HN, like the American tech industry in general, is almost certainly more diverse than the Stanford administration and faculty. Moreover, diversity in HN is organic. Folks on here may happen to be Laotian American (or even Laotian—HN is international). Nobody selected them for inclusion in the community.
By contrast, diversity at Stanford, especially among faculty, is carefully curated by the overwhelmingly white faculty. Your average immigrant from a former colony may not care about eliminating “colonial language.” But the white Stanford faculty wouldn’t hire those immigrants into the cultural studies department of the university. You’re much more likely to get a job at Stanford by writing papers on how colonial terms “cause harm.”
The faculty system and widespread use of race and nationality conscious hiring gives white people at elite universities tremendous power. There’s few other organizations where the white leadership gets to hand pick any minority representation based on its own ideological priors.
