"Something sensible would have to be agreed on carbon pricing..."

The only 'sensible' position on carbon pricing / carbon taxes is to remove them altogether, and agree to enjoy the bounty delivered to us by increasing CO2 and the currently high global temperatures, while they last. Since no major party has the courage to support that yet, any current coalition or deal is likely to continue doing something stupid.

We can only hope that it becomes progressively less stupid over time.

“Centrism means standing for being sensible, for behaving professionally, for acting like adults...”
Says who?
I would suggest it could be far more credibly argued that Centrism stands for:
Having a bob each way,
Having no principled stand on anything,
Having no core beliefs,
Being prepared to make endless compromises for the sake of staying in power...
…
Okay, both major parties are Centrist.

perverting marriage is regressive not progressive. Turnbull was unelectable as leader of the Liberal party as he swallowed the gw lie. Abbott might get up the leftist nose but polls since he took over say it all. Suck it up guys.

runner,

Turnbull is eminently electable....

But since Abbott has garnered a modicum of support in the great "centrist" tradition of: "I don't really stand for anything, except that I'm against whatever the other side is for.", he's got his nose in front in the polls.

If Turnbull was to take over, he'd be "streaks" in front.

"suck it up guys"

Now runner, that does not sound very um, er ... Christian.

Sounds more like the devil in sheep's clothing.

Yes, Runner's positions on everything are endlessly fascinating.
His God advises us to “Judge Not...”
Unless your monicker be Runner?
God also apparently allows the continuing existence of the Devil, evil incarnate; apparently because it's important to Him that individuals be allowed the freedom to make their own choices voluntarily.
What a shame God didn't have Runner around 5,000 years ago, to advise against some of His sillier ideas.
