Bill Leak is, presumably, enjoying his status as a one-man outrage generator. Why he’d want to be that person is unknowable. There is a case for not acceding to his desire by giving his work free publicity and leaving it known only to the demographically specific readership of The Australian. Faint hope though.
The giving and accepting of public outrage run in a recursive loop now; both parties to the bargain get the emotional feed they seek and the media gladly accept the bonanza of cheap and easy content generation.
