In this specific case is it the law that's restricting his speech, or the licensing's boards actions? I'm not necessarily taking an opinion on the actual merits of the case in the article, if anything I does sound like they are infringing on his right to free speech. But that doesn't necessarily mean the law is unconstitutional. It's easy to say something is or is not constitutional, but the end of the day we have courts to decide these questions. If I still disagree I feel strongly about it I need to contact somebody who can actually change it. Am I really going to make my beliefs about what is or isn't constitutional based on some comment posted on the internet?
