I'd wager most of that 70% is white. Changing the date wouldn't stop you from having the ability to celebrate the 26th if you would still like. What it would do is show that a majority of white people can empathise with a minority of indigenous people and show a bit of flexibility. Pick a date we can all celebrate together.So 70% or more of Australians want the date kept at 26th january, changing the date would create a lot of animosity against the Aboriginal people, creating a "voice to Parliament" based on race is racist and would again separate us based on race , more should be done now its 2023 to improving lives and outcomes for aboriginal kids rather than dividing the country.
