For the record, "racism" is the attitude and belief that non-racial characteristics can be presumed about a person simply because of his race. For example:
Black people like to eat chicken and watermelon,
Asians are terrible drivers,
Indians (from the Subcontinent) are all good at math,
"White" people enjoy oppressing everybody else,
and so on.
It should be noted that a racist idea can be positive, neutral, or harmful.
"Blacks are better at basketball than 'whites'."
"Blacks have longer arms and legs relative to the length of their torso's."
"There are no world-class Asian sprinters because of the way they squat down as children; it fucks up their knees."
Accordingly, anyone can be "racist."
But that begs the question once asked by the honorable HRC, to wit, "At this point, what difference does it make?"
The DIFFERENCE is the impact of racism on the target group. If it results in more Asians being hired to STEM positions because the hiring executives assume they are best suited for those positions... If it results in Blacks being accepted to colleges and programs for which they are not technically qualified... If it results in a disproportionate number of "white" women being hired as actresses and models...
Could we therefore say that ALL RACISM IS BAD? The answer is not obvious.
How about a refined term, "Insidious Racism"? Racism that may or may not appear harmless, but proves to be harmful in practice.
And of course Racism without power is empty and fairly meaningless. The homeless Black person who hates "Whitey"? Who gives a shit? Until he assaults a random "white" person (or Asian), then it becomes an issue.
Racism is ubiquitous. It is everywhere, in all races, ethnicities, and societies. It will never be wiped out. So as a matter of public policy, one can only be concerned with demonstrable, harmful racism, in real time (not 200 years ago), which should be dealt with quickly and definitively.
And for the record, to infer racism from "inequality" is logical, moral, and political bullshit. The reasons for inequality go far beyond demographics.
