Perhaps you shouldn't be in such a hurry to toot your own horn. WhiskeyPapa said:
"...no one has EVER been hanged for treason in the United States..."
And by your own admission, John Brown was hanged in Virginia, which was in the United States, for treason against the Commonwealth of Virginia.
Saw your posts, and just offhand, creating a dispositive distinction between "treason" and "raising insurrection" is mighty thin. These word quibbles need something to eat.
John Brown attacked a United States arsenal with a force of armed men and killed federal troops. Hooting because the word "treason" doesn't appear in the articles preferred against him doesn't strike me as a victory for truth and beauty.
