No problem, Brian...
As I wrote I don't feel resposable for what italians did years before my birht! And I'm not just talking about the last war: I coud go back to the colonial wars too, and the piedmontese "invasion" of southern Italy, down to romans and etruscans!!
There is an italian "core" in all the people who lived this country in the past, but I don't agree with anything they did of course; they're not "me" so I don't feel hungry if someone offends them.
Useless to say that that anyone should understand that later italians are different from the former... just like in any country!!
