The deletion of one (or even a couple of dozen) school articles doesn't hurt Wikipedia. This action may affect the reputation of the administrator involved for a short term, but that also will recover.
The following AfD closes by Neutrality also seem a little odd. I see no evidence of consensus.

The following close by Neutrality was technically in order, except that someone seems to have tampered with the nomination two days ago, so that the article linked to was not the article originally nominated:

Neutrality was clearly aware of the switch, because he deleted *both* articles, although none of those voting on deletion had had any opportunity to view the Albany article, as at the time all votes were made the article listed for deletion was the Oceanview school in Clovis.
