Bureaucratic classification, not conduct, determines who mass murder targets.

Evidence

Decent Germans were forbidden to have their own decent Jews — decent because “their own”: the next-door neighbors, caring doctors, or friendly shopkeepers. Up to six million Jews were murdered wholesale not for what any of them had done but for how they had all been classified - just like, quite recently, in another hour of ultimate triumph of all-defining, all-classifying, modern bureaucracy, the armed gangs of Hutus and Tutsis of Rwanda set off their victims from the others of the same appearance, language, and religion as their killers, but meant to kill rather than be killed, simply according to the entries in their passports. — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 424

Categorization

• XREF: Parallels identity-based sorting as bureaucratic racialization; Rwandan passport classification evokes the same abstraction mechanism as Nazi category assignment.
• CANDY: The detail — Rwandan killers sorted victims from people who looked and spoke exactly like themselves purely by passport entries — is a striking elevator-conversation fact about how thin the line between victim and killer identity can be.
• corroborated: 2 independent passages support this claim — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 424
