One way to interpret that tweet is that it's important for patients of the same race, who live in a society that has historically, and currently, discriminated against them, to be able to commiserate, or even to be able to see that progress is being made. Another way to interpret that tweet is that the patient now no longer has to worry about a racist piece of **** who only got his career because of his privileged upbringing performing an operation on him that might've actually helped. Tweets like this both illustrate progress and the lack thereof. ANd I think you know it. However, you've convinced yourself there's only one interpretation, and any other one represents some sort of close-minded POV. It's the pot calling the kettle black.
