BREAKING: Unbelievably trivial story somehow becomes national news

From the Washington Post:

Florida parents upset by Michelangelo’s ‘David’ force out principal

This story is all over the place. Why? A tiny charter school in Tallahassee fired its principal over some dumb thing. How does this become widespread national news?

For what it's worth, the Post's headline is typical even though the chair of the school's board says that David was only one among many issues involved in the firing. Furthermore, he says, the issue wasn't even with the sculpture itself:

We don’t have any problem showing David. You have to tell the parents ahead of time, and they can decide whether it is appropriate for their child to see it....No one has a problem with David. It’s not about David.

In previous years the school notified parents about their plans for teaching Renaissance art. This year they failed to do that. That's the school's side of the story.

I don't know who's telling the truth, of course. But if they've taught David before with no problem, it seems likely that notification really was the issue.

So here's what we've got: A few parents at a conservative school didn't want their sixth-grade children to see artwork of nudes. They wanted to be notified beforehand so they could pull their kids from that particular lesson. At about the same time, for this lapse and for other reasons, the board fired the school's principal.

In what way is this even much of a local news story, let alone a national one?
