I am glad to see this, though I suspect that the NFL is just trend-following -- not much admirable about that.
The reason I am glad to see it is because the accusation of "racism" is usually used to ruin the lives of good people who understand the simple fact that racial separatism is a good thing for their race. And it is. It is not only good for your race, but it is good for the future of life in the Universe.
For without racial separation, evolution cannot take place. And without racial separation, life cannot advance to higher levels of consciousness.
