Nationalism serves as a uniting force. The recent World Cup united each country, where people came together as aspirants for their team and, ultimately, their country. These fans were united in cheering for their players and equally united in recovering from defeat. This illustrates the spirit of national identity. By taking a strong sense of who we are, dishonor and fright become foreign concepts. We developed to be bold and confident, sometimes overly so. We become so occupied in our views that we drown in circumstances of opposition. We cross the boundaries to defame others in the name of unity. Unfortunately, that is where unity is no longer present, and the individual is singled out. Mistreating a national identity as superior is not appropriate. Although we are citizens of whatever country, everybody is a citizen of this one planet called Earth.
