Don't forget the concept of Italy as a unified (political) nation is only 150 years old. Many still consider themselves to have a stronger regional identity and still use a dialect.
(PS I used to live in Italy)
I went to Alto Adige a few years ago hoping to improve my Italian and found that German was the first language and they felt more affinity with Austria than Italy.
No need to apologise! Your post demonstrates a reasonable level of ignorance of politics in Italy and Lega Nord in particular, which is fine since I'm guessing you've never lived there? Reading about the background and idealogy doesn't give you any sense for how Lega is viewed in Italy, nor how politics works there. No point in getting dragged into a political debate here, but the concept of a Tour of Padania would seem as natural to any Italian (including those from the south) as a Tour of Britain. Most people would just laugh and carry on - kind of the Italian way - and treat it for what it is, a bike race, and enjoy the cycling. It's just the way it is there / here (I live in Milan half the time).
Furba is a word which sums up the Italian psyche, meaningcolloquially that despite recognising that cheating and malpractice is wrong, it is nevertheless something to admire, and the bigger or longer the slyness and cunning, the greater sneaking admiration.
Much as I'm enjoying the spirited come-back, I think FM is right, and though I don't dispute that a lot of people (both here and there) might shrug their shoulders at the whole affair, as a caricature of Italians as a whole it's slightly patronising. Presumable Bugno is being terribly un-Italian when he says "Everybody should have understood that the race would have been linked to a very distinct political party. They should have said no. Everybody should have said no."?
