I'm both an Australian and NZ citizen. One of my parents is Australian and the other NZ.
Not that my ancestral line matters at all the legitimacy of my views. I spent 30 years living in Australia and I'll point out all the flaws I want.
Otherwise, nobody in Australia should ever criticize China (or insert any other country). But that's not the way the world works, nor the way I want the world to work. Everyone should be held to account. We don't exist in a vacuum.
