You raise a good point about the Olympics...but what he's saying is not 'racism'. If you haven't noticed, we have a basketball culture that produces an overwhelming majority of players that are black minorities.
This culture is 'in your face', ego-centric, bling-bling, obnoxiously arrogant...and can be intimidating (in America only) because it has absorbed all of pop culture with it. Fighting it is like fighting American pop culture / media. It also seems to actually work as a mental advantage to the 'insiders'.
