social clubs that sponsored softball teams in both the The Patch and Taylor Street and they would hold tournaments. But in the end, it was not heated rivalry. Italians/Sicilians in Chicago stuck together. Both the Patch and Taylor Street were Mezzogiorno (southern Italian/Sicilian). Most Outfit guys were (and still are) Mezzogiorno. I agree with SP and do not think Taylor Street would be singled out or "hated" due to their neighborhood alone.
