aside from this being a heavy-handed socratic moment, i will play devil's advocate for a minute.
oppression can be measured by a) historic significance (for example, slavery of black people in the u.s. is an historically--and culturally, and economically--significant phase of life in the u.s.), b) preponderance of experience (for example, black people in the u.s. have to be particularly careful around police--especially non-black police), c) economic relevance (for example, redlining of neighborhoods by banks, redevelopment of poor districts, frequently of color, by cities, etc). another controversial criteria would be people's capacity to go somewhere else... does a somewhere else exist for a specific group where they are not looked down on, threatened, etc? how far away is it (both geographically and culturally)? prison rates are another common quantifier, as are death rates (how many people die as babies, teenagers, vs how many reach old age), and health markers of various other kinds: alcoholism, diabetes, etc.
other ways of measuring follow things like active political/cultural presence (young people of all ethnicities acting like the black people they see on rap videos, for example), or visibility in political matters (the grey panthers used to be a thing. so did the brown berets. there have been multiple identity based rebels over the years just of my life. there is an argument that those models--including the women's movement--were all based on black liberation struggles in the 60s, but it is not merely the strength and tenacity of black people that meant that their movement was addressed. wilderson, i believe, would be in line with the idea that it is the black/white paradigm of this culture that allows black people more visibility in both resistance and in subjugation.
so is it more oppressive to be told that your people are evil (black people), or that you can't exist because your people were all killed )like native americans), for example.
it is possible to take this oppression olympics thing as a provocation to do some important theoretical work that pulls apart POC as an umbrella term, as well as looking at other ways that people are systematically (and systemically) devalued, to look at how the differences are real and how negating those differences deepens the power of the state. maybe you could do some of that, human?
