Well there are two things here. Just generally, diversity and equal opportunity are not zero sum games. I don't have to lose for another minority to gain. The goal is we all win. This so called "counter argument" misses the mark and in my opinion sort of exposes one of the issues with what might be labeled the "conservative" perspective on affirmative action and related issues.
But to some extent there is a conundrum with white, elite "privileged" citizens lamenting the problems of blacks and hispanics and minorities while they listen to NPR in their BMW on their way to Yoga. I mean yeah that is sort of hypocritical if you literally do nothing other than complain. But at least recognizing that, internalizing it, making any adjustment in how you act at all is a positive step. What's the alternative? If you can't just fix it then do nothing? No.
Getting more granular: there is a difference between outright charity ("giving" someone your job) and working to change the system so others have equal opportunity, or equal rewards for similar effort. I.e., at your next promotion, if you advocated for more diverse hiring practices and promotional efforts, and then you resent the fact that a (equally or better qualified) black woman took your promotion, then yeah you are a hypocrite. Not getting a promotion sucks but if you are in favor of diversity and you know the foundational roots of affirmative action and so on and so forth, in some part of your brain you should be satisfied with that result. I.e., "the system works!"
But you're not a hypocrite if you don't just say "OK here take it." You're not doing anyone any real favors then. That's not changing the system.
