Which part of DEI do you hate?

I don't see affirmative action as fundamentally bad. Applied correctly and not too heavy-handedly, the privileged will still have equal opportunity to enroll or get the job, per amount of effort they put in, etc. And even if it is a bit too strong, their privilege will most likely make up for it in other ways.

In practice though, it's highly susceptible to backfire effects and is usually on the wrong side of "an ounce of prevention is worth a pound of cure". You can't expect someone who grew up malnourished, undereducated and generally mistreated by society to suddenly bounce back and become a "model citizen" when they get a good job or scholarship, statistically speaking.

Affirmative action is just an attempt to counter the existing systemic bias against minorities and women. It doesn't bypass any requirements, it just makes it so that fewer hiring/accepting decisions are "just hire a white guy" because that is literally how many hiring decisions are made.

A white kid born to rich parents that can afford all the extra curriculars and who had personal tutors and was able to do an unpaid internship and has connections has an advantage on paper even without knowing the color of their skin. Affirmative action just means that someone who is far less likely to have those advantages but otherwise meets the minimum criteria gets a chance too.
