I worry about Gerard Henderson, really. He has a chronic case of corresponditis — the inability, at the end of a protracted exchange of letters, to allow his correspondent to have the last word. Whenever clinicians consider this affliction they go straight to the Sydney Institute’s Media Watch Dog website. It is a case study in fanaticism, always a worrying state-of-mind in public life.
It is said that the definition of a fanatic is someone who redoubles his efforts when all is lost. This captures the Henderson method. Even when he is hopelessly wrong, he keeps churning out correspondence. Write a letter raising the slightest hint of criticism and he will send you a post office-full of replies. Al Gore might have invented the internet but by sheer weight of emails, Gerard is close to busting it.
