I think this is a very short-sighted view. The US has a long history of immigration, and of having insular cultures slowly integrate into some vague "mainstream" culture. Philadelphia had widely circulated German language newspapers well into the 20th century. Arguably, what has kept the US culture so vibrant is the very aggressive assimilation and acceptance of foreign cultures. I think the very notion of some sort of "American culture" that needs to be "protected" to be a fantasy; at best just a rose-tinted glasses view of the past, and at worst shorthand for "I want immigrants who agree with my views so that the candidates I support win more elections".
