body: I frequently see comments by semi-anonymous people stating that if an organization receives public funds then they have to respect people's freedom of speech, or they can't discriminate on the basis of sex, religion, or race, or they have to abide by some other well known provision in the US constitution.
  
  
  Is this true? Do Organizations that receive public funds really have to follow the Constitution in the same way that an arm of the government does?
  
  
  And If the answers is "Some do, and some Don't", then how do I tell the difference?
