We've done some pretty f'd up stuff to folks of color in the past.

One of the most notable examples is that of the Tuskegee study on untreated syphilis, where we denied effective treatment w/o informed consent.

PoC have higher infant mortality rates, and the myth that PoC have more tolerance to pain (and therefore require less anesthesia) is still quite prevalent.

It was bad enough that we had to actually produce a report on what is considered the "bare minimum", but even that has not been totally effective. (https://www.hhs.gov/ohrp/regulations-and-policy/belmont-repo...)
