Don't worry about it, it's just White people drama that should be resolved after the barbarians at the gates who can't or struggle to speak English and the traitors in government chambers, both of which are dedicated to sucking all the life and energy out of the nation, have been addressed.
I actually agree with this, but I also know that there were large issues with large amounts of Catholic (German, Irish) and non-Germanic (Italian) Europeans immigrating in the mid-and-late 19th century that forced the nation to shunter immigration in the early 20th to properly assimilate them for several generations. Even today we still get talk on Italian and Irish-Americans in the northeast having an inordinate amount of pride in their particular ethnic heritage.

In particular, to defeat
@Lip Glossary's insistence someone Off-the-Boat White is immediately assimilated in a short time, America waffled on joining World War 1 partly because it was justly seen as a European-only affair.... but also because large amounts of those Catholic Germans and Irish were
much more sympathetic to their mother countries (Germany and Ireland, eh) than the majority of Colonial-Stock-descended Americans who had more sympathy to Britain and France - who I might remind you
helped America achieve independence in the first place - and this was in 1914-1917, which is ALSO time for three and perhaps four generations of those German/Irish-Americans to have properly assimilated.
You would think if they were fully assimilated, they'd be down for helping the
actual mother country of America whose colonists invented the nation in the first place, or the nation that helped it stand on its own two feet and so they could move to it in the first place! It wasn't until they began to be seen as a fifth column when Germany was attacking our shipping did they finally begin fully assimilating, dropping German-language newspapers, etc. and we then join the war and saw the Krauts defeated.
If I were a White American of non-Colonial or Anglo stock, I'd see no point in denying it, but I'd also be honest that this was a country that was not entirely founded by my own and so I fully support the founding group and assimilate into its identity entirely. After all, they're the ones that created the land and nation, and set the tone and culture of it in the first place.
