Let's be real here, this is a rich, White couple who wants to rezone their school so it's more rich and more White because it's "what's best for their kids" while fucking over the low-income local students. 
Reading some of the articles (and really it was a quick glance, I don't have time for this bullshit): It seems like they're fighting to keep their local school than having to send their kids to a school a few blocks (or more) away. It makes sense in a selfish way. I don't think it's a "racism" thing like GAF is making it out to be. Just wanting to keep their kids local so they know where they are and don't have to travel.
The same thing happens with rezoning in rural areas. I don't think "classism/racism" is happening here, but Jason Jone's small quip
is pretty shitty. "Yeah, we're not being classist or racist! We're just wanting to keep our kids local!" isn't something to really crow about.
