Professional athletes - football players, race car drivers, baseball players, hockey players, basketball players - from all the big dollar sports - ex-military men all, take a knee during the National Anthem at the start of all of their events, while those men who did not serve in the military stand at attention facing their fellow players. When the anthem is over, those standing reach a hand to those kneeling. They shake.
The leagues and the team owners support, publicly, vocally, all of these players.
During press conferences, all of these men speak out about free-speech and social injustice.
