Italians, Italian Americans, and Italian Americans from either NY or NJ are all different species. TBH, I have had a really good experience with Italian women from Italy too and find them to be classy and rather chill, this is more true the more north you get. A lot of them are a bit shy and surprisingly sheltered compared to their European sisters from elsewhere. If you play it right, can definitely have some great potential for wifey material. Now obviously this is the case since they are traveling, from what I hear they are really stuck up and mean when in their home country.
Italian Americans in general are no different than Americans of other European descent groups. In other words, a basic white person.
However, Italian Americans from NY and NJ, especially if we are talking Long Island, Staten Island, and Bergen County are a special level of trash. There is a saying out there that "you can't buy class" and these people are the embodiment of that. A lot of them are new money wealth but are often the trashiest people at bars, clubs, and in public.
The women are nothing to write home about either. No matter how much money she has, she still acts like gutter trash. Truly some of the most toxic and awful people you can be around.
