Elie Wiesel said this quote

I swore never to be silent whenever human beings endure suffering and humiliation. We must take sides. Neutrality helps the oppressor, never the victim. Silence encourages the tormentor, never the tormented. Sometimes we must interfere. When human lies are endangered, when human dignity is in jeopardy, national borders and sensitivities become irrelevant. Whenever men and women are prosecuted because of their race, religion, or political views, that place must--at that moment--become the center of the universe.
