Racism or ethnocentrism is omnipresent. Blacks advocating for Blacks, Jews advocating for Jews and so on. But Whites advocating for Whites is the only one where racism or so called 'White Supremacy' is invoked.
It is known that the young of one race are more hostile/ skeptical of those from a different race so we overcome through learned behaviors.
If racism isn't applied in same regard, consistently for everyone, and we have different rules based on intersectionality and doctrines of oppressor/ oppressed which deviate from treating anyone by the content of their character then that is racist.
Endeavoring to have a functioning multi-racial society, transcending judgments of immutable characteristics and having a meritocratic society is where we have come from and is very delicate.
It's when 'outcomes' aren't 'as desired' or 'equal' when hackers try to manipulate. Different standards (not outcomes) for different peoples is institutionalized racism, and not in the direction you may think.
