We all subscribe to the principle of religious liberty and toleration and equality of rights. This principle is in accordance with the fundamental law of the land. It is the very spirit of the American Constitution. We all recognize and admit that it ought to be put into practical operation. We know that every argument of right and reason requires such action. Yet in time of stress and public agitation we have too great a tendency to disregard this policy and indulge in race hatred, religious intolerance, and disregard of equal rights. Such sentiments are bound to react upon those who harbor them. Instead of being a benefit they are a positive injury.
