It might help to speak of the specific alternatives created as a response to DEI. Would you care to share?
I believe the set of beliefs associated most often with DEI are weakest with no opposition at all. I believe a lot of it is reactionary. This is why it needs huge media events where people can be outraged. But as far as ideas goes that would be general humanism like color blindness, freedom of speech and expression, freedom of association, guilty until proven innocent, equality instead of equity (although a balance h…
My claim is that the values you mentioned(free speech &c.) are derivatives of enlightenment thought whose epistemological basis is objective reality. This appears tautologically true for true-believers within objective reality.
The DEI values are derived from an internal contradiction within objective reality which is something like, "How can X,Y,and Z bad things exist when people can [supposedly] embody ?" That's the contradiction I'm referring to within the symbolic universe of objective reality. This contradiction creates cognitive dissonance that is typically either resolved through individual failings (individualism being another value) or in the case of the avant-garde, substituting the whole or parts of objective reality with an alternative one ie: the subjective one.
The big hurdle here seems to be understanding objective reality as itself a totalizing and reified instantiation of a particular symbolic universe. It's something that's difficult to explain through text, but a glancing shot might be to examine the contradiction at the horizon of objective reality, namely that the displacement of a subjective reality by objective reality's totalizing nature precludes the values that objective reality contains, specifically "the individual's freedom to choose one's reality." In a universe where individuals are free to choose anything, not being able to choose subjective reality feels like the universe singing a version of Meatloaf's ballad on repeat[1].
I can't help but point out that the values you've mentioned (to me) aren't a response to DEI, but what DEI is responding to. The way I know this is that they predate DEI. Values that are a response to DEI cannot predate DEI.
