At the heart of it is the notion of equality - that two equal candidates get a fair shake at a promotion/role regardless of race. And pointing out that Asians (or whoever) are underrepresented does NOT prove they don't get a "fair shake". It's also possible they are getting a fair shake and coming up short, or choosing not to be shaken. More evidence is needed. The over-representation of Asians in white collar professions is used as a bludgeon with which to attack other minorities... No one is "attacking other minorities". Asians are brought up to refute the "mirrortocracy" hypothesis: white gatekeepers in the industry will prevent entry by people different from them. Describing that as an "attack" is silly.
