Can Afro-Americans be racist?

What I found interesting in the around Adria Richards, was that the majority seemed to focus on a basic definition on racism. This made me rethink my previous assumptions. I want to discuss in (-:prog:-) if Afro-Americans can be truly racist to the majority conservative white population. I believe it would be a fallacy to think a Afro-American can be racist toward a white conservative male, seen in the light that the former does not belong to a majority and is thus not equally valued in terms of power and influence. What do you think (:prog:)

I doubt mitochondrial DNA will be much help. Because the virus has to get into the cell to find specific mitochondrial protein. If it cannot find it, it should not replicate and die in a nice way. That's quite some molecular machinery you have to build.
