Megan McArdle would like to know which you find more offensive:

That your child "...might hear, once a week, some sort of religious message which, to judge by the people I know who went to parochial school, has a fairly dim chance of sticking; or that junior won't be able to read and write and will spend the rest of his life moving heavy things from one place to another?"

I'm tempted to read her commentary at one of my town's Board of Ed meetings, verbatim.
