I see plenty of racial diversity. There are folks from India, China, Korea, Japan and many of the islands in the south Pacific where I work. And if you look closely at the so-called "white" folk, many come from all across Europe and Arabia. Are they represented equally? No. If anything, "white" people are underrepresented compared to their percentage of the population.
It's a mistake to talk about "racial diversity" when that's not really the problem. It just distracts us by framing it as a problem of white people discriminating against non-whites.
