Important point Westslope, additionally the supposed reason to take a knee is to protest the "inequality" in the U.S. today. 
This, of course, coming from Black players that make up 75% of the players in the league, and make millions of dollars a year!
I think they should start "equality" by giving me half of their millions net worth just to make us, you know, equal.  Then we should implement an affirmative action program that will require owners to only employ "others" until at least 50% of the players are non-Blacks.
Then we can go to the NBA were 11 out of 13 players on every team are Black.  This is a clear sign of discrimination and racism being perpetuated against "others" and must again have a affirmative action program mandated and a hiring freeze put in place until at least 7 out of 13 players in the NBA are others, (penalizing the teams by one player to cover past racist transgressions).  Lebron should give me half of his earnings too, so, ya know, that we are "equal".
