The Post’s Sept. 25 editorial “They don’t have to stand for it” brought to mind a letter preserved in the Manuscript Division of the Library of Congress. When I worked as a specialist in the division, I would often proudly show the “Gobitas letter” to visitors.

The letter was written in 1935 by 10-year-old Billy Gobitas to his school explaining why he was refusing to salute the flag. Because the Supreme Court eventually upheld his right to do so, this letter should be seen and read by all Americans today — especially the current White House occupant, who regularly demonstrates his indifference to and ignorance of our history. Kudos to The Post for citing this landmark case and pointing to it in a lead editorial.
