So, intra-POC prejudice and racism exists. It is a thing, an actual thing. It is pernicious, in the U.S./Canada it is often a symptom of white supremacy where we all fight according to the rules set by whiteness to judge each other and find each other wanting.
This occurs despite a long history of inter-POC cooperation, where in the living memory of our elders, Asian groups participated and helped in the Black Panther Party's activities, and Jews testify how black soldiers can to rescue them (and thus, how they knew the soldiers were not Nazis), and many other such histories which I can't recall at the moment. All histories usually unspoken of, to the point where it is such a big fucking surprise to discover they exist. All pointing to how our intra-POC conflicts are really very counter-productive. All proving how short our communities' memories are, because these stories have been so covered up into non-existence, so we'll believe anything mainstream media tells us about each other.
There is a Global Hierarchy of Race, which follows skin tones and assimilation into Western standards of modernity. In this hierarchy, darker-skinned peoples suffer more than lighter-skinned ones. In this hierarchy, my light skin and Westernized background count me as acceptable to whiteness, as "the other white meat." If anyone followed the Tiger Mother kerfuffle, you would have an inkling of how assimilation into the white American middle-class lifestyle was, and still is, so incredibly prioritized, so the younger generation can have "a better life".... a white life.
This system of white supremacy requires something to measure up against for superiority. And as Lance Selfa has demonstrated, whiteness needs to be measured against blackness. This has been eloquently articulated over, and over, and over, by such writers as Booker T. Washington, Frederick Douglass, Malcolm X, Martin Luther King Jr., bell hooks, Audre Lordre, Franz Fanon. Blackness is a depth, blackness is the dark, blackness is the bad, blackness is the inferior, blackness is where you do not want to be, blackness is that which we do not want to inhabit.... so on and on states a variety of media, a variety of sources.
And we internalize this as a truth. As little children. And we see it repeated everywhere. In the last week alone, I've seen the following on Tumblr:
