Express disapproval of a protester holding a sign that expresses hatred towards a certain group of people. Also, condemn "taking the knee" during the National Anthem and emphasize that it is not an appropriate form of peaceful protest.
Your "idiot", holding the sign saying "I hate Blacks" is not going to win many friends or influence people.  Just as the players who "take a knee" during the National Anthem are not winning many friends  or influencing many people.  There is a time and a place for peaceful protest.  Disrespecting the flag, as you can see by the overwhelming "blow back" these last few weeks, is neither the time or the place.  Sorry Charlie, the majority... from the President, the owners, the fans... all the way down to the NASCAR crowd agree on this one...  DO NOT DISRESPECT THE FLAG BY "TAKING A KNEE".
