People of color experience more discrimination and a greater chance of negative outcomes in the U.S. healthcare industry. This is well known among affected communities, and there is a large body of knowledge around the subject. It stands to reason that a more diverse workforce in said industry would mitigate that, at least partially.
So, I encourage you to at least entertain the notion before you cover your ears. The macro view of general outcomes in a system is different than an individual micro-level choice. Of course any individual hire for a skilled role should be merit-based first and foremost. That being true doesn't invalidate the entire discussion around the importance of diversity in organizations, but you'd very much like it to, I can tell.
