Tolerance is a form of generosity and it is a form of wisdom. There is nothing anywhere in the Dharma [Buddhist scriptures] that should ever lead anyone to become intolerant. Our goal as Buddhists is to learn to accept all kinds of people and to help all kinds of people discover the wisdom of the teachings of Shakyamuni Buddha
