These rights are further established by the first founding which hails the right of free speech as a democratic constitutional principle (American Government 4:9). Keeping this view in hindsight, the stance of the media in portraying her as a Muslin extremist merely on the grounds of her vocal protestations are indeed unfounded.
Having said that, it should also be noted that the Sedition Acts of 1798 prohibit any malice towards the government, or the Congress (American Government 4:11), including the expressions of dissent with the said authorities. Some states still strongly condone this acts, at least in their workings, and together with the state policies of Maintown prohibiting the desecration of the U.S. flag, Miss Nader's arrest is justified as she went against the set laws of the city in which she was operating.
America has always been a nation of liberty and freedom, and free speech is the cornerstone of this liberty. It's Constitution states that.
