I stumbled across this popular quote from MLK Jr. about courage and speaking the truth:
Deep down in our non-violent creed is the conviction there are some things so dear, some things so precious, some things so eternally true, that they're worth dying for. And if a man happens to be 36-years-old, as I happen to be, some great truth stands before the door of his life--some great opportunity to stand up for that which is right.
A man might be afraid his home will get bombed, or he's afraid that he will lose his job, or he's afraid that he will get shot, or beat down by state troopers, and he may go on and live until he's 80. He's just as dead at 36 as he would be at 80, and the cessation of breathing in his life is merely the belated announcement of an earlier death of the spirit. He died ... A man dies when he refuses to stand up for that which is right. A man dies when he refuses to stand up for justice. A man dies when he refuses to take a stand for that which is true.
So we're going to stand up amid horses. We're going to stand up right here in Alabama, amid the billy-clubs. We're going to stand up right here in Alabama amid police dogs, if they have them. We're going to stand up amid tear gas!
We're going to stand up amid anything they can muster up, letting the world know that we are determined to be free!
