To be clear, do you think race-based diversity hiring is good? I can agree that having good role models and educational opportunities is important but I'm not so sure race-aware hiring is a good thing, for the reasons stated by OP and others.

At what point do you think DEI should stop? Is there any metric or threshold at which these programs/events should end? One of the biggest issues for me is that these measures are either argued as good because "diversity is intrinsically good" or because "we are righting historical wrongs", meaning reparations. While one could argue for or against either of these justifications, it would seem that the former would terminate once some ideal demographic composition is achieved, while the latter would end once some calculated total sum of restitution is reached. To me, these details are very important, since race-based hiring is an intrinsically bad thing that should be avoided. After all, it is part of the reason people of color got so screwed over in the 20th century in the first place.
