I think the term anti-racist has new meaning for me now because it also implies anti the term "race" and its implications. I'm still learning and could be wrong about that, but learning about the history of "race" and how the term morphed into ways that would help the racist society makes me look at "anti-racist" differently. This section also reminded me of the book Weapons of Math Destruction which has chapters on how algorithms impact court sentencing, bails, and other matters related to the justice system and how race enters into that data. Knowing the history of the term makes that seem even more unjust than when I didn't know the history of the term and still thought those algorithms were unjust.
I was also very disheartened to learn that the town I grew up in, Puyallup, WA, was home to Camp Harmony. Of course, I never learned that. It's not totally surprising. I learned some years ago that towns that had lynchings (one in particular whose name I can't recall) have gone back to the newspapers in their libraries and scrubbed references to them. So I would imagine towns in general would want to erase their connections to an embarrassing and shameful past.
I also found it shocking that up to the 1990s, there were still unethical experiments being conducted--the one on the young black boys. I recently participated in the training: Protecting Human Research Participants, NIH Office of Extramural Research. I foolishly imagined that all such unethical experiments were relegated to the distant past.
I really wish everyone could know these histories.
