I continue not to understand this nonsense affectation, but not because I have another suggestion for "what white people should do" about anything. The only way this space becomes less culturally white is by becoming less demographically white. Whiteness is primarily displaced by nonwhite people. We are notoriously and necessarily incapable of solving these problems ourselves, especially from a position of power -- power which, thankfully, literally anyone can take for themselves. Displace us!!!
It's one thing when nonwhite people say something like that and I have zero reaction -- they deserve all the space they need to vent about the shit they're experiencing. But when it's constantly white people preaching to their neighbors to "stop being so racist", especially devoid of content or self-criticism, it stinks like cloutfarming whiteness-distancing horseshit.
