But once introduced, a prescriptive rule is very hard to eradicate, no matter how ridiculous. Inside the educational and writing establishments, the rules survive by the same dynamic that perpetuates ritual genital mutilations and college fraternity hazing: I had to go through it and am none the worse, so why should you have it any easier? Anyone daring to overturn a rule by example must always worry that readers will think he or she is ignorant of the rule, rather than challenging it. (I confess that this has deterred me from splitting some splitworthy infinitives.)
