You want people to engage with you, you need to have an open discussion. That involves elaborating on and justifying your position, rather than just posting narrow socratics and expecting people to kowtow to them.
It is all about the numbers, and IMO she doesn't have them. Bob Brown's patronage is the only reason she's sitting in that chair.
Maybe as a mod you should set an example then. Milne has 'the numbers' (as you call them), and was elected as leader. Brown's patronage has nothing to do with it. She is the most experienced senator and the only Green in the party room with leadership experience.
