There were many unsettling historical accounts of which I took note, including:
~Native American's being coerced to give up children for adoption after the closure of Native American boarding schools
~Dr. Sim's torture of a slave women with multiple painful forced vaginal exams, refusing to administer anesthesia
~Stealth sterilization of Black and Puerto Rican women
For me, the most disturbing historical fact was that the treatment of Mexicans at the US-Mexico borders inspired the Nazis. Specifically, border crossers' heads were shaved and they were treated with chemicals including gasoline, kerosene, and DDT. Their belongings were treated with Zyklon B (cyanide preparation). The Nazi's took this a step further to do mass murder.
I think it is clear that these activities have had impacts on society today. You can see the mistreatment of Native Americans at Standing Rock, Black women have higher maternal death rates in childbirth, and in as early as 2016 25% of medical residents although that black skin was thicker than white skin, and many of those residents also provided inferior treatments due to thinking that black people felt less pain than white people.
