I don't believe the left is "treasonous." They aren't even "dissenting."
You're not dissenting. You're disagreeing, nothing more. To call yourselves "dissenters" is to cheapen TRUE dissent. True dissenters were found in the USSR and China and other brutal regimes - in those places, to disagree wis to put your life in danger.
You all sit in the coffee shops (fair trade coffee, mind you!!!!), and the art galleries and attned the "poetry slams" and talk about how you hate Geo Bush. That's hardly "dissent." It's just free speech. And you have the right to free speech. (I also have the free-speech right to say that your ideas are stupid.)
Frankly, when you "liberals" call yourselves "dissenters," it's OFFENSIVE. You put yourselves on the same level as the true heores who dissented against communism and other evil systems.
