It is not a Myth! I was spit on in July 1974 as new paratrooper in the Atlanta Airport and called a baby killer by three teenagers (like myself). I immediately dropped my duffle bag and did the "Pitch Fork" lift shaking it and telling them that this was what it looked like when you got a live one. This was after they spit and started blocking my path. Needless to say, they were horrified and bolted away quickly.
Welcome home!
