They should be free to voice their concerns for however long that takes, then they should shut up and go home. Most people have enough smarts to absorb their points the first time.
Did you actually say that???? Maybe since you have voiced your concern here you should now shut up and go away. It can hardly be called freedom of speech if you can only say something once. It is not freedom of assembly if armed thugs can pepper spray you or worse because their bosses don't like what you have to say as a group. Really that is what this is all about nowadays. If the government doesn't like what you have to say, if it disagrees with the government agenda, they send in armed police to trample your rights and cause you physical harm if you don't comply. We are living in nothing more than a dictatorial police state....that simple!!
