Americans are the citizens of the United States of America. They are of any skin pigment and any religion (or no religion at all). They include a large diversity of political views. They are rich and poor, they are of most classes.
Americans come from all backgrounds and all nations on earth helped form this multicultural society.
Remember, kids: just because you meet or hear one person from a certain place doesn't mean that everyone from there is like it. Oh, and did I mention that the actions of the former US government didn't ALWAYS speak unanimously for every last citizen of the USA? Just wanted to clear that up. We don't hate all Canadians, Brits, Cubans, and Japanese people. We don't think all Muslims are terrorists. No matter what Bush said, we most definitely don't eat "freedom fries". We don't all support Iraq. We don't think Pakistan is in Africa. Americans don't conform to any one stereotype. Most of us don't even like Bush anymore. We voted for Obama.
