Ron Paul said this quote

Years ago, a member of Congress slipped a laminated quote into my hand that he must have thought I would find meaningful. I paid little attention at first and unfortunately I don’t recall just who gave me the quote. I placed it next to my voting card and have carried it ever since. The quote came from Elie Wiesel’s book One Generation After. The quote was entitled “Why I Protest.”Author Elie Wiesel tells the story of the one righteous man of Sodom, who walked the streets protesting against the injustice of this city. People made fun of him, derided him. Finally, a young person asked: “Why do you continue your protest against evil; can’t you see no one is paying attention to you?” He answered, “I’ll tell you why I continue. In the beginning, I thought I would change people. Today, I know I cannot. Yet, if I continue my protest, at least I will prevent others from changing me.” I’m not that pessimistic that we can’t change people’s beliefs or that people will not respond to the message of liberty and peace. But we must always be on guard not to let others change us once we gain the confidence that we are on the right track in the search for truth.
