I never liked the whole northern Italian seperatist movement especially since I am of southern Italian descent. I'll say horrible person.
Probably for the same reason Wallonians dislike flemish separatists: they know how much of a hellhole their country would be without the other part.
I'm not much of a fan of the northern Italian way of life anyway. I wouldn't really miss northern Italy (though the country would be poorer) but I do believe that the country should move closer towards more unified behavior instead of seperatist movements popping up.
