No racism is not a 2 way street. Racism involves a power dynamic, racism is a system of institutional, systemic oppression, and in order to be racist, you need both the prejudice plus the power to affect people. By that definition, PoC (people of color) can’t be racist, because they don’t have any reinforcement from that institutionalized power. Prejudice on the other hand is a different matter, and we all have our prejudices, and if you are too much of a dummy to see how being a young black man in the south in the 60's can leave you with certain prejudices, then there's really nothing else to say to you.
