"It's immigrants, (especially ones causing crimes against Italians) that Italians and Sicilians alike don't like. Causing crime in your own country is one thing, immigrants, such as the Romas coming in illegally and causing crime, that's another."

yes but you forgot that the vast majority of people imprisoned in northern italian prisons are not local, they are immigrants from southern italians... and the rest immigrants from abroad
northern italians hate southerner like they were foreign
and gypsies are not a problem in italy, they never kill at least they steal something 95% of murderers come from south italy
