In a true & democratic society working to promote the advance of civilization there can be NO SUCH THING as TREASON.
What else will we call it?
Democracy does not mean that everyone gets their way.
Democracy does not mean that there are no rules to follow.
In a democratic society, treason could be nothing other than what it is in any society: acting against the will of the government through unlawful means.
As for the 'true & ... working to promote the advance of civilization' part, that is just nonsense. What worse society to live in than one that puts other ambitions over itself? Who cares about the 'advance of civilization' while people are starving? Or how 'true' the democracy is that can accomplish nothing?
You've got yourself a nice fantasy, xong; but that's all it is.
Treason is treason. Not by design, but by simple reason.
Love your enemies!
