Why do Aussies write books like this?

[Ozmaniac]

Fair go mate! One Australian writes one book and you ask why Aussies (plural) write such books?

The anti immunisation crackpots make a lot of noise and are very vocal on the internet, but they're only a tiny minority. Few Australians fall for their rubbish and our government, health authorities and even the current affairs programs on television (including the ones that normally jump on any old bandwagon for sensation's sake) are ardent supporters of immunisation. Immunisation rates have been dropping for many years but that's mostly due to ignorance and apathy rather than any philosophical objection on the part of most parents.
