Pearl Jam has a music video of the song "Jeremy" in which the "gutsy" producer of the video flashed for a split second a classroom full of children doing the early American stiff-armed salute (the Nazi salute) to flag during the Pledge of Allegiance. The pic is at 3:30 in the video linked below. Pay close attention cause it flashes by.
The video is an example of how paranoid people in the USA are about ever discussing the truth about the pledge of allegiance and its putrid past.
The pledge was the origin of the Nazi salute and Nazi behavior (see the discoveries of the historian Dr. Rex Curry). The early pledge began with a military salute that was then extended outward to point at the flag (thus the stiff-arm gesture came from the pledge and from the military salute). http://rexcurry.net It was not an ancient Roman salute (that is a debunked myth). The pledge was written in 1892 for kindergartners to be forced to recite under the flag at government schools (socialist schools). The pledge was written by an American socialist who influenced other socialists worldwide, including German socialists, who used the gesture under their flag's notorious symbol (their symbol was used to represent crossed "S" letters for their "socialist" dogma -another of Dr. Curry's discoveries). The pledge continues to be the origin of similar behavior even though the gesture was changed to hide the pledge's putrid past. The pledge is central to the US's police state and its continued growth. No one should stand for nor chant the pledge.
