The only thing these protesters are to do is hurt the NFL and the NFL fans. The NFL is going to lose viewers and merchandise sales while the NFL supporters are going to lost a relaxing national past time because some spoiled racists decided to disrespect the flag and the country it stands for. By supporting these radical racists the NFL has made a serious business blunder, but they are the ones who will have to live with it. 
As for protesters nothing will come for their actions because their demands are for other to change while they continue to do the same. The same 70% of black births to single moms, the same black on black murders, the same gangsta attitude and the victim mentality indoctrination.
