they very well might have been evaluated based entirely on their abilities alone.

A toxic element of DEI is that now they have to always wonder (as does everyone else) if it was done because of their skin color/gender/race, regardless of what their mentor says. Because it very well may be true as well.

Just like the justice system. People should be assumed innocent until proven guilty. DEI and more broadly CRT are toxic because minorities, like all humans have faults and these ideas promote minorities to assume discrimination instead of faults. Therefore not helping these individuals improve their faults. This also promotes division and hatred in society. Overall net negative.

to be fair, I don't think yelling at someone for their flaws is very effective at fixing them.

My reasoning can be summed up as "look at prison recidivism vs Skinner's work on positive reinforcement".
