As I said above, we can argue about whether those changes were good or bad. My point is that the changes were fundamental. The country was supposed to look more like New Hampshire than New York.
[1] I go to a church that happens to have a high representation of northeastern Congregationalists. We had an ice breaker activity where we went around and talked about what we liked to cook. They were almost apologetic about it. They started their stories with “well I grew up being taught cooking was just for sustenance, …” They cut donuts in half at events so nobody feels tempted to take more than they should eat. It is incomprehensible to me as someone from South Asia. But it’s the basis for a worldview that does affect how those people would run the country: https://www.nytimes.com/2018/12/05/opinion/george-bush-wasps...

How is it “prejudiced” against Irish or Italians to point out that their voting as a bloc fundamentally changed the country during the 20th century?
Irish people such as my ancestors fought and died for America in WWII. They were among the finest patriots who served the country.
