I thought, that for the sake of clarity and since the poor folks at the NW Folklife Festival apparently don't have access to a law dictionary, I'd quote this definition that I found online.

Unconstitutional - Conflicting with some provision of constitution, most commonly the United States Constitution. When a statute is found to be unconstitutional, it is considered void or as if it had never been, and consequently all rights, contracts, or duties that depend on it are void. Similarly, no one can be punished for having refused obedience to the law once it is found to be unconstitutional.

I think that the above generally covers why I'm so on about this matter but once again, for clarity's sake, they have no right, under law, enforcing the use of unconstitutional rules against our First Amendment right to freedom of expression. Why are they hell bent on punishing those who refuse obedience to their unconstitutional rules?
