The fact is they were not and you throw the term "traitor" and "treason" around without having the slightest clue what the actual meaning is. Treason is the only crime specifically defined in the constitution. If you read it, the relevant part says "making war against them". "Them" is plural. It means the states. It does not mean the federal government. The one who made war against them is Lincoln. he is the actual traitor to the US Constitution.
THEY LEFT THE US, NOT FOUGHT AGAINST THE GOVERNMENT. Waiting for you latest excuse.
