Wrong. And annoying.

The southern Australian cities of Melbourne and Adelaide have HUGE Italian expat populations. As does Toronto and Montreal in Canada. ALL these places are EXACTLY the same in their respective Italian communities regards keeping their Italian traditions alive whilst merging with their new 'Western' culture.
Italian Americans forget that when the great immigrations of the late 19th and 20th century were underway immigrants had a choice of the U.S., Canada or Australia..

The only thing 'unique' about Italian Americans is that like most other Americans who've never traveled further than a tank of gas, they think of themselves as being so. So before we all break out into chants of 'USA! USA! USA!' Remember there's a world out there which exists outside of the states.
