C. S. Lewis wrote the preface of the book How Heathen is Britain ? by B. G. Sandhurst, London: Collins, 1946.  In a note to his comments, he said, "... Throughout this preface boys means boys and girls , and schoolmasters includes schoolmistresses . There is lot to be said for political or economic equality of the sexes: but the claim for grammatical equality of genders is an unmitigated nuisance which should be resisted wherever it is met." Lewis was not a mysogynist.  He loved the English language and the logical flow of discourse.  And I  agree with him: interruptions in language for the sake of political statement is both distracting and linguistically ugly.
