People can be against the corporatized and (as you stated) occasionally unfairly executed DEI policies that many companies used for years under the guise of “fixing historical discrimination” or affirmative action, while also being in strong support for the fundamental ideas of having a diverse and inclusive work environment.There was nothing inherently wrong about DEI until people started using it as a racist dog whistle. I am sure there are plenty of examples of companies or programs that did not fairly or effectively execute their policies, but equating its support with the people who want it wiped off the face of the earth is a little extreme. For example, I don't think there is anyone on this site that would admit lack of diversity is a big problem in Naval Aviation. With that said, no one who supports diversity effort in bringing more women and POC to the cockpit actually thinks the Naval Aviation enterprise would dismiss of merit or ability (obviously) altogether in order to achieve said goals. But back to your point, the term is cursed and ruined now, but as leaders we need to continue to value diversity, equity, and inclusion at all levels. It’s not an easy problem, but that doesn't mean it should be abandoned.
Sure, shitty racist people hurl the term DEI out at anything these days while talking completely out of their ass. We all know them, and we all want them to shut the fuck up. But let not act like there wasn’t shitty people across the isle who loved using the DEI cudgel to accost and ridicule those who committed the heinous act of…..being born a straight white man.
You don’t support and assist marginalized communities by tearing those ”in the majority” down. You do it by lifting the marginalized up, making them feel welcome, and pouring resources into these communities.
