I can see their logic in terms of the symbolism of the post.
The symbolism of the post apparently views white as a psuedo-pejorative, as they specifically mention his race as a problem.
This reeks of yesteryears feminism that defined a woman as only "woman enough" if she did X, Y, Z. Ironically.
Why is 'white' highlighted as a confounding issue in a college that is greater than 1:5 Asian -- Asian being a group that is socioeconomically better off than whites, has integrated in American society greater than any other minority, a group that's entire stereotypes are built on the same obnoxious "positive" stereotypes as white people -- good at math, plays music, expects kids to strive for success in a single generation, etc.
Following the simple minded and antiquated thinking going on here, I have to consider that an Asian Woman should not be in that post since surely she can't imagine the role of a diversity officer and is lesser equipped for said role than her Black sisters. Maybe the can all argue over who is the most diverse and female.
I find this line of thinking tiring and divisive.
“I thought he’d do a perfectly fine job, but it just felt inappropriate to have a white man there,
Clearly states that skills and content of character are not enough.
Even the NAACP allows white men to hold leadership positions. The only requirement? Convince your constituents, that despite your lack of like-experience as a black person, you can relate and promote goals adequately.
Your oncologist doesn't have to experienced cancer and your diversity officer shouldn't have to be a non-white female (gender, not sex).
These women have decided, and publicly stated, you are judged by your birthright. Hilarious.
