"Proportionally," white players and owners and coaches have led the way in many vile and illicit things throughout the league's history. If you're against something in particular, you can fight it across the board instead of taking counts.
Don't like professionally-paid athletes doing crimes? Fight against all of it, and don't wait for the league to integrate to worry about proportions. I'm not holding Ted Nugent responsible for "dealing with" the scofflaws above.
Don't like crime in general? Fight against all of it, whether the criminal is looting a store, or assaulting people in the street, or striking his significant other, or shielding his or her crimes with a badge.
We need not wait until a specific demographic that irks us is engaging in it, "proportionally" or otherwise, to suddenly have a problem with it.
Law-abiding persons of color are in communities fighting crimes (white and blue collar) and keeping more from happening everywhere. This includes the many, many more upstanding persons of color currently in the NFL. And, yes, even entertainers like the one mentioned here.
The fact that many members of civil society have long preferred to marginalize than to fight injustice, because color, are why agitator groups like Black Panthers (the miniscule new and the glorified old) have formed in the first place. #AllLivesCantMatter if BL don't M. BLM today, and Black Panthers then, are reminders that, unfortunately, they have not. Peaceful, muted, displays are nice, too. But sometimes, as we all know here, you have to ACT UP!, if you will, to get the attention you need for meaningful change.
We never get to statements like "Believe in Love" (thank you Coldplay and company) if we begin with a conceptual premise that suggests certain races are statistically less capable of it.
