I feel it is incumbent upon us to call out people who make racists remarks no matter what ethnic background they are. It doesn't make it okay that he questioned RGIII's fiance' choice or he should flaunt himself to be more black in societies eyes.
It's just ridiculous that he feels like he can make statements like that because he's black and others can't....no one should, we are all peoples of this globe that need to love one another and be accepting.
In the immortal words of MLK:
It is not the color of ones skin but the content of their character (paraphrased).
