The last time I looked, the State of Georgia was the govenment there.
Now, if you want to argue that the Bill of Rights just applies to the Feds, and that the states can establish religion, ban guns, and control speech and press, force confessions, and arrest without probable cause, make that clear.
Also, the University I attend has a similar speech code and "free speech area". It works well, as I am not harassed by blue-haired weirdo peaceniks on my way to class. Our Young Republican group had a "Catch an Illegal Immigrant" Day and it went quite well. They've also held rallies opposing gay rights and were not disciplined for violating the code of conduct regarding hate speech.
