This exemplifies why the provision is so bad. DEI is a term of art, not a specific thing. Everyone is proud of PyPI for standing up for whatever they think DEI means, but they don't define or explain it so it doesn't actually mean anything. Or rather it can mean anything at all. That's the danger to the organization.

What DEI does (among others) is if there's two candidates for the same opening with the same exact qualifications, the more marginalized will be hired. Before that, it wasn't a random choice of lottery, but who looked "more trustworthy" (white) or "more competent" (neurotypical). White nationalists want to undo not only this, but to go back the days when blacks (etc.) were actually discriminated against, because their feelings and memories of calling someone "working like a n****r" (context: slavery + blacks in the segregation era often had to work way more for way less).

Not necessarily. But your reaction is a good illustration of what the conservative narrative is when it comes to DEI.

DEI isn't about excluding a majority to promote a minority, but to make sure being part of a minority doesn't handicap someone.

But some people feels that it is in their right to exclude people they don't like, which can be understable when it comes to not recruit someone who stole from you previously, but in most case it is based on prejudices against specific minorities. And that's the main problem.

Those prejudices, most of the times based on misunderstandings, fear of the unknown, if not jealousy (antisemitism in Europe is often based on the idea that Jews perceived overall wealth is stolen from others).

Those prejudices greatly diminishes (or, as you wrote, "steals") their chance to be chosed for well paid work (if not work at all), and to be represented in media like videogames (because of knee jerk reaction like that game where you steal back artifacts from museum got).

DEI, when not exaggerated to the extremes, is beneficiary for everyone involved. Recruiters find talents they wouldn't have previously considered, people broadens their horizon by learning others culture, philosophy and history. Who in their right mind would refuse that, other that self-centered bigots?

In my case I'm glad of the diversity of people I meet at work. I don't care if they are black or white, gay or straight, male, female, or anything in between. They are competent and hardworking, that's the only metrics that should matters.
