While I cannot speak to this case (and I'm somewhat skeptical being that its published in the form on a WSJ op-ed), I do think that in general terms the DEI Raj on campuses is just another way to increase the power of the administration over the faculty and raise the cost of a college education yet further.
As someone who is generally left, I'm used to the scolds being on the right, now they seem to be in my tent too, and I'm a bit flummoxed on how to make them either moderate or leave - overt actions to do so are often met with a virtual firing squad of people who I otherwise agree with 75-80%.
In the end, I think the new racialism (racial discrimination is at the root of all problems) distracts from the larger problem of poverty, which is so intertwined with racism that you cant begin to tackle the unsolved problems racism without making substantial progress on solving poverty first.
