Respectfully, Black people have always been aware that they're marginalized. At best, they're interacting with a system set up by and for the benefit of males with white skin. They can hope that this system only sees them as "other" and does its best.
At worst, that system openly attacks them, rejects them as people, metes out punishment when a verbal acknowledgement would have been afforded the white man, or puts their lives at risk.
The system operates transparently for me because it was designed for me. It recognizes me as "normal" and proceeds accordingly. It's very easy, then, for me to consider the system as "normal" and wonder why someone not like me can't simply accept the system as it is.
Black football players are using their position as popular, accepted individuals to give a voice to the notion that the system can be changed by adding Black perspectives. By doing so, we could, therefore, grow the system. The system gets stronger and more diverse.
I'm glad we were able to, for the moment, reach an accord on "The Eyes". There is no call for blind acceptance of any one side of these issues. However, the danger is that those inside the system reject outright the existence of the issues themselves and refuse the debate.
