The Question
Eternal
Racism is defined as a power structure that allows one group to put a system in place where they use their race to direct discrimination against people of different race based on the belief that their own race is superior.
That's how racists who are too chickenshit and hypocritical to own their own racism define it.
Here's the real definition:
Racism is the appraisal of individuals based on their race, and either negative or positive treatment of those individuals on that criterion before any other.
That's the definition, full stop. You do that, you're a racist. Anybody can be (and most people to some degree are) racist.
The "definition" you threw up lets people get away with racism. That's a definition created by and used by racists to excuse their racism.
