In the words of the late, honorable Martin Luther King, Jr. :

“In the end, we will remember not the words of our enemies, but the silence of our friends.” 

“There comes a time when silence is betrayal.” 

“Never, never be afraid to do what’s right, especially if the well-being of a person or animal is at stake. Society’s punishments are small compared to the wounds we inflict on our soul when we look the other way.”
