If you observe closely enough, you can detect the underlying truth in the responses of even the most practised politicians. This week delivered an instructive example.

Scott Morrison, Gladys Berejiklian and Daniel Andrews were each asked, naturally enough, what they thought about Sydney and Melbourne's eye-catching protests of a loose coalition of anti-lockdown, anti-vaccination, anti-Bill Gates and apparently anti-personal hygiene activists.

On the protesters, there's really not much to say.  They may be stupid, deluded or nihilistic; who knows, they may be conscientiously attempting to bring on the rapture in which the prime minister believes.
