I also feel the same about calling out any form of bullying, belittling or unjustified prejudice.
On this we can agree.
It simply tries to absolve in any instance that the perpetrator bears any blame
I see the statement to which you objected as being a relevant opinion on racism. It calls out the "Pity me, I'm a victim" mentality, which by the way is NOT limited to racism. It can also be about sexism, genderism, or any ethnic-ism. To the extent that a person claiming to be the victim of racism is in fact a victim of self-inflicted bad behavior leading to a condemnation or other bad result, claims of racism - like ANY OTHER ACCUSATION - need careful analysis and verification.
Want examples?
- The recent "Haitians eating pets" quote, for example, has now been traced to a person whose anger over a sudden Haitian influx in her area led her to fabricate that claim. She hated change and her neighborhood was undergoing change.
- In WW2, Hitler's claims against the Jewish people (and gays and handicapped people and 7th Day Adventists and the Romany people) were ALL a form of scapegoating.
- Modern-day claims that gays want to "groom" children to become gay have long ago been shown to be a fabrication.
The latest trend towards DEI is an example of applied insanity (though I cannot rule a bit of natural issues as well). Diversity? Not a problem, I'm all for it. Inclusion? Totally fine with me. Equity? Depends on what you mean by it. It CAN become a crock of, as you put it,

, because it should be Equity of Opportunity, not Equity of Result like Ms. Harris seems to want. To put it simply, if I refuse to hire you because you cannot do the job I want done, the color of your skin doesn't matter. Your gender doesn't matter. Your nationality doesn't matter. Your religion doesn't matter. The only question that EVER should matter is "Can you do the job I need done?" If you don't prepare yourself in a way to be able to answer that question "Yes" then don't expect to work for me. I'm not the headmaster of a school for training. My economics and business model can't afford to support people who can't further my business needs. (Though some such places DO exist, and good for them!)
The question is, do you see my stance on DEI to be racist? Or simply motivated by the harsh reality of economics? This will decide whether YOU are a racist or not. Because if you consider that economics is a well-studied discipline, you would realize that it doesn't actually contain ANY theoretical references to the abilities or inabilities of the various ethnicities. It only talks about abilities of individuals or amorphous groups as applied to problems of a hypothetical or actual workforce.
