Clyde Haberman in the New York Times:
Ms. O’Conner said there is a flip side to the rejection of all grammatical structure. It is slavish adherence to old rules and intolerance for any perceived transgression.
She gets an earful, she said, when she writes that there is nothing horrific about, say, splitting an infinitive or ending a sentence with a preposition. For some people, those are heresies to always object to.
