Brother. Comrade. Friend. I assumed you're white because you think that racism is a thing in the past. That it's an icky, immoral thing for history textbooks and not something that anyone deals with today. I assume you're white because you defend white people in a scenario where they're privileged and that privilege shields them from the reality that others face. I assume you're white because when I give an example of what this experience is like for a non-white community member, you immediately center whiteness in your rebuke. You assume that speaking of the white experience as what it is is somehow racism.
Whiteness isn't some failing of race, it's a systemic knowledge gap where white people assume themselves the default race and they think they can easily project their experiences onto other communities. They don't know the struggles of other communities because they aren't forced to confront how racism impacts their experience. White privilege isn't something that gives them a leg up, it just means they don't have to grapple with racism in their day-to-day lives.
