Let’s see. They are famous for:

• most of all, blasphemy and vulgarity
• drinking a lot (doing lots of coke as well)
• having lots of private businesses with dickensian owners

Let me add, as someone who’s worked there a lot, they are:

• misogynistic
• arrogant, they think they’re better than everyone else just because they stumbled upon the right conditions to make lots of money (there are other rich regions in Italy, none of them do as much dick waving as Veneto does)

Are there a lot of wonderful people? Of course, as everywhere. But the culture is rotten.
