What a piece! Just for information, Super Mr. C, also known as "Steadfast Mister," is a Philosophy professor. He generally teaches Moral and Social Problems. According to him, when he's teaching Racism as a facet of moral and social problems, you can give white students tons of evidence, with which they will agree. However, even given scholarship and documentation, they can still not bring themselves to admit that they have enjoyed the benefits of systemic racism. It's true in "theory," but it couldn't possibly apply to their lives.
At first, they are awed by his knowledge. Second, they wonder why he cares so much about "other" people. Last, he's a traitor to his race because he wants them to admit that racism doesn't just dwell on the page and in statistics. As for needing a white person to talk to other whites, "Steadfast Mister" is white, but he'll tell you that if people don't want to know, then they don't want to know, no matter who tells them.
