Should MLK Day Be A Holiday?

Martin Luther King Jr. day is an observance of Dr. King who was the chief spokesman for nonviolent activism in the civil rights movement, which successfully protested racial discrimination in federal and state law. It is observed on the third Monday of January each year, which is around the time of King's birthday, January 15. This year of 2011 it falls on January 17, and marks the 11th year in which it is observed in all 50 states. The campaign for a federal holiday in King's honor began soon after his assassination in 1968. Ronald Reagan signed the holiday into law in 1983, and it was first observed in 1986.
The Berlin Wall was a barrier constructed by the German Democratic Republic (East Germany) starting on August 13, 1961, which completely cut off West Berlin from surrounding East Germany and from East Berlin. Eventually on November 9, 1989 The “Iron Curtain” fell, and West Germany was reunited with East Germany. All though the entire wall did not fall on this day, it is the day that symbolizes the reunion of Germany, and is not celebrated on this day because of previous events that have occurred. Even though it is not a yearly celebration on that day in Germany due to other previous events in History, why can’t it be celebrated in the United States?
If the fall of the Berlin wall is just as significant, if not even more significant than MLK day why is it not celebrated? To me the fall of the wall signifies the beginning of the end of the Cold War, and Dr. King is a very important person in history he is just one man who lead the civil rights movement not the civil rights movement itself. He did not start the movement and was not the only person or part of any one group pushing for equality. The Berlin Wall was set in place to “Protect Fascism,” some people believe that it was set in place so that people in East Germany would not flee to the West and that would cause the Soviet Union to lose power. The fall of the wall symbolizes the fall of Fascism, and the start of a unified world full of information available to the general public and freedom. If the fall of the fall of the Berlin Wall is not a day to be observed, then why should Martin Luther King, Jr. day a federal Holiday?
