Every ideology is all flowers and rainbows until it gets put into practice.
There aren’t simple answers or one-size-fits-all solutions. Picking a representation metric for one demographic and pushing it up won’t fix things, even for that population. Many people are, at minimum, skeptical of DEI, and are inundated with clickbait news reinforcing their skepticism.
The people doing the real work understand all this and still show up every day trying to making things better for people.
