Regardless of sides, or views. I don't think the issue is giving 20 million people a vote. More that the proposed plebiscite is looking to be a big waste of money, with a large number of politicians saying they wouldn't support the legislation if the public does say yes. Meaning it gets back to a conscience vote in parliament. So why waste $xx_ millions, just do the conscience vote in parliament - that costs nothing extra. The majority public view is pretty much known as well from polling, but there is zero point in asking everyones opinion if they aren't going to implement that view any way.
Its an interesting philosophical question isn't it? (irrespective of the topic in question)
On the one hand "Let the politicians decide ... that's what they are there for"; on the other hand "Hang on, this isn't a 'government / governance' issue, its overturning umpteen hundreds of years of convention, and the people
might actually not agree with the majority who have their backsides on the leather this year".
In general, although I
do trust the government (as opposed to politicians), if it comes down to a vote of the people vs a vote in parliament (which is exactly what is being debated at the moment), I go for a vote of the people.
I recall the republic referendum (yes, I know its a plebiscite this time, not a referendum) - how loud was noise and 'public support' for a republic .. "..everyone I know is going to vote yes ..." etc. And the republic went down in a screaming heap. Sometimes the media noise and support, and opinion polls didn't reflect the true public opinion. On controversial issues, people in opinion polls tend to give the answer they think is the "right" one, as dictated by the media noise, rather than what they truly believe.
I suspect that the resistance to a public vote is that the pro-change group suspect that the public vote will go against them. The arguments about a possible hate campaign is just scare tactics and speculation. I think we got through the vote to include Aboriginal persons in the census and to allow the commonwealth government to make laws for them without dissolving into a foam-flecked rabble.
And the waste of money issue? Some say the Royal Commission into Institutional responses to child abuse was a waste of money. Police have the powers to investigate all that stuff, so why waste time and money on a RC? (NB I don't agree with that proposition - there were wider issues at stake). Its always a balance between general good and practicality.
I think supporters of the proposal should embrace a public vote. If they win, as they say they will, then that will settle the issue: no come-back, no more debate. Most of the current pollies appear to support it so game, set, match. If the politicians vote their personal opinions then the issue will NOT be settled in a large slice of the publics mind, and it will continue to fester.
