In our practice of kindness we should learn—first and foremost—to keep our noses out of other people's motivations. Verbally assaulting others with self-righteous zeal is a grave sickness of spirit. Certainly people act in ways that are worthy of criticism – but who are we to think that we have the authority to stand in judgement? It doesn't actually matter if we are right or wrong in our judgement. It is our motivation that is in question. Motivation and intention are primary in Buddhism.
