If a program treats people equally, that's a good thing. If you want equal outcomes (regardless of many very real factors), that by definition will require unequal treatment.
But related.
I was at a museum that had a full-sized submarine on display. There was a touchable model and audio description for blind people.
Equal, as much as possible - a Braille variant of a novel, for example, provides a fairly equal experience. Equitable, when perfect equal results are not possible. You can't fix a person's severed optic nerve, but you can certainly attempt to give them fair access to things.
As with "negro" and "colored", the new positive term eventually became a slur via concerted efforts from its opponents. ("DEI mayor": https://www.npr.org/2024/04/04/1242294070/baltimore-key-brid...)
Affirmative Action was from Executive Order 11246 (1965) -- concurrent with and part of the same movement as civil rights legislation -- applying to federal contracting; it largely spread to large organizations that weren't direct federal contractors through subcontracting relationships and through state governments adopting similar requirements in their contracting.
They're absolutely in the same category.
A lot of the culture war entities which now dominate the GOP did so (obviously, with different language, as "woke" and "DEI" weren't the current generic epithets for things the Right doesn't like) at the time, but (1) were mollified in some cases with special exclusions, like religious schools being excluded from the definition of covered public accommodations, and (2) otherwise were less politically powerful within the party.
Equal is giving everyone a printout.
Equity is giving the blind student a Braille version.
The latter is an attempt at providing equal access to the contents to those with different needs, so that they may learn equitably.
(The alternative term JEDI might argue that this is the just result.)
Equity would be mandating that blind students pass at the same rate as sighted students regardless of their scores.
Equal outcomes for all is not equity - it is inequitable for a deliberately lazy person to succeed when a hard working person does not, just because of something they were born with.
Giving every student the same printed packet is equal treatment, but unjust and inequitable to the blind student.

> Social equity within a society is different from social equality based on formal equality of opportunity. For example, person A may have no difficulty walking, person B may be able to walk but have difficulties with stairs, while person C may be unable to walk at all. Social equality would be treating each of those three people in the same way (by providing each with the same aids, or none), whereas social equity pursues the aim of making them equally capable of traversing public spaces by themselves (e.g. by installing lifts next to staircases and providing person C with a wheelchair).
