> Worrying that kids may not be able to get into a decent school because they're not diverse enough seems like a a nice problem to have--parents of "diverse" children have much larger worries.

It only seems that way to you if you can't empathize with others. The OP makes a valid point. Any group that is caught in the crosshairs of discrimination will naturally be worried for their kids. It's not a "nice problem to have", as you put it, regardless of the group being targetted.

> Wouldn't that mean that based on the equality of outcomes, it doesn't matter what type of school OP's kids go to, and therefore no reason to worry.

Equality of outcomes? It's just a fact that some people excel at work/school (for various reasons) or that some people receive different pay (again, for various reasons). The point is that we shouldn't discriminate against things like sex, gender, and skin colour. That means I don't consider gender when I hire... but I also don't consider it when I fire, either.
