The notion that you cannot and ought not be discriminated against for your race, national origin, gender, etc, is a very fair and noble one, and ought to be the policy of all public and private sector entities, and how the law is enforced. Sadly, that's not what DEI has been for many years, and anyone making a claim to the contrary is not being an honest. DEI was wielded as a shield to be racist, sexist, or otherwise discriminatory towards groups that were unfairly labeled as "privileged" (particularly, but not exclusively, straight white males), and denying them opportunities based on these protected characteristics, so that a more "diverse" candidate, leaving merit aside, could take their place. The word "diverse" took on new meaning as simply "not white."
This was all done based on the assumption that because someone is, for example, a straight white male, they are inherently more powerful, better off, wealthy, etc, than a lesbian black woman. What this asinine theory of intersectionality fails to take into consideration, of course, is that one's protected characteristics are not the sole predictors of power or wealth. I'd much rather be a lesbian black woman than a straight white man if it meant I could be raised by a stable parent(s) with high income and go to a private school in Manhattan instead of being raised in rural Alabama to a parent addicted to drugs without two pennies to scratch together.
It is high time that, if it is to be implemented at all, both the public and private sector implement DEI in a manner that ensures equal and fair opportunity to all people, regardless of their protected characteristics, including those who have been labeled as "privileged" by moronic pseudo-intellectuals who know nothing of their circumstances but their skin color and their sex. Its sole purpose should be that, whether one is a straight white male, or a lesbian black woman, or anything in between, these characteristics are meaningless and the person is to be judged by "the content of their character."
