Most countries regard the United States negatively because of how our government chooses to act regardless of the majority of the population. They see us as fat, violent, uneducated and completely cut off from the rest of the world.
While a lot of us are overweight and obese, and our education system below university level is not up to par with other smaller, more economically stable countries (Netherlands, Finland, etc.etc.), we're really not much different from Europeans. Most of us are non-violent and have a certain, if uneasy, respect for the law. Sure, we like our Bill of Rights, but why shouldn't we?
