Not sure if you're missing it, but yeah, reverse racism is not a thing. The concept of racism is meaningful in the historical and societal context of systemic oppression. A black person saying "all white people are bad" is not feeding into and exploiting hundreds of years of prejudice stacked against an under-privileged group.
Edit: a black person in the US, different cultures are different contexts.
