How does free speech die...

With quiet applause apparently.  Sitting on an airplane I noticed a young man spewing vulgarities and singing. Two flight attendants asked him to stop and then kicked him off the plane.  This was responded to via quiet applause.  I

came to the boys defence only to find that people no longer care about protecting offensive speech.   Passengers went as far as saying that cuss words aren't speech, and  that I was the one with the problem for defending his right.  I guess that free speech fell with the Trade Towers....
