So, this isn't covered by free speech? Look, the whole point of the 1st was to force ideas to compete in the marketplace for support. It is just as much their right (job?) to protest the war as it is our duty to refute their arguments and expose their motivations.
Now, admittedly, the success of the 1st is dependent on an open media; everyone here agrees on the current situation, which is why this is the first Fox and Internet war.
Let them keep protesting Bush and the US, and let us keep exposing their motivations. Support is still over 70% - a few more succesful days in Iraq and it will hit 3/4. That's how you defeat homeland communists.
