As I always say, 'Merica is a meltin' pot of stupid; but that don't mean we have culture. The US simply doesn't have it in the traditional way we view culture, however. It's our country, obviously nothin' seems exotic or special if we've known of it for so long. The fact we don't have a long history means we can't look into a past as vast as any other society either. Our customs in those days are mostly borrowed anyways, and nowadays, we can't see them as unique cultural aspects. But they still are unique traits of American society. Just ain't particularly grand nor interestin'. 'Cept the Wild West 'course, but even then parts of that lifestyle are semi-borrowed from below the Southern border anyways.
... Now, if we didn't massacre them there natives on arrival, maybe we would'a had a less baseless start to our culture.
