Wow, OK, thanks, I always look young. But I'm not. I too taught college back in the mid nintes. But don't take the criticism as a personal attack. The idea is that most white Americans display a systemic racism unintentionally and I'm just revealing this systemic racism underneath the perhaps decent intent we have in communicating about race. After all, I don't think you are racist or on the right and get the impression you are open minded and perhaps "liberal" (a free thinker, open minded, etc.) as I am. Even whites open for dialogue who are the most sensitive of whites can unknowingly express systemic racism. I don't think you are personally racist and certainly give you the benefit of the doubt there. And I only wish you the best of luck.
