On some positions, Cowardice asks the question, “Is it safe?”
Expediency asks the question, “Is it politic?”
And Vanity comes along and 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 he must do it because Conscience tells him it is right.

-Martin Luther King, Jr.
