Was Christopher Isherwood a noble man because he was homosexual, or was he a homosexual whose life was, well, sordid? (Letters, July 23). If political correctness prevents us from calling a footloose existence with 400 lovers "sordid", how can we argue convincingly for the valuing of monogamous same-sex relationships? Biography does not have to be hagiography because its subject is homosexual. So, no apology required.
