Do any Americans do that? Is America in your personal top 5?
As a matter of fact ... no, they don't.
I live in Los Angeles. A place where 40% of the drivers are unlicensed and uninsured, not to mention, not here legally (three crimes right there, no?).
I make a phone call to a service agency, it says "Press 1 for English" and if I don't press 1, it continues in Spanish as the default. I've been in line behind people speaking Spanish, with five kids in tow speaking only spanish, using food stamps in excess of my entire monthly grocery bill. I have personally witnessed my property being stolen, and the side of my house being vandalized, by people coordinating these activites completely in Spanish. And worse.
I consider all of the above patently UnAmerican.
And if 90% of the crime in my neighborhood was committed by Scottish People, I just might call for tighter restrictions on Scottish Immigration. But .... they aren't scottish. And you know they aren't.
The emporer has no clothes.
I guess somebody's gotta say it.
