It has nothing to do with anyone becoming “conservative”. Another advisory board would change nothing when the ones we already have are ignored and aren’t working.
60% of the country voted for gay marriage, a far more “liberal”/“progressive” thing than the voice, so saying we’re getting more “conservative” makes no sense. The fact is that the actual progressive people recognize that this was all grandstand virtue signalling, and we want more than that. “It’s better than nothing” is not a valid reason to change our constitution. How about actually doing something meaningful as a starting point instead?
This wasn’t “progress or not” though, that’s ridiculous and sore loser talk. Another toothless advisory panel that will be ignored isn’t “progress”.
Real progress would be something like guaranteeing some new seats at the senate to go with the “voice”. Give them an actual voice that gets to decide on things that affect their community. Giving them a “voice” that can and will be ignored will change nothing for the better.
