No, free speech isn't free.  It was bought and paid for over and over again ever  since "the shot heard 'round the world" in 1775  by soldiers who selflessly  gave their lives then, so we could do what we're doing right now.  College campuses today have become the polar opposite of what our founding fathers designed, fought for and died for and passed on to us.  

We can all rest assured as Madonna has proved free speech still does  exist with her foul "public" language and her  desire to blow up the White House during the "family friendly" women's march in  DC this past January.  Is she in jail? As far as I know, she isn't.   According to you, a bad day is all she gets for her threats. Maybe she did have one.
