The thing about posting a bunch of hate about this is that it just feeds her ego further. Because whether a diversity hire or not, she "won" and people can be just written off as bitter detractors.

The best thing to do is just an emotionless "oh, good for you" because it shows that nobody gives a shit about her accomplishment and she's patting herself on the back for nothing. If you think about it, it's super pathetic, because she's held on to that for 20+ years.
