George Orwell said this quote

When you meet anyone in the flesh you realize immediately that he is a human being and not a sort of caricature embodying certain ideas. It is partly for this reason that I don't mix much in literary circles because I know from experience that once I have met and spoken to anyone I shall never again be able to feel any intellectual brutality towards him even when I feel I ought to - like the Labour M.P.s who get patted on the back by dukes and are lost forever more.
