They were colonized a very long time ago. Point stands they can leave anytime they want. Just like other countries have done.
NO. Not a long time ago. Go educate thyself. My grandmother had land taken by force, not ages ago. Ok.
We, the colonised, cannot leave. We are depleted in numbers, half of us dying because of the diseases British brought to our lands and then by being colonised and intentionally ‘assimilated’. This was a crown policy in NZ, ‘ to assimilate the natives’ by encouraging and rewarding mixed marriages to ‘breed out the natives’, and like Hawaii and others, decreed anyone less than 50% to be ‘not native’.
Go educate your ignorant self.
