Have you read books like "A Season With Verona" -- about jokes concerning death and morbidity? Maybe that's inexcusable, but to go with what Ciro found personally hurtful about the Vesuvius statements, that's par for the fans of the game for as long as time eternal. "Forza Etna" is a perfect example of this when Verona fans were away at Catania in the stands. Because the truth is that a lot of tifosi trigger off this -->
There's a sick streak of morbidity in the tifosi taunts. "A Season With Verona", for example, told of the celebration of offensiveness when the bus of fans sang a perversion of the Facist-era song celebrating propellers and aviators:
Gira gira l'elica, romba il motore
Questa è la bella vita, la bella vita dell'aviator
(Turn, propeller, turn, out roars the motor
This is the good life, the good life of the aviator)
But in light of recent events where a helicopter of carabinieri crashed in the sea, killing all aboard, they instead sang:
Gira gira l'elica, romba il motore
L'elicottero dell'arma è tornato a creator
(Turn, propeller, turn, out roars the motor
The policeman's copter has gone back to its maker)
That's not even about another team. It just illustrates a tifosi culture of saying the most offensive, morbid things as a matter of practice. Maybe this is part of the Italian tifosi culture we shouldn't be embracing, but I appreciate it all the more when, say, you contrast it with the louts in leagues like the EPL or La Liga.
