I suppose that Sir SR got his K for services to literature or something. Objecting to it on other grounds is foolish. I mean, imagine (just imagine for a moment) that Gary Glitter wrote a series of wonderful musical pieces, and then got a K for services to music. Would we object on the grounds that not only he was a convicted paedophile but also that some of his earlier "musical" works were thinly disguised paeans to paedophilia?
