If you're disadvantaged because of your race, then it's racism.
It's important to be clear: the outcome is racist even when no individual is being racist. You can't be reductionist about this, you can't decompose the company into its individual employees and give any of them individually the blame for racist hiring outcomes. It's an emergent phenomenon: it is the company as a whole that is racist and the company as a whole that is at fault.
This is politically-correct/Marxist protelariat/bourgeoisie nonsense. The human race is composed of individuals, not "classes" at war with one another.
What qualities? You have said that no one there acts in a racist way. No "person of color" who applies for a job is treated unfairly. Thus no racism occurs.
You can only imagine racism there if you see the races as "classes" (i.e. in the sense of Marxist class warfare) and feel that each class (not the individuals within it) has a right to a "share" of the company (i.e. a quota of jobs -- regardless of whether anyone in a particular class ever actually applied for a job and was treated unfairly). I know this is what the leftist professors in schools of "grievance studies" are peddling, but they have tenure requirements to meet. What's your excuse?
