Popular consensus isn't always right though....just ask the Germans. You're totally entitled to think the majority of those who oppose the anthem are would be victims or virtue signalling loonies..... but your opinion is subjective, regardless of whether it has mainstream support. I think most arguments by those who condemn those who don't want to signjh the anthem are pretty damn inarticulate myself...especially as many of them often extol the virtues of free speech and expression.
Yep it's true, anyone's opinion of anyone else and their reasons for signing or not singing are subjective.
But my argument isn't just limited to whether or not they sing. My argument is that the best way to unite a population of people who differ along so many lines is to unite behind a nation and that nation should be defined with a certain set of values (that someone might call that nation's culture).
So by not singing the national anthem, to me you are basically saying the country is oppressing you or doing something to you that you think is manifestly unfair.
I find that hard to believe in a country like Australia where you can practically do or become anyone you want to, regardless of skin colour, sexual preference, gender, religion, politcal affiliation, family wealth etc etc.
Of course statistics show that certain groups of people do better than other groups of people (e.g. indigenous outcomes versus non indigenous outcomes), but you would have to analyse that data along a huge number of lines to even begin to understand why those outcomes are happening.
Should the non indigenous people believe that australian society is somehow holding back indigenous people? I highly doubt that. But at the same time it's clear indigenous people have far worse outcomes than the rest of the population.
Reducing those outcomes to some misguided belief that somehow Australia is racist and oppressive is just silly. It doesn't even begin to consider that the outcomes could be for a myriad of other reasons.
