You clearly feel very strongly about the queen and about this subject, but I think you may be doing exactly what you are accusing other people of doing.Grace isn’t a race or blood. Nobility, respect and gratitude are character traits admired but hard to find across peoples. Continually defining people by their skin colour or sex is shallow and divisive. We can acknowledge all our history without dividing ourselves.
I don’t think I do have aboriginal heritage but you never know? My ancestors were bought here in chains 7 generations ago, I am a native of this land, it’s the only land I know and I respect it. If we are going to sing the National anthem and acknowledge the indigenous the least we can do is honour our Queen of 70 years with ONE minutes silence?
I'm sure that the AFLW's actions are driven by the thoughts and beliefs of the indigenous women competing in the competition rather than the prejudices of middle class white people as you suggest.
