Ah, the "heckler's veto". 
Let me see, the average NFL player is probably 6'3", 235 lbs, and his job is to either move the football over the goal line OR prevent his opponent from doing the same. I'm not saying they cannot express an opinion, but the SJW's are trying to eradicate the masculinity out of the game and society at large. The League is being played for fools here, and that includes the owners. It was good to see that the fans at the Packers-Bears game were having none of it.
