It's not never ending. We're very critical of the racism and sexism in medical research. And the younger generations of doctors are far more aware of it.

We used to butcher women in radical mastectomy surgeries and we don't do that anymore. We used to do medical experiments on black Americans without telling them and we don't do that anymore. For everything that you can point to as a current problem, I can point to another thing that used to be a problem and now has been corrected.

And still none of that has anything to do with physics, chemistry, materials science, geology, oceanography. You can't just say "racism impacts some sciences therefore we shouldn't do science at all"
