The reason the flag hasn’t changed is the gut feeling of the majority is the issue has been hijacked by questionable progressives. You can see here, the wordsmiths using Wikipedia quickly moved on from the difficulties and trauma of indigenous Australians. It was little more than virtue signalling; the rest of us aren’t going to buy “internalised colonialism” having seen the issues first hand and the gut feeling it’s just another progressive agenda that will go nowhere.
If you’ve read this thread please educate yourself on some of the issues thrown right back at those of us who just question why? Understand history, what was going on in the world at the time and try and find accuracy in the subjects such as the Frontier Wars or what young Australians may have fought for. I’m quite shocked having returned to Australia at the complexities of agendas. We have Manchurian Candidates in politics, a flag or indigenous issues they really couldn’t care about, however, if it can break alliances or cohesion they’ll be on to it. Business interests ably exemplified by former politicians advocating not so subtlety for the CCP.
Make a hobby of being a bit more of a historical sleuth and be ready to stand up when the wool is pulled over your eyes. It’s quite frightening having seen the COVID world and the power of social media and still the conventional press.
