A function of free speech under our system of government is to invite dispute. It may indeed best serve its high purpose when it invites a condition of unrest, creates dissatisfaction with conditions as they are, or even stirs people to anger. Speech is often provocative and challenging. It may strike at prejudices and preconceptions and have profound unsettling effects as it passes for acceptance of an idea.
William O. DouglasAs night-fall does not come at once, neither does oppression...It is in such twilight that we all must be aware of change in the air - however slight - lest we become victims of the darkness.
