Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort.
Attacking the government of the United States of America with clear intent to overthrow it certainly meets either definition. Any other similar attack is "only" terrorism. Treason, however, takes it to a whole new level.
Good luck with your little revolution against the most powerful military in the history of mankind. And lest you think that a sizable number of troops would join the traitors, let me remind you of how horribly wrong many revolutions in the past have gone. You do pay attention to events, past and present, outside our borders, right?In fact, the use of the country's military resources to wage war against its own people—a practice which you seem to advocate—would meet the definition of treason.
If advocating treason should be punishable by hanging, then let us start with you.
