Our pundit class is always behind on these types of things, but in 2016 an NFL player could begin a game by running to the center of the field and burning an American flag and most people wouldn't give a shit. Yes I'm exaggerating, somewhat, but even if people objected most people just wouldn't really care. Those who did care would find their feelings highly affected by the race of the player and the purpose of the protest. But, again, most people just wouldn't care. More important things to occupy our brain space.
Most of the people claiming to care about such things on your teevee don't care, either, they only "care" because they think they represent the America of their fantasies, or they "care" because it suits their politics to. They don't actually care in the sense of having an actual feeling about the topic.
