What is the functional difference between this and being committed to becoming non-racist?
In some spaces that I see, people do try to become anti-racist, which as a practical matter means that they become racially bigoted against people who aren't traditionally disadvantaged minorities.
For example, I've seen DEI training materials from a major tech company lauding blatant Title VII discrimination on the basis of sex and race as the right response to a case of possible implicit bias and/or structural racism. (If you swapped race and gender, you'd have had almost exactly the "bad, report this!" example from another part of the training.)
So I think an attitude of anti-racism doesn't necessarily provide the right cognitive framework as opposed to an attitude of savvy non-racism.
