So, I don't think this is about any of the racial groups, but more so about the fact that diversity advocates have latched onto a narrative of underrepresentation of minorities as the issue, which is basically asking for equality in outcomes (i.e. demographically proportionate representation), and Asian Americans (largely due to skilled immigration) do not fit this framing. Except for Asian Americans this is a narrative that works well for minorities, and also lets them push for affirmative action that may be necessary to correct past injustices.
