I would disagree - IF - you and your Italian friends are all the sons of guys made over in Sicily, and if you are using violence to enforce your extremely profitable rackets. You've then established your own family. Particularly if, to make a further point, you and your friends have racked up a higher body count than all 5 families combined in the last 20 years. If anything, maybe you and your friends are the ones now in a position to decide who's "Mafia" and who isn't.
