Two things... firstly, as a matter of principle, in your first sentence you made a point then said it wasn't worth debating. If it wasn't worth debating you shouldn't have attached any argument to the statement.
Secondly,
Italy kind of needs as many non citizens as possible to become citizens. That is unless you can convince Italians to have more children. It's the easiest comeback to anti immigrant sentiment in Europe. Don't like foreigners... Rather than have a cry about it, have more babies.
It's the irony of nationalism in Europe today... Immigration is needed to balance low birth rates and an ageing population.
What the hell is "tempered nationalism" anyway?
Sounds like what every country already has based on their mere existence. I think what you're implying is less than "tempered"
Oh wait. that was three things.
