The thing is... if white people have experienced racism/racial prejudice, that should make them more empathetic to the experience of people of colour. But based on the first few pages, it does not: it is just being used as a statement to ignore/belittle or compete with (with concomitant hostile notions of defeating) black experience.
If you are not using your (apparently) equivalent experiences to empathise and mobilise in solidarity, then you have learned nothing.
For example, I cannot know what it is to be a person of colour. However, as a woman, I can see some similarities between the manifestations of misogyny and racism, because both are institutional and structural in nature, as well as insidiously embedded in casual language and socialised behaviours. They are not the same, and white women have all kinds of privilege, but it is a great starting point for understanding and bringing nuance to that understanding that does not rely on people of colour’s emotional or intellectual labour in educating white people. From empathy comes solidarity, from solidarity comes change.
Sometimes, comparisons are effective if simplistic. I got elderly white people to understand the complexities of the n word by comparing it to the c word. Having grown up with children’s books with dogs named that offensive word, they were wilfully resisting the idea that the n word was offensive. Although they agreed it was socially unacceptable to use it, they kept complaining they didn’t understand why and that people are too sensitive these days. So I started using the c word With them, because i personally don’t have an issue with using the c word (won’t go into a spiel about why, unless people would like me to!) but knew that they did. It made them rethink their ignorant claim that “the n word is just a word and people shouldn’t be offended by it”. I recommend this tactic with any wilfully ignorant elderly white person. It really made them understand it at last, when all my attempts to explain racialised discourse and the history of aggression and oppression associated with the word had failed.
