The Inter fan is immunized against all dangers: one may call him a wiretapper, a passport counterfeiter, a coffee tampering doper, a prescritto, a cardboard collector, a Coppa Uefa hotshot, a leech living off tribunals or ndrangheta, it all runs off him like water off a raincoat. But call him a sfinterista and you will be astonished at how he recoils, how injured he is, how he suddenly shrinks back: “I've been found out.”
