17. Perhaps you also remember the civility of the Civil Rights Movement

or the Indian Independence movement or Cesar Chavez, or the Singing Revolution where the Baltic states gained independence from the Soviet Union, the Velvet Revolution, the fall of the Berlin Wall, the People Power Revolution in the Philippines, the Cedar Revolution in Lebanon, much of the women's suffrage movement in the U.S., tree sitters in New Zealand.
