“Racism against white people” doesn’t exist and never has. Racism only goes in one direction. Racism has always been a system that benefits / privileges / makes profits for white people. White supremacy is the underlying structural foundation of our entire society.
The closer to black a person is perceived to be, the more they’re dehumanized and viewed & treated as a “dangerous criminal” and “lazy”. This is on an institutionalized, systemic level.
Race is a social construct that white people invented to justify maintaining the system of slavery that privileged them and made profits / wealth for them.
