Answer:
One who uses his or her voice in favor of something
Explanation:
The speech this question is referring to is President Kennedy's Special Message to the Congress on Urgent National Needs, May 25, 1961
Kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:
<em>"Yet their aggression is more often concealed than open. They have fired no missiles; and their troops are seldom seen. They send arms, agitators, aid, technicians and propaganda to every troubled area. But where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in Vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)</em>
President Kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation.
