Agreed. I hate the term Calabrian vs Sicilian. I think that term was more prominent when it was Violi vs Rizzuto 30 years ago.
Desjardins/Mirarchi/DiMaulo were mixed Montagna/Arcuri/Gallo were mixed Rizzuto/Sollecito/Arcadi/[BadWord] were mixed
Maybe they still use that term because one group had backing of Ontario Calabrians and the term indicates an international conflict? Montreal itself doesn't seem to align as easily as the media portrays it.
