Not really, all the NYC folks I know proudly claim they are different. What disgusts me is all you folks would not have said a word if Trump said the same thing about Iowa. People in the heartland would have said “damn right we have different values than NYC.”
The fact remains that the most politically vocal "New Yorkers" are leftists who have moved to New York from other states.
It's very tiresome for those of us who were born and raised in New York City to hear the constant: "Well, I was born in Anytown, USA which is so backwards and superconservative and now I feel like I'm finally home among my real people" stories.
Then they get annoyed when you point out to them that almost all the people they congregate with and feel at home with in NYC are fellow Midwesterners, Southerners, Westerners, etc. who all have the same sob stories about how they had to go to Sunday school and Wednesday Bible study, and football games and eat loads and loads of barbecue and other atrocities.
Meanwhile, many of us locals went to CCD or parochial school, and First Fridays, went to basketball and baseball games, and ate tons of pizza, etc.
Native white Christian ethnic New Yorkers are the most conservative people in NYC, and also only 50% of the white population and 15% of the total population.
Yet the classic idea of a New Yorker in most people's minds is either a blue collar white Irish or Italian dude shouting "Yo, your team sucks! Let's go Yankees!" or a slick banker or lawyer.
The former is a local and is typically patriotic, pro-military, goes hunting and fishing, to church on Sunday, does all the normal American cultural activities. They are the 20% of NYC who voted against Obama.
The latter in real life is usually an import from elsewhere.
