Framing your competition as diversity hires (and contemplating the outsized concern that they have on your life) says more about than you think. You're the bottom of the barrel at what you do. "Diversity hires" don't compete at a high level.
I for one know that if my competition wins, whether they are a minority or not, they do it on skill. I've elevated myself out of the concerns of competing with diversity hires, because I'm great at what I do. Level up.
