As someone who has no dog in this fight (and fully aware that an insult, and not an answer awaits me), are you saying no black person has ever, in the history of the medical profession, been saved by a white doctor? I know it’s an absolutist question, but yours is an absolutist point as well, when you say that every single black person should let every single white person die.
Because by that same logic, every single white person should also let every single black person die.
What you are advocating is segregation, and again, as a non-American I would probably benefit from having America crumble. But would that solve anything?
