I get that the word itself has other origins, but the word in and of itself is Italian. There are words even throughout the English language that is rooted in Greek, Latin, etc, they have counterparts and derivatives if you will, in other languages, but they're still English words. Some people don't mind it, and are okay calling every criminal group out there Mafia, but others like myself are a bit put off when we hear Irish Mafia or Chinese Mafia. But call it whatever you want.
