The numbers don't seem to matter: the idea that "black people are dropping like flies" and it's white people's fault because of slavery and the fact that most people in the US have been from Europe since its founding ("white privelige"); that idea is all that matters to those whose worldviews align with it.
There's this idea going around that the suffering of the poor is the fault of wealthy people, and the suffering of the poorest in-general group of people is more important than the suffering of poor people in general. From here you develop this hierarchy of suffering based not on individual experience but on categories of race, sex, gender, wealth, etc. (Intersectionalism).
Applied at the individual level, the idea that a person less fortunate in the circumstances of their birth has a more challenging life ahead of them makes sense. There's a lot more than that that goes into determining whether a person will lead a happy life; but in general one would expect more visible success in such an individual.
However, people are stupid. When you tell them: "hey, life is harder if you're poor, and if you get a poor education, and if your dad skips out on you, and if your older brother is in prison by the time you're in middle school". This makes sense to people, but they don't like nuance and subtlety and having to judge peopls as an individual: it's too much work; they want things quick and simple. Instead, they say to themselves: well, if this easily-identifiable group has it harder than this other easily-identifiable group (hint: it's the skin colour), then I'm just going to put everyone from the first group into the "victim" category, and everyone in the second group into the "priveliged" category.
And then we get shit like biased hiring practices, bestselling books about "white fragility" and "black pain", and we get schools teaching children that the act of being white is synonymous with murder. It's gross oversimplification. It's a disservice to the people who accept this way of thinking, and everyone they judge based on these categories.
