To understand what "diversity" truly means in a modern context, simply ask yourself this question: have you ever heard anyone claim that the NBA is not diverse enough?
I kind of pieced something together recently that makes me feel sick to my stomach. Diversity only matters in white majority areas or white countries. Too many white people anywhere is a bad thing apparently. Nobody in Japan is losing out on a university job for being Asian.
Top universities also discriminate against East Asians in the admissions process because of their high performance. Basically, DEI is discrimination against high performing races (except Jews, perhaps).
