  To a degree you are correct if you are saying the government cannot force you what to do or say, or what not to do or say to express yourself.  You need only to look at NK, to see why our constitution forbids the government to dictate how an individual can express themself. 
  
  However in the work environment outside the government, your employer/organization can dictate your behavior and what you say.
