“Cowardice asks the question, is it safe? Expediency asks the question, is it politic? Vanity asks the question, is it popular? But conscience asks the question, is it right? And there comes a time when one must take a position that is neither safe, nor politic, nor popular, but one must take it because it is right.”
~ Martin Luther King, Jr.
