  This fun polemical piece was written several months ago on a tip that the
\emph{Chronicle of Higher Education} might be interested in publishing
something like it. Sadly (both for me and, I think, for the \emph{Chronicle}'s
readership) the editors didn't think it was of sufficient interest to the wider
academic community. I am posting it here at the arxiv so that it can,
nevertheless, be publicly available. If anyone out there wants to (suggest a
place to) publish the piece, I'm all ears.
