Kap kneeled because Nate Boyer recommended it to him. Initially, Kap chose to sit on the bench during the anthem and nobody gave a fuck. Nate Boyer who is a former player and a veteran, told Kap that kneeling is something that service members and athletes do during ceremonial stuff and that it would be viewed as less controversial than sitting.
Alsp, Kap explained why he kneeled and it doesn't need to be explained further.
My point is that, niggas are getting exhausted with the symbolic gestures. We can't even say Stay Woke after Kendrick's performance because the word woke has been hijacked.
So, how should we react when we are fed even more symbolic gestures even when they are on the biggest stage in the world?
