I love telling the story of the outward facing peace sign in our BU Boot Camps, as part of our “multicultural curriculum.”
In medieval times, archers were considered the “weapons of mass destruction.” When they were captured by enemies, their index and middle fingers were sometime cut off to prevent the prisoners from using their weapon against the captors in the future. So when archers were approaching enemy forces in battle, they would often dramatically hold up their fingers (with an outward facing “V”) to tell their enemies: “Look, I still have my fingers, you bastards. Now die!” The gesture remained and evolved into a general insult, especially in countries with British influence. Americans liked being different from the Brits, so we further evolved it into the one-finger salute (“shooting the bird”).
However, Winston Churchill also used a peace sign (forward facing) to indicate “Victory” at the end of World War II. And hippies from the 1960s and 1970s in America used the peace sign as an anti-war symbol. And the peace sign is also very useful at a pool table in applying the 30° rule. “V” stands for versatile!
I tell students to be careful if using the peace sign in other countries. I warn them to not lift it up and point it at a somebody with the back side facing out. The 30° rule peace sign is not offensive if you keep it horizontal and only point it at the balls on the table, as intended.
