Yes I see you doing this all over the thread italicizing the same words and using them slightly differently, I'm not sure what point you're trying to prove.
ADA predates DEI by a couple decades. Lots of people, including Republicans, support the ADA and support expanding its protections.
This is a pretty standard tactic of partisans when their pet issue becomes unpopular - take something unrelated, or at best tangentially related, and pretend it's related or that that's what they've been advocating for all along.
I don't care if you support the ADA or you don't. I don't care if you support DEI or you don't. But they're different, they've never been related, and any attempt by partisans on the left to lump them together is just trying to reframe the issue as "against DEI == against the ADA" because of course everyone on the right hates disabled people right?
Scroll up a couple lines from your link and take a look at the sponsor, who Republicans nominated to be President. So no, your partisan assertion is nonsense.
Are we to think that the Republican party of 1990 - of the Bushes and the Cheneys and the Romneys - is the same as the Republican party of 2025 that has driven them out of the org?
The ADA requires accommodation. E.g. a blind software developer should be given an interview that does not require sight. So a text-only description instead of a figure or sketch would be accomodation. It does not require specific levels of representation. It is not analogous to Meta's former "representation goals".
