That's why I keep saying banning a word or making a world "not professional" doesn't do anything as long as people's though doesn't change. Like saying "don't say black, say african American" doesn't make them suddenly like them, they'll still be racist. Changing words will just make them use a new word to mean the same thing.
Yeah there might be emotional things about certain words and not wanting people to use it can be understandable. It might be a step is a direction if it's to be less humiliating or be inclusive. But just saying "don't use this word, use this word instead" will make the new word mean the same thing with same derogatory meaning if people use the new word derogatorily. Now DEI has become that new word, and instead of claiming the word back, owning it, people might go "don't say DEI" and come up with a completely new acronym while trying to "heal" from the past administration.
The leading theory over this seems to be they're trying to invalidate a bunch of international/national agreements about the gulf of Mexico because now "that doesn't exist", or is not about this gulf that has a different name so definitely not the one from agreement. And of course there's also things about doing everything at once and getting people distracted by these while sneaking in harmful policies.
