A bunch of pro-diversity people see white people do well and get successful. They see the same in Asians. They see the opposite for black and latino. They conclude "we must give black and latino preferential treatment to catch up". It is a bit more elaborate, but not much more than that.

>All Asians?

Yes. Despite their fronts, diversity initiatives don't look much further beyond sex, gender and skin color. You're already one level deeper than most of these politics go.
