I'm skeptical of such Manichean pronouncements entirely. On one side the great hosts of racism, sexism, and oppression gather. On the other, the forces of wisdom and freedom.
It isn't realistic.
How many disagreements have their been over simply the definition of "racism?"
"Black people cannot be racist. Racism, is not bigotry, but bigotry in addition to social privilege."
This definition causes near endless arguments across America. For many, racism is negative action against another for their race. For others, there is necissarily a component of large scale power imbalances.
Thus, I've heard it said, black people cannot be racist, even against other minorities, since they face the most oppression. This is true, given a definition of racist that looks through a wide lense of "privilege" and advantage at a national, or transnational level.
At the same time, I can see why this doesn't fit with personal experience. The word racist has connotations of a greater than average sin. To be racist, is to be sinful on a deep level.
For my own experience: I went to school in one of the poorest and most violent cities in the US. Hispanics were the largest demographic, followed by African Americans. Whites made up what I would guess was at least 15% of the population, although when I check now it's less than 10%, making the district's schools segregated by most datasets definitions. The city's demographics are not so segregated, but the median age of White and Hispanic populations differs by a full 23 years.
The ethnic demographic subjected to the most ostentatious bullying were Asians. This included frequent racist mocking, up to serious random beatings that sent high schoolers to the hospital, and
resulted.in permanent brain injury.
Later in life I've heard the theory that Asians can be racist to African Americans, but African Americans cannot be racist to Asians Americans. The differences in privilege make equal acts unequal.
Whatever merits this argument might have, I doubt it will do anything to stem communal violence. If anything, it seems designed to be a wedge to perpetuate it.
The same question comes up in the question of Zimbabwe. Is the communal violence there racist?
Making definitions of racism correspond to broad, changeable ethnic hierarchies world wide seems to me to make for more fights over definitions, and less dialogue.
At it's worst, you end up with extremely warped ideas of history where "White" rich males have dictated all things, from time immorial, and all other peoples lack agency.
Why did Mossadegh face a coup? Because a single white man with $50,000 cash and a phone line willed it. Why did Pinochet lead his coup? Because he was told he would not be punished by US State Department employees. This is incredibly reductive reasoning that remains popular and seems racist in its own way.
