I disagree, Jewish women and Italian women are not the same at all. The one key differentiator you forget to bring up regarding the east coast is that Jewish women are far more educated and classier as a result.Same type of woman, just one wears a cross, the other wears a star. The personalities are near similar. I've done intensive studies. Though, one can argue the one's from Queens are the worst.
Jewish women are likely to be found at top universities throughout the country and they take education very seriously. I find them mingling a lot with WASPs, Asians, and Indians here in the northeast as a result of running into them a lot. You will also find a lot of Jewish women in high paying jobs that are white-collar whether it is tech, finance, or consulting at big firms. If anything, I have found Jewish women to be almost identical to Asian American women in some regards. It is also somewhat common to see them going interracial and hooking up with Asian and Indian dudes, almost a thing now in NYC.
Compare this to Italian women. You are likely to find Italian American girls at "party schools", they are in overabundance at schools like Penn St and Syracuse. Most do not value education and tend to be the drugged-out party girl stereotype that loves drama. You'll typically see them going for sketchy white guys or douchey hot-headed Ryan Leaf type of guys. Most Italian American women are also very sketchy themselves.
Plus Italians here on the east coast are usually lower class and found in places like Staten Island. You will notice they have a lot in common with redneck culture whether it is overly patriotic for America, loving Nascar, chewing tobacco, and loving the Alt Right.
While I have seen black and especially Latino guys slay your typical East Coast Italian chick, it is very frowned upon to go interracial and they are quite racist. Unlike Jewish women who just want hot guys, Italian American women desperately want to be seen as whiter.
So I don't know what made you say the two have a lot in common, they do not.
Jews came to America and made it big, practically occupying the upper classes of this country. Italians are still stuck on organized crime and are very much the working class.
