I would have to strongly disagree. There are many different types of people in the USA. We have people from the South that are extremely different from those in California who are completely different from those in the North-East who are different than the North West who are different from the Mid West. There isn't one adjective that fits the whole country.

The South is more racist than the rest of the country, but you can't say the US as a whole is racist just because of them (their not all racist, there is just more racists there than in the other parts of the country). South West people are more "hippie-ish" than the rest. Each part is different from the others, so it's not fair to call the country as a whole one thing.
