But if it was part of "family lore" rather than a known and named relative, then the injustice had disappeared into history rather than being something still weighing down on Warren. She should be ashamed of profiting from her ancestors' suffering for claiming that 1/32 relation should help her get a job at Harvard.
Injustices don't just disappear ~ even if you don't know about them some aspect of your current circumstances depends on them having happened.
Br'r(ess) Warren is a hard core member of the 1%, has a doctorate, works at Harvard, etc., etc. If she'd been a Shinancock Indian she'd had to raise ducks for a living and shovel day old bread out of the back of a pickup truck all the time.
See the difference?
