Speech: The American President

Audience: the American people,specifically Bob Rumsen,a man who disagrees with him.
Argument: The president is responding to a man who criticizes him and his views and actions. The president says that not only is America built upon freedom and free speech, but it's also about defending the free speech of a person who disagrees with you,someone who's beliefs you would spend your lifetime opposing.
Ethos: Since it is the president of the United States giving the speech, his position gives him authority. People respect him because of who he is and the status he has.
Pathos: The president makes reference to particular historic documents like the constitution and uses them to support his argument. The American people would relate to this and probably feel very emotionally connected to something like the constitution becuase of the values it represents to them.
Logos: After mentioning things like the constitution, the president continues by spplying it to modern day. He says that while we value free speech, it must be available to all, or it is not free. He makes a logical case for this.
Effectiveness: I believe this speech is effective because it draws from common beliefs and experiences and relates to all people and argues for a new way of thinking about things.
