It's entirely possible to care about more than one group of people at a time, but pretending like the "real" hardship is on poor whites with the implication that other people are whining is unbelievably offensive and also out of alignment with facts. If you want to join the Penguin in that belief, be my guest, but it's nuts and also contributes to continued inequality.
"A poor white child who has to eat at a soup kitchen has significant disadvantages and one might even say economic oppression. And there are still things that they will never face in this world that even the richest Black person routinely has to contend with. That's what privilege is speaking to. The fact that you simply refuse to understand or acknowledge that is a part of that oppression."
