The nfl players are choosing to kneel because its televised and they can easily get their 15 minutes of fame with their show boating. I can guarantee most of those guys can care less about their communities, its all about self promotion. Any idiot can kneel, it takes no effort. They just want other people to think they are somehow politically and socially concious.
If they really, truly want to bring attention to their cause, they can go to communities on their own time, not the NFL’s time or the fans time, and raise awareness by talking to cops and members of the black community. That would take too much effort. They would rather kneel.
