So you're saying this is Constitutionally protected free speech?
Good lord. You could look into a bowl of alphabet soup and read a novel out of it. Look at what I excerpted. It shows to what I am replying.
Constitutionally protected speech, yes it is.
You can rant all you want as long as you do so as a private citizen but that right is tempered by where you are, and in this case, the AFA has published standards of behavior and rules regarding conduct, dress and appearance.
