Definitive steps to overthrow the government is sedition, not treason.
Treason applies to actively supporting an enemy in wartime. Most of the use of the term ‘treason’ on FR is figurative, not legal.
Yeah, the term ‘treason’ gets thrown around more liberally than I’d like to see. It’s very clearly defined in the Constitution itself. Aid to enemies and the “levying of war” against the US.
