I found these in Aliran.

"I swore never to be silent whenever human beings endure suffering and humiliation. We must always take sides. Neutrality helps the oppressor, never the victim. Silence encourages the tormentor, never the tormented."
- Elie Weisel

"You have to do the right thing. It may not be in your power; maybe not in your time, that there'll be any fruit. But that doesn't mean you stop doing the right thing. You may never know what results come from your action. But if you do nothing, there will be no result..."
- Mahatma Gandhi
