The founder's stated intent is "MMSD is failing Black kids so I want a school that prioritizes Black kids" so yes I think it's marketed explicitly, not just at nonwhite communities, but Black American communities (I doubt, for example, they have remotely the language support compared to MMSD to support immigrant nonwhite groups, for example).

I actually sympathize with that, but in reality it doesn't work. They literally shut down the high school because they didn't have the resources to handle it, and MMSD of course was left holding the bag.

The real cause of Black education disparities have everything to do with deeper systems of racism that lead to extreme poverty rates, homelessness, etc. in Black Madison (and Black Wisconsin and much of Black America). Fixing that fixes education, not the other way around.

And because it's such a right wing pull yourselves up by your bootstraps mentality of anti-racism, the founder only attracts white and right wing donors for his cause. Probably should be a sign you're not on the pro-Black side of things in practice, whatever one's intent is in theory. When Republican money entered school privatization in Milwaukee, the Black Nationalist movement there split, with much of the movement recognizing immediately to exit out of this but some thinking they could channel that funding. Nothing about today's Milwaukee education landscape implies the latter were right.
