>>19654611Mostly regional, and sometimes ethnic. There's some broad general bits of American culture, like a very strong sense of individualism. Even people who like to sublimate themselves into a larger group (religious, political, racial, etc) do so on generally personal terms, and still view themselves as an individual. I've also been told by many foreigners, especially from Europe, that we're universally a loud people. We talk a lot and loudly, apparently. One problem is that the lowest common denominators of American culture has been exported globally for over 50 years, so many cultures have been Americanized whether you realize it or not.
Where the cultures really come alive are in the various regions. Southerners are talky even by American standards, and very friendly people usually, much more likely to say hi to strangers or be very gracious hosts. That being said, there is some distrust of outsiders because of the civil war and the disaster that was "reconstruction". On the opposite end of the same coast you have New England, which as the name suggests is rather parochial and similar to the rural parts of jolly old Ingerland. Reserved (by American standards anyway) and more softspoken. Except Boston. Which is a good segue into another bit of American culture, urban and rural Americans are wildly different no matter where you go, often holding entirely different values.
There's so many cultures in America I could make dozens of posts on the matter.
