Slate Article Claims: If You Send Your Kid to Private School, You Are a Bad Person

This article appeared in Slate a few days ago, claiming that you are a bad person if you send your children to a private school.

Reading this, I wondered at first if it was satire. The author's argument is that you should send your kids to the neighbourhood school, even if it is a bad school, in order to 'support public education'. Unfortunately, this article doesn't appear to be intended as satire, even if it reads very much like satire.
