Among the liberties of citizens that are guaranteed are ... the right to believe what one chooses, the right to differ from his neighbor, the right to pick and choose the political philosophy he likes best, the right to associate with whomever he chooses, the right to join groups he prefers.

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.
