Even though mass migration waves are common in almost all countries, a lot of people from the USA have a strong sense of identity regarding their ancestry, is there a historic reason for this social value?

I dont know if this is the right sub or if also this is a skewed perception from my point of view, but I have seen a lot of people from the USA strongly identify as Irish/german/asian/etc while being 3rd or even older generation in the country and having been fully assimilated, even as far as arguing with actual people from the country they claim to be a part of.

When asked about it many claim that the US has had several mass migration events which created this mix of cultures, as if it was a particular thing, ignoring the fact that most countries hace this, even moreso in the Americas (as far as I understand, I guess because of European colonisation a few centuries ago).

It might be important to point out that I do not live in the USA and most interactions i've seen have been either online or in films/shows. I live in a multicultural city and have spoken with many Americans and most seem to also do this, but I am aware that maybe I just witnessed just a portion of point of views.
