Similarly, say, for Hardy Amies. I don't care that his predictions about the future of men's style were awful. He remains a top notch non-professional historian, with an insider's insights into the history of British classic style. Like anything, read it for what's valuable and discard the irrelevancies (for example, I pass over without further comment his occasional lapses into distasteful chauvinism).
Ditto for all authors, surely?
