Can We Be 100% American?

Can we truly be a 100% American culture? With America having so many diverse cultures it is known as the melting pot. Everywhere you look you will see someone of a different ethnicity or cultural background, but will you ever see someone who is truly American? People of America probably never stop and think am I really an American?
The people of America have adapted to so many different cultures and don't even realize that they are doing it. If you look at the food you eat or the clothes you wear, where do they come from? Chances are that the pizza you may have had last night was resemblance of the same pizza made in Italy. The clothes you are dressed it right now where did they come from, probably Mexico, China, or Thailand.
Does the American culture have anything of its own to offer the world? If you really look at it no, we really don't. So if we have nothing to offer how can we be an true American culture? The answer is simple, no we cannot be a true American culture. This does not mean you cannot be an American. If the whole American population has adapted this mixed culture you can be apart of that. What it means to have an American culture is to accept, and live out the mixed and diverse culture that the country as a whole has also accepted. Even if the people accept the culture that we have adapted to you still will not have a 100% culture. This is due to the largely diverse ethicality though out the country.
