Bravehearts by Joseph Ruffo

It is the soldier not the reporter who has given us
  the freedom of the press.


It is the soldier not the poet who has given us
  the freedom of speech.


It is the soldier not the campus organizer who has given us
  the freedom to demonstrate.

It is the soldier who salutes the flag,
  who serves beneath the flag, and
  whose coffin is draped by the flag,
  who allows protesters to burn the flag.
