Depends on your definition of racist, hoaxie. According to what they are teaching us in college, you cannot be black and racist. You can be prejudice, yes, but not racist.
Now, this is all based on what they are teaching in my college today. Racism is a system of advantage based on race. AKA Prejudice plus power.
Based on the definition, according to the text, black people cannot be racist. They do not systematically benefit from racism.
That is what they are teaching in liberal colleges this very day. This came straight out of my textbook.
