Because if they’re not white, they’re PoC. Racism against north east(?) Asian people is different from those in south Asia, or even, to an extent, south east Asia. What you say is true, but it is on a smaller scale, and does not excuse the blatant anti-blackness in our communities. I see SA people saying things against darker skinned people, and it’s not just because they’re not white, but because they’re darker skinned, and there’s a world of oppression set against Black people.
