As I previously posted, all that needs to be done to stop this is take away the stage these clowns now have. When the Anthem is played the cameras should all be on the flag and not on the field or the players.
Trust me, this will all stop within a couple of weeks when it is obvious no one is seeing them except the fans in the park and we know that the YUUUGE majority are NOT with them as is evidenced by the boo’s.
It is too late for that. The time to have done that was when it was just Kaepernick. If they show the crowd and you hear them booing, you will know the BLM contingent is at work. If they eliminate the anthem altogether, you'll know it was because of lack of respect and will still be pissed off. I frankly think the NFL has let it get out of hand and have probably lost fans that will never return.
