CCP policy and behaviour towards Xinjiang shows a clear intent to eradicate Uighur culture, possibly the Uighur people, on the part of the CCP state. Simlilarly for Hong Kong, Tibet. A warcrime by an Australian soldier is being dealt with as a matter of military discipline.
There is no equivalency between the two. Pretending that a crime is equivalent to state genocide is classic "wolf warrior" trolling.
A better equivalency would be between what's happening with the Uighurs and what happened to Australia's first nation people in the nineteenth century. Modern China does have more than a little in common with those old European colonial empires.
