Sir: rights work in both directions, ie the players have a right to protest, and I have a right to protest their protest.  To display their protest in the faces of ticket-buyers and show watchers is the wrong venue for expressing their concerns.  Let them do radio, TV or sports magazine interviews--places where IDEAS are DISCUSSED--to get their message of concern out to the public.  By protesting during the anthem, the players are not discussing or debating in the arena of ideas, they are slapping viewers in the face with their opinion.  This naturally causes a hostile response, which we are seeing in the loss of revenue to the NFL.
