"Injustice has a very dangerous ripple effect that must be combated right from the beginning. Imagine society as a pond disturbed by a pebble thrown into its still waters. The ripples created by this disturbance represent the far-reaching consequences of injustice. When a group is denied basic rights or faces [unreasonable] discrimination, the impact extends beyond the immediate targets. A ripple effect ensues, affecting neighboring communities and eventually damaging the entire social landscape. Grave injustices go on persisting everywhere around the world, including in democracies. Even if it is to a lesser extent than in totalitarian, dictatorial or autocratic regimes, it should never be underestimated or disregarded. That is the reason why social justice is increasingly put at the centre of international, national and regional policy agendas."
