The (presumably) forthcoming double dissolution will raise many issues. But most of them can be summed up as the defence of Australian institutions that have been under attack by radical extremists. I’m referring to such institutions as the ABC, CSIRO, the weekend, public education, the union movement, the fair go and our natural environment. Mention of any of these is enough to raise a derisive sneer from the radical rightwing apparatus that dominates much of Australian politics, most obviously the supporters of Tony Abbott who (ludicrously) call themselves “conservatives”. Turnbull promised something better but he is campaigning against all the institutions I’ve mentioned. It’s time to tell those who want to undermine our way of life in the name of free market ideology and rightwing tribalism where they should get off.
