I suspect you aren't being serious but in the US there is a huge difference between the folks in rural south and cities of west and north east. I guess that is kind of obvious but having lived in several cities in the north east/west coast and growing up in the south it always shock me how attitudes and education changes across the country. As a tiny hint I took a summer job one year in the south east and one of the full time employee said something along the lines (paraphrase as it was 30 years ago) "Its a good thing you applied we were afraid we were going to have to hire a nigger". I was actually a bit shocked because the city i grew up really didn't have much racism but this was a bit further south east then where i lived and the open hostilities across racial lines was rather blatant.
I was talking about needs and what drives us at the core.
Meaning, if you take two infants from completely different places in the world - and subject them to 100% identical circumstances from early childhood to adulthood - you will find two very, very similar human beings.
Hint before someone says something: Twins do NOT experience anywhere near identical circumstances. From the moment your senses come into play - as a human being - every human being will experience the world in their own unique way, because every input matters.
If you step out the door for the first time in your life, then the weather, the people you meet, the smells you smell - and so on - all play a part in your response to what's happening.
One child might step out the door and experience a warm summer day - full of friendly adults. Another child might step out the door the next day, and experience dark, rainy weather and be bullied by the local dumb brute. When you're a child, you have only your first experiences from which to form your worldview - and it doesn't take a lot of bad experiences for them to get stuck as part of your core personality. That's how human beings work - and that's why the first 3-6 years of our lives are the most important when it comes to the very core of our being.
They might live in the same place, have the same parents, eat the same food, and so on - but that's only a tiny part of what makes up the human experience.
Of course, genetics play a part - and if there's some kind of physical or mental defect that's present at the time of birth, then circumstances can never be identical.
The ultimate point is that Americans aren't this one thing - because the country is vast, and they've all got their own unique perception and sense of the world. Of course, they will be affected by the american culture and american values - but that doesn't mean they all interpret them in the same way - or respond positively to everything they're told.
