France too absorded millions of emigrants from Poland, Spain, Italy and Portugal (mainly) during the 20th century, without too much pain. But note the pattern: these are all Catholic European countries, and they were emigrating to a predominently Catholic European country (France). It was still pretty hard for them to get accepted, they were mocked for decades (called "rital", "polack", etc.).
Muslim emigrants today meet with much greater challenges.
As a boy in then very ethnic Detroit we had epithets for nearly every ethnic group including Poles, Jews, Slovenians, Slovaks, Italians and Irish. Very few of the kids I knew answered the question "What are you?" by saying "American". In most homes the parents or grandparents spoke another language, and Yiddish words were part of everyone's vocabulary.
I also knew that Northern Italians weren't very fond of Sicilians, just as Ashkenazi Jews weren't very fond of German Jews, though I didn't know (Or care) why. We also had lots of what we called "Syrians" and that they came in two varieties of both Christian and Moslem. It was much later that we learned that most were from Iraq.
All made serious efforts to adapt and become Americans, and the process was very rapid.
Moslem immigrants today experience more challenges only because the culture they are leaving (and in many or most cases bring with them) is itself highly intolerant of deviation. It seems to me that is their problem to solve - or, at least that only they can solve it.
