True. I was thinking of the school milieu where I have some experience: what you might call the elite private-school world. I don't have any direct experience of parochial schools, though many working-class parents strongly prefer them over public schools, and not necessarily because they're Catholic. What little I do know suggests that parochial schools may actually be an improvement on the public ones -- less bureaucratic, less rigid, more focused on core competence, more reasonable in the article of homework, perhaps even generally more humane.
About 'evangelical' schools I know nothing at all.
Some years ago I wrote an essay -- it was called "Procrustes Prep," I think -- about the elite private-school world. Couldn't get it published anywhere, but I'll see if I can dig it up.
