There’s two kinds of racism - systemic, or institutional, racism, and colloquial individual racism.
Of course anyone can be individually racist. But institutionally, no. The American institutions and systems have always been white-focused, black people simply do not have the power to be institutionally racist.
I mean, has there ever been any anti-white law ever written in the US? No, because it’s not possible. The institution which makes, and enforces, the law is itself white.
