between prescriptivists and the practicioners of the Humpty Dumpty school on this board

Let's see what my handy dandy universal translator spits out: "betwixt uptight old Missises Grundies and descriptive linguists". OK, I understand you now. BTW, what's the plural of Mrs? Putting on my prescriptivist tam o'shanter, shouldn't between (cf. unique) only be used with two single entities on either side?

Ceci n'est pas un seing.
