I think it's important to distinguish between diversity, equity, and inclusion as CONCEPTS and DEI as an organization and initiative.
It is possible to be pro- diversity, equity, and inclusion and be opposed to mismanaged efforts in DEI as a PROGRAM.
This post assumes that DEI as a government initiative is working perfectly and has no downsides, presenting it in a way that closes it off to criticism.
Does every system have to be perfect? Of course not. It's better to have a system pushing for good that's imperfect than none at all, but framing it like this is gaslighting and hurts discussion on both sides.
