"What is a dry run?"

Are you incompetent at using Google or dictionaries?

dry run

"a rehearsal of a performance or procedure before the real one."

Clearly, you are nearly illiterate.

It is false to suggest that people are being
cajoled into thinking that they have some sort of
"duty" to vote "Yes" rather than actually create an
appealing formula for constitutional change.

This is deeply disingenuous because these people
are ones who would disapprove and oppose - no matter
what model was presented. They are blabbering on
about "detail," when there is the model
for the Voice presented by Professors Marcia
Langton and Tom Calma:

More detail will be revealed as the process develops.
It will be interesting to see how much support these people
doing the criticism now
give as more detail is provided. I suspect they will continue
to oppose - because their opposition is nothing more
than virtue-signalling.

"The model of the Voice is not what the referendum is
about. It's about ensuring that there will always be a
First Nations Voice in the centre of decision-making, and
that First Nations people are recognised and respected for
their sovereignty that was never ceded or extinguished.

Here is what Prof. Marcia Langton has to say:

"cajoled into thinking that they have some sort of
"duty" to vote "Yes""

Why did you put duty in quotes? No one said 'duty'. Who are you quoting? You have a real problem with this notion of quoting don't you. Its not that hard. If you use other peoples words you put it in quotes (unless you want to try to elevate yourself by pretending they're your words), otherwise quotes ("") aren't needed (unless you want to pretend that others said things they didn't say).

I'm not saying you are blindly falling into line over the Voice out of duty. I'm saying you're doing it out of habit - just doing what those you accept as your betters tell you to do.

I don't care what Marcia Langton or anyone else says the Voice will look like. I only care what the final decision is/will be. Until then its all ideal speculation and I'm not going to sign up to a notion that is as yet undefined.

Until vital issues like 'Will it be elected?' are resolved, everything is up for grabs. You don't know if it'll be elected yet are happy to go long with it anyway. I'm not.
