Black people are victims of white supremacy, that's a fact, Tariq isn't suggesting that people take comfort and do nothing about it, he preaches Black economic empowerment not "feel sorry because you're a victim", whites are dominant over all non whites in this system this doesn't mean that Black people are incapable of success, nor does Tariq suggest that at all. The purpose of the episode about the name calling that whites and others did after the fight was to demonstrate to confused Black people that this is who these people truly are and what they think of you, it's a teachable moment, it wasn't about "poor us, people call us names", but rather, stop dealing with these people and support your own.
If white supremacy didn't exist or was insignificant, people wouldn't be discussing it.
