Sir... in my world finding a successful black MMA fighter (an actual role model) is like finding a unicorn. Of course in a sport dominated by white people you wouldn't understand that now would you?
Actually I don't use color as a part of the equation. It seems to be your primary criteria and possibly only criteria. An athlete is either a role model or he isn't, you know it when you see it. Additionally unlike you I don't know the color count for MMA, but I do watch a lot of sports live and on tv and I have to say at a glance there appear to be many Black athletes throughout sports.
