Furthermore there are limits to free speech in the US. For example: obscenity, treats of violence, military secrets, etc.
Australia has no bill of rights, yet judges have upheld individual right to protests (Victoria has a Charter of Rights, but that's it). China has free speech in their constitution. Germany has free speech, unless it has anything to do with the original Nazi party symbols.
You really think that these laws have never been challenged before?
Fraud has been illegal for as long as the US has existed. It's not protected. If it was protected as free speech, fraud laws would have been overturned sometime in the last 225 years.

In Dred Scott v. Sandford the court ruled that the bill of rights does not apply to African Americans. Are you a supporter of that decision or did you mistype? Where does it say that the court gets to supersede the constitution? I think you will find that it does not.
