You have just suggested that when faced with a more diverse range of applicants, white men are more likely not to get a job. Isn’t that rather a self own?
DEI does not (and cannot legally) exclude anyone from being considered for a position. Outside of some very specific exclusions in the law, you can’t specify the race or gender for a position. The only barrier put in front of white men being considered alongside diverse candidates is whether he is the most qualified for the job. But don’t worry, studies show that even where the pool is more diverse, because it is largely white men doing the hiring, bias (unconscious or otherwise) still means they are more likely to be hired.
I have no problem with anyone who really disagrees with DEI. That’s a position to take, it’s an opinion I disagree with but everyone can have it. But what I see most often is people, like you, who don’t actually understand what it is, how it works, and why it is deemed necessary. That appears (to me) to be quite a racist/sexist take on it as it looks like people are only against it because it benefits minorities and women.
