It doesn't matter. Even the blacks that aren't ancestors of slaves are victims of uniquely white oppression and colonization.

Also, think of blacks as a group or even one tribe. They all want to celebrate the emancipation of their black tribal brothers, and they all ache from the enslavement of even a single nigger.

I wish whites were more like niggers in that being black is a big part of who they are. They see fellow blacks as their people and take pride in their racial accomplishments as a group.
